USPS Address Validation & Delivery Issues – Multi Carrier Shipping Label App for Shopify FAQs

    FAQs on USPS address validation, delivery errors, delays, and failed deliveries in Shopify

Questions in this section:

Will connecting my EasyPost account to Shopify enable international shipping through Passport using USPS via EasyPost as a shipping option?

Connecting your EasyPost account to Shopify can enable international shipping through Passport using USPS via EasyPost. However, it is crucial to ensure that your EasyPost account details, such as the company name and return address, are properly configured to match your merchant information. If you encounter errors like “Merchant not found by provided company name,” you need to contact EasyPost support to update your account details correctly. Proper account setup with EasyPost and Passport is essential for the shipping rates and label generation to work seamlessly.

Why is the USPS shipping option not showing during checkout and why are some orders defaulting to Shopify’s rates instead of USPS rates?

The USPS shipping option may not show if the app is unable to pull rates due to authentication issues. Specifically, an error like “Authentication failed. Bridge exception code 0x002b0601; module 43, category 6, item 1” indicates that the USPS/Stamps.com login credentials used by the PluginHive app are invalid or outdated. To resolve this issue: 1. Verify if you have recently updated your Stamps.com login credentials. 2. Attempt to log in directly to the Stamps.com website using the same credentials connected to the app to confirm they are correct. 3. If credentials have been changed or expired, update them within the PluginHive app: – Go to the app dashboard – Navigate to Settings -> Carriers – Update the Stamps.com credentials with the current login details 4. After updating, test the checkout process again to ensure USPS rates now appear. This will restore USPS rate fetching and prevent Shopify’s default shipping rates from being applied erroneously.

Why is the estimated delivery time showing at checkout for UPS and FedEx but not for USPS in PluginHive?

UPS and FedEx provide estimated delivery days through their APIs, so PluginHive can display these estimated delivery times at checkout. However, USPS does not currently supply estimated delivery days via their API, which is why the estimated delivery time for USPS is not shown at checkout. This is a limitation from USPS’s data availability, not a PluginHive settings issue. PluginHive is working on a solution to enable estimated delivery dates for USPS in the future, but at present, this feature is not supported for USPS shipments.

Why is my order showing “no matching automation rule” even though it falls into the correct shipping zone with the expected USPS shipping options?

This issue often occurs because the shipping zone is configured with multiple conditions (such as postal codes and country states) combined with the “Match All Conditions” option enabled. When “Match All Conditions” is enabled, all conditions must be true simultaneously for the rule to apply. If your zones use postal codes and states as separate conditions, this may prevent the rule from matching correctly. To resolve this: 1. Disable the “Match All Conditions” option under App > Settings > Shipping > Shipping Zones. 2. Reprocess the affected order after this change. This should allow the order to match the correct automation rule and move to processing status successfully.

Why does the USPS label creation fail for the customer’s address on order #111459 with an “invalid address” error, even though the same address works on Pirate Ship, and how can this be fixed?

The label creation failure for order #111459 stems from an error related to the shipping address details sent to USPS via the PluginHive integration. Specifically, the error messages include: – “Ship from or ship to address invalid, provide valid address” – “Invalid SOAP message due to XML Schema validation failure” – A note that the ‘CountryOfOrigin’ element is invalid because its value is empty or shorter than expected, despite the country being set as “US”. This indicates that in the XML communication with USPS/Stamps.com, the ‘CountryOfOrigin’ element is either missing, empty, or not conforming to the required format, causing USPS to reject the label request. To resolve this issue: 1. Verify that the shipping address provided in Shopify for the customer includes all required fields correctly filled, especially the country code. This includes: – Recipient’s full name – Complete street address without unsupported characters or formats – City, state, and ZIP/postal code – Country code set explicitly as “US” or the relevant two-letter ISO code 2. Check PluginHive app settings and mapping to ensure that the ‘CountryOfOrigin’ or equivalent country field is correctly passed from Shopify to the USPS API. Sometimes, a missing or misconfigured field in the integration can cause the XML to omit this value. 3. If the address details appear correct in Shopify, contact PluginHive support with the order number and XML error logs so their technical team can analyze if the application is improperly formatting or transmitting the address data. 4. Meanwhile, as a temporary workaround, continue generating the label through Pirate Ship or any external software that accepts the address correctly. 5. Avoid making further changes or attempts to generate the label for this order within the PluginHive app until the problem is resolved, as repeated failed attempts may complicate troubleshooting. In summary, the root cause is a technical validation failure of the address data sent to USPS via PluginHive’s integration, likely due to an empty or malformed ‘CountryOfOrigin’ field in the XML payload. Confirming the address correctness in Shopify and engaging PluginHive support with diagnostics is the recommended path to fix this.

Why does the USPS label creation fail for my order when the shipping address appears valid and works on Pirate Ship, and how can I fix this issue in PluginHive?

The label creation failure typically occurs because the shipping address data sent via PluginHive to USPS is incomplete or improperly formatted, causing validation errors. Common causes include the absence or incorrect value in critical XML fields like the ‘CountryOfOrigin’ element, which USPS requires for customs and address validation. To fix this: 1. Verify that the customer’s shipping address in Shopify contains all required details: – Complete recipient name – Full street address without unsupported characters – Correct city, state, and ZIP code – Explicit two-letter country code (e.g., “US”) 2. Check the product-level information, especially for international shipments: – Ensure the ‘Country of Manufacture’ (Country of Origin) is set for each product in your Shopify store. – Make sure the Harmonized System (HS) Code is also filled if required by the carrier. 3. Confirm that these product and address fields are properly mapped in PluginHive’s integration settings so they are included in the shipping label request XML. 4. After updating product details like ‘Country of Manufacture’ and address data, try generating the shipping label again from PluginHive. 5. If the problem persists, provide PluginHive support with the order number and XML error logs to investigate if the integration is correctly transmitting the data. In summary, the failure is due to missing customs information—especially the empty ‘CountryOfOrigin’ field in the label request XML—and can be resolved by completing these product details and verifying address accuracy before label generation.

Why does the system reject a shipping address as incorrect even when it appears correct, and how can I resolve postal code or city name mismatches for USPS shipments?

The system validates shipping addresses using USPS Address Lookup, which may suggest alternate postal codes or city names different from what appears on your order. To resolve such mismatches: 1. Cross-check the address against USPS Address Lookup recommendations. 2. Update the shipping address fields to match USPS standards exactly, including using the city name and ZIP code suggested by USPS (for example, setting City as “White Bear Township” when USPS recommends it, instead of another variant). 3. Test the label generation again after making these corrections. 4. If the issue persists, consider checking alternate ZIP codes or contacting support with the exact address details for further analysis. Following USPS-approved address formatting ensures compatibility with carrier APIs and prevents address validation errors during shipping label creation.

Why do I get an “Authentication Failure” error when adding my USPS (eVS) account using USPS legacy web tools APIs, and how can I resolve it?

The “Authentication Failure” error typically occurs when the USPS credentials (web tool userid and password) are either invalid or not yet approved for API usage. USPS requires you to complete specific steps to get your API credentials approved, which are usually detailed in the email they send you after registration. If you have followed those steps but still face issues, a recommended workaround is to integrate your USPS account through EasyPost, which simplifies authentication and management. You can follow this guide for integration details: https://www.pluginhive.com/knowledge-base/integrate-usps-easypost-on-shopify/. Alternatively, you may schedule a call with support for hands-on assistance in completing the integration.

Why are USPS shipping rates no longer showing up for customers in Puerto Rico and Hawaii after initially working for a few weeks?

When USPS shipping rates stop appearing despite previously working, it usually indicates a failure in rate retrieval from the USPS service. To troubleshoot this issue: 1. Check the app’s request logs for specific errors associated with USPS rate requests. Look for failure messages indicating problems with the USPS API or authentication. 2. Verify if there were any recent changes to your USPS account credentials, API keys, or the store’s shipping settings that might have affected communication. 3. Confirm that the app is still actively connected and authorized to fetch rates from USPS. 4. Review whether USPS service disruptions or temporary API issues might have caused the failure. 5. If you observe a specific request failure error code or reference ID in logs, share this with PluginHive support for detailed analysis. 6. Ensure your store’s shipping zones and packages are configured correctly for Puerto Rico and Hawaii addressing as per USPS standards. 7. If the problem persists after these checks, contact PluginHive support with detailed failures and request logs for further investigation. This structured approach helps pinpoint the root cause of USPS rate unavailability and guides corrective actions.

Why are USPS shipping rates no longer showing up for customers in Puerto Rico and Hawaii after initially working for a few weeks?

When USPS shipping rates stop appearing despite previously working, it usually means the app is failing to retrieve rates from the USPS API. To troubleshoot: 1. Check the app’s request logs for any error messages related to USPS rate requests, including authentication or API failures. 2. Verify if there have been recent changes to your USPS account credentials, API keys, or store shipping settings that might disrupt communication. 3. Confirm that the app remains connected and authorized to fetch USPS rates. 4. Check whether USPS is experiencing any service disruptions or temporary API outages. 5. Review your store’s shipping zones and package configurations for Puerto Rico and Hawaii to ensure they meet USPS addressing standards. 6. If request error codes or reference IDs appear in your logs, provide these to PluginHive support for further diagnosis. 7.

This methodical approach helps identify why USPS rates are unavailable and guides corrective measures.

Why are my USPS pickup requests failing with the error “Last name is missing. It is a required field,” and how can I fix it?

Pickup requests fail because the From Address in your PluginHive app lacks a required last name field. To fix this: 1. Go to the app’s From Address settings. 2. Ensure that the Person Name includes both a first and last name (the last name is mandatory). 3. Save the changes. Future pickup requests should succeed once the last name is properly added. For orders where pickup has already failed, you may need to schedule pickups directly on the USPS website as a workaround.

Why am I receiving the “Insufficient OAuth scope” error when generating USPS labels through the API, and how can I resolve it?

The “Insufficient OAuth scope” error indicates that the OAuth token used in your API request lacks the correct permissions to access the USPS label generation resource. To resolve this issue: 1. Verify your current OAuth scope and API product access. The default product access includes OAuth, Addresses, Service Standards, International Pricing, Domestic Pricing, Shipping Options, Locations, and UserInfo. Label generation requires upgrading to a product that explicitly supports this feature. 2. Submit an application to USPS to upgrade your API product and quota to include label generation capabilities. Provide USPS with the following details: – Consumer Key – CRID (Customer Registration ID) – Estimated maximum daily shipping volume at peak 3. Await USPS manual review and approval of your application. Once approved, your OAuth access will be enhanced to support label generation. 4. Note that OAuth access tokens and payment tokens issued are valid for 8 hours; avoid regenerating tokens for each API call to maintain efficiency. 5. After product upgrade, ensure your API requests use the updated OAuth tokens associated with the new access scope.

Why am I only seeing USPS shipping rates at checkout and not UPS rates after recent changes in PluginHive?

The reason only USPS rates are visible at checkout is that the UPS rate automation rule in the PluginHive app was temporarily disabled. This was done to isolate and address an issue specifically related to UPS rates not displaying properly. As a result, only USPS (via Stamps.com) rates are currently shown to customers as a temporary workaround. To restore UPS rates alongside USPS rates, the PluginHive team is actively investigating and working on a fix. Meanwhile, customers can place orders using the USPS rates shown, but the UPS rates will return once the issue is resolved.

Why am I not getting a Hawaii FedEx shipping rate for orders shipping to Hawaii, and only USPS rates show instead?

The likely reason for not seeing the Hawaii FedEx rates is due to the configuration of FedEx accounts and automation rules in the app. Here’s how this scenario typically works and how to troubleshoot it: 1. Multiple FedEx Accounts Setup: You may have two FedEx accounts in the app — one configured for all US states except Hawaii (with the “One Rate” option enabled), and another dedicated to Hawaii orders (with the “One Rate” option disabled). 2. Automation Rule for Hawaii: There should be a rate automation rule that triggers the use of the Hawaii-specific FedEx account when the destination address is in Hawaii. 3. Issue with One Rate Parameter: Despite the Hawaii automation rule triggering correctly, the system may be incorrectly passing the “One Rate” parameter as enabled for the Hawaii account, even though it is disabled at the account level. This mismatch causes FedEx not to return any service or rates, resulting in no Hawaii FedEx rates being displayed. 4. To resolve this, verify the following: – Confirm that the Hawaii FedEx account has “One Rate” disabled. – Ensure that the rate automation rule correctly distinguishes between the Hawaii and non-Hawaii accounts and does not pass conflicting parameters such as “One Rate” enabled for the Hawaii account. – Check the integration logs for error details or misconfigured parameters related to One Rate when the Hawaii rule is triggered. 5. If the issue persists, provide the request log ID and store details to the PluginHive support team for deeper investigation. In summary, the root cause is a mismatch of the “One Rate” setting in the Hawaii FedEx account leading to no rates being returned, even though the automation rule for Hawaii is firing as expected. Adjusting the configuration and validation of these settings will restore Hawaii FedEx rate visibility.

The error “2013deee5cf39bd61d7ccf112de4ff836d66e697dafb801e11d1d58213ea130e unavailable” typically indicates an issue with USPS API connectivity or a problem with the request sent to the USPS servers. To resolve this: 1. Verify your USPS account credentials and ensure your API access is active and properly configured in PluginHive. 2. Check for any formatting or data errors in the shipping request that might cause USPS to reject it. 3. Since this error relates to USPS server connectivity, contact USPS support directly with details of the error and share any related XML request files for troubleshooting. 4. Meanwhile, confirm that your PluginHive shipping settings for USPS are correct and up to date. Following these steps will help identify and resolve the issue causing USPS label generation failures.

Why am I getting a label generation error with a message like “unavailable” when creating a USPS shipping label in PluginHive?

This error typically occurs when the billing details are not fully set up or verified in your USPS account. To resolve this: 1. Verify that your USPS account billing information is complete and accurate by logging into your USPS business account. 2. If uncertain, contact USPS customer support directly and provide them with the RequestResponse XML file related to the label failure for your specific order (e.g., Order #RAMPZ 1386. to help them diagnose the issue. 3. Once USPS confirms your account billing details are fixed, try generating the label again in PluginHive. 4. If the problem persists or you need assistance obtaining the XML file, contact PluginHive support with relevant order details for further help.

Share the raw JSON payload and API endpoint details used during the label generation attempt, as these are required for advanced investigation with USPS. 4. If needed, escalate the issue to PluginHive support and USPS technical teams, providing the captured logs, raw JSON, and error messages to diagnose any underlying issues. This process helps PluginHive support and USPS pinpoint the exact source of failure and recommend further action.

What steps should a customer follow to authorize their USPS app to access protected information resources required for APIs?

The customer should: 1. Visit the USPS API onboarding portal at https://cop.usps.com/navigator?wf=apisonboarding. 2. Enter their Consumer Key on this page to grant the app access to protected resources, including payment accounts, permits, Customer Registration IDs (CRIDs), Meter IDs (MIDs), and subscriptions. 3. Complete any additional verification or consent steps required by USPS. 4. Confirm authorization is successful before attempting API calls requiring these permissions. This authorization is crucial to enable the app to interface properly with USPS payment and shipment APIs without permission errors.

What specific USPS account information do I need to provide to get help with adding my USPS Ship account in PluginHive?

To assist with adding your USPS Ship account, you should have the following details in hand: – Customer Registration ID (CRID) – Consumer Key – Consumer Secret – Account Number – Mailer Identifier (MID) – Manifest MID Ensure that you have completed the USPS enrollment steps as detailed previously. Provide these details to the support team so they can attempt to add the account from their end and troubleshoot the connection issue efficiently.

What should I verify if PluginHive reports unauthorized errors during USPS label generation?

Unauthorized errors during USPS label generation usually indicate incomplete or incorrect USPS account setup or API credential scopes. To troubleshoot: 1. Confirm with your USPS account manager that your account has complete setup, including verified billing and bank account information. 2. Verify that the API credentials used in PHM have the full scope necessary for label generation, including payments and label APIs. Partial scopes limited to addresses or shipping rates will cause authorization failures. 3. Check that the Mail Owner IDs (MIDs) linked to your credentials match those assigned to your USPS account in PHM. 4. If multiple mail owners are associated with your credentials, ensure the correct one with label permissions is applied. 5. Request USPS API Support to confirm if any credential or permission issues persist. Correcting these factors should resolve unauthorized errors when generating USPS labels.

What should I provide to the PluginHive support team to help with USPS integration troubleshooting?

To assist support effectively, provide: 1. Your USPS Web Tools USERID and password (API credentials). 2. The company name associated with your USPS account. 3. Clear description of the error message or issue encountered, such as ‘Authentication Failed’. 4. Any screenshots of the integration setup or error messages (if communication is via email). With this information, support can verify your account status from their end and guide you on the next steps, such as enabling required APIs or switching to EasyPost integration if needed.

What should I know about OAuth tokens when using USPS APIs after approval for higher product access?

After your API product and quota upgrade, note the following about OAuth tokens: 1. OAuth access tokens and payment tokens issued by USPS are valid for 8 hours from the time of generation. 2. Tokens should not be regenerated with every API call. Instead, cache and reuse your tokens until they expire to optimize performance and avoid unnecessary authentication requests. 3. Ensure your API requests include a valid OAuth token with the appropriate permissions aligned with your upgraded product access.

What should I do to get help with USPS integration issues after submitting my USPS account details to PluginHive?

When submitting USPS account details to PluginHive for integration support, ensure you provide the following information accurately: – Customer Registration ID (CRID) – Account Type (e.g., EPS) – Account Number – Mailer Identifier (MID) – Manifest MID – Return MID – Consumer Key – Consumer Secret Once provided, PluginHive support will verify the details and test the integration from their side. If errors occur, PluginHive will investigate for API compatibility issues or other causes and communicate further instructions or updates to you.

Contact PluginHive Support to create a support ticket including this information for escalation. 3. PluginHive will coordinate with USPS or UPS support teams to investigate the issue behind the code. 4. Meanwhile, confirm that your store setup, shipping services added (such as UPS or USPS) and subscription plan (e.g., $29 popular plan) are valid and active within PluginHive. 5. Follow up with PluginHive for updates on the ticket resolution. This error typically requires backend investigation by PluginHive and the carrier’s support teams.

What should I do if the USPS Ground Advantage service is essential for my shipping options but is not showing at checkout in PluginHive currently?

As the Ground Advantage service is currently unavailable at checkout due to the known display issue: 1. Temporarily use alternative shipping carriers or services, such as UPS, for fulfilling your orders to avoid disruption. 2. Inform customers about possible changes or limitations in shipping options during this interim period through your store communications. 3. Monitor PluginHive updates closely for the deployment of the Ground Advantage display fix. 4. Once the update is released, test the checkout to confirm that USPS Ground Advantage appears correctly before switching back. 5. Coordinate with PluginHive support for status updates and assistance regarding the rollout.

What should I do if my USPS Ship account still shows as “INPROGRESS” or is not recognized despite completing the enrollment steps?

If your USPS Ship account status remains “INPROGRESS” or is not associated properly after completing the enrollment steps: 1. Log in again to the USPS Customer Onboarding Portal (COP) at https://cop.usps.com and carefully verify that you have completed every step, including ACH debit setup. 2. Confirm your ACH debit account is active and verified by checking your bank deposits from USPS. 3. If you have recently verified deposits, allow some processing time for the system to update your enrollment status. 4. If problems persist, you may need to contact USPS API support to report the issue.

What does the USPS API error “Insufficient OAuth scope” mean and how can it be resolved?

The “Insufficient OAuth scope” error indicates that the OAuth token used for authentication lacks the necessary permissions (scopes) to access the requested USPS API resources. To resolve this: 1. Verify the OAuth scopes associated with your USPS API consumer key to ensure they include permissions for the APIs you intend to use. 2. If your app is only set up with the default product scopes (e.g., OAuth, Addresses, Service Standards, etc.), but you require access to additional APIs such as label generation, you need to request an upgrade or additional scopes from USPS. 3. Provide USPS with detailed information about your application, including: – Consumer Key associated with your app – CRID (Customer Registration ID), if applicable – Estimated maximum daily shipping volume at peak periods – Details of any 3rd party software or plugins you are using, if not your own solution 4. USPS will review your request and upgrade your app’s product and quota accordingly to grant the required OAuth scopes. 5. Use the updated OAuth access token and payment token, which remain valid for 8 hours and should not be regenerated for each API call.

What are the requirements to open a new Stamps USPS or EasyPost USPS account for use with PluginHive?

To open a new Stamps USPS or EasyPost USPS account for integration with PluginHive, the basic requirements are: 1. A valid billing address. 2. Contact information including phone number and email address. No complex documentation or approvals are typically required beyond these details. For detailed guidance on integrating USPS via EasyPost with Shopify and PluginHive, refer to the PluginHive knowledge base article: https://www.pluginhive.com/knowledge-base/integrate-usps-easypost-on-shopify/ PluginHive support can also assist with the account integration process if you prefer scheduling a support appointment.

What are the proper OAuth token generation steps for USPS API usage?

To generate a valid OAuth token for USPS API: 1. Send a POST request to the OAuth endpoint https://apis.usps.com/oauth2/v3/token. 2. Include the following parameters in the request body as JSON: – client_id: Your issued Consumer Key – client_secret: Your Client Secret – grant_type: “client_credentials” 3. A successful response will provide an access_token, token_type, issued_at, expires_in, and a list of scopes and permissions. 4. Use this access_token as a Bearer token in subsequent USPS API requests (for example, in the Authorization header). This OAuth token authenticates your app and authorizes access to USPS API resources per your account’s permissions.

Is it necessary to schedule a call to resolve USPS rate type and label generation issues in PluginHive?

Scheduling a call is helpful but not mandatory. Key considerations: 1. If you have all required information (account details, error logs, and specific questions), many issues can be resolved through detailed email or ticket exchanges. 2. For complex or unclear problems, a scheduled call allows real-time discussion with USPS and PluginHive experts, which can accelerate resolution. 3. Coordinate with PluginHive support and USPS representatives to confirm availability and share all relevant technical details beforehand to maximize call effectiveness. 4. Use calls primarily when asynchronous communication is insufficient to clarify configurations or troubleshoot live issues. Effective communication and prepared information often reduce the need for calls but ensure they are available when necessary.

If updating the USPS account number in the payment authorization request does not fix the 403 authorization error, what should be done next?

If simply changing the account number does not resolve the 403 authorization error when accessing /payment-authorization: 1. Request the customer to re-complete Step 5 on the USPS “Getting Started” page, which involves explicitly authorizing the app to access protected USPS information resources, such as payment accounts, permits, CRIDs, MIDs, and subscriptions, by entering the Consumer Key on USPS’s portal. 2. Confirm the authorization process is completed successfully and that the app is recognized as authorized for those resources. 3. Retry the API request with the updated authorization. 4. If issues persist, provide USPS support with updated full request and response details for further investigation. Completing this authorization step is critical to ensure permissions are granted for payment-related API calls.

How should I handle orders where the app incorrectly changes the carrier after assigning a USPS box?

When this issue occurs: 1. Identify the affected order that has USPS as the carrier but changes to FedEx after you manually assign a USPS box. 2. Manually change the carrier back to USPS after you adjust the box. 3. Continue monitoring if this behavior recurs only on the first change; subsequent box edits should retain the USPS carrier. 4. Record the issue with a screen recording when it happens to help support replicate and investigate the problem further. 5. Contact support with the order details and recording for assistance and to facilitate troubleshooting.

How long does it typically take for USPS to review and approve API app upgrade requests?

USPS manually reviews each application upgrade request; however: 1. There can be significant delays due to a backlog of requests. 2. USPS does not provide exact timelines or expedited review options. 3. Requesters are advised to be patient and wait for USPS to complete their manual review process. 4.

How does PluginHive handle address validation workflows, and what should I consider if implementing USPS Address Validation API?

PluginHive does not currently have an address validation workflow integrated in the app. If you plan to use USPS Address Validation API externally, consider these points: 1. Determine when and how addresses are validated in your current workflow (e.g., at checkout, before shipping). 2. Clarify your process when an address validation suggests changes — whether to automatically replace the customer’s entered address or to require manual review. 3. Understand this will impact fulfillment accuracy and potentially reduce shipping errors and re-shipping costs. PluginHive is evaluating how best to incorporate this functionality natively in future updates.
