Frequently Asked Questions : UPS

In this article, we will be covering some of the most common Frequently Asked Questions(FAQs) that people have for the WooCommerce UPS Shipping Plugin with Print Label. Read along to know more about it.

Q1: Why am I getting an error as No tracking information available [Error Code: 151044], when clicking on ‘print label’ button? Also, I am not able to see tracking info on UPS site, while trying to test shipments.

Ans: The Tracking ID which is generated in the Test mode, is not trackable. Because of that, you are getting the error as No tracking information available. In live mode, you can get the tracking information.

Q2: Why am I getting an error as  FATAL error: Cannot redeclare class UPS_WooCommerce_Shipping?

Ans: If you have already installed the basic version in your site, you must delete the basic version and install the premium version to resolve FATAL Error.

Q3: What are the reasons for not getting correct API rates?

Ans: If you are getting incorrect rates, recheck shipper address, recipient address, service code, product dimension, product weight, insured value, and negotiated rate.

Q4: Why am I getting an error as invalid license access number with Debug mode on? And how can I fix this error?

Ans: There can be two reasons for getting the above error as given below:

1. You are getting this particular error because you may be using test credentials in the live mode. To fix this error, select Test option from API Mode field in UPS Plugin settings as shown below:

2. If you are getting above error, recheck UPS User ID, UPS Password, UPS Access Keys and UPS Account Number.

Q5: Why am I getting Error as [UPS] No rate returned for service code 12, The requested service is invalid from the selected origin. (UPS code: 111100) in Debug Mode?

Ans: The above error is shown on the cart page if UPS does not have the particular service available for the specified address(Shipper and Recipient Address). You can see the service code in UPS Plugin Settings as shown below:

Q6: Currently, I have not measured or weighed my products. Can I still print labels?

Ans: Yes, you can use the print label in manual mode. In manual mode, you can mention package dimensions & weight manually while printing label.

Q7: Can I generate only single shipping label even if customer buy more than one item?  Right now, it charges shipping individually.

Ans: Select the Parcel Packing mode as ‘pack into boxes’ & configure the package boxes also. Here is a documentation on box packing to help to understand box packing better.

Q8: While updating the plugin, will it keep the settings?

Ans: Yes, it will keep settings. Please check our documentation explaining the procedure to install and update the plugin.

Q9: Can I disable the tax calculated onto the total as I do not want to have the tax on the shipping?

Ans: You cannot disable the tax in the UPS plugin settings. UPS API returns the rates with tax.
Alternatively, you can navigate to WooCommerce > Tax > Standard Rates. Select the Shipping check-box for the required tax as shown below:

Q10: For an invalid zip code, why does UPS response with a free shipping option?

Ans: If you are getting the response with a free shipping option for an invalid zip code, make sure Fallback field is empty in plugin setting.

Q11: How can I adjust the box size to fit two products in the same box?

Ans: You select the Parcel Packing Method as Pack into boxes. Then, define the required box sizes in Custom Box Dimensions section. In this case, cart items get packed into one of those custom defined boxes. The best fit box gets auto chosen among the boxes defined.

Q12: Does UPS Plugin automatically validate Residential/Commercial addresses?

Ans: If the residential checkbox is selected in UPS settings for the rate request then the shipment will be classified as residential. There is a second validation done at the back-end and if the address is really supposed to be commercial then the classification will be changed.

Note: UPS validates only US addresses as residential or commercial addresses.

    I have downloaded your UPS plugin. I have installed it correctly. I have added weight and measurements to the products. I have linked the UPS account to our store account. I have click on debug for shipping. I have cleared the cache on our site. I have set up the backend shipping for countries. I have set up payments and linked our account to UPS.

    I go to to “my cart” I get an extremely long HTML code. Then I get an error a 1101 error stating the shipping address is not correct. So, I cleared my cache again. I have reset the Debug option. I refreshed the page. I went even to an inconginto window. I am still getting an extremely long HTML listing with an error.
