UPS SurePost on your WooCommerce Store

By using WooCommerce alone you will not be able to obtain SurePost rates and services. This can be achieved by using the Pro version of the WooCommerce UPS Shipping plugin with Print Labels.

The plugin comes fully equipped with the ability to fetch Real-time rates from the UPS API provided that the products in the store have Weights and Dimensions configured. Since UPS SurePost is a paid contractual service, it is recommended to obtain the contracted API key so that when the plugin sends the request to UPS with the weights and dimensions, UPS sends a response with the available rates for UPS SurePost and the rates are calculated Real-time within the plugin.

To obtain the contracted account credentials you will have to access and proceed to Sign Up following which you will have to reach out to their customer care team and get a clearer image of the various contractual services they provide. 

The above step can be accomplished here

Once the WooCommerce UPS Shipping plugin has been set-up you will be able to view the available services based on the UPS Access Key and the Account Number

Proceed to the store and add a product to the cart; make sure the product’s weight and dimension meet the required limit for SurePost in order to obtain rates in the front end. In the example below, the item in the cart is 1.25 lbs (weight) 7 in x 7 in x 2.5 in (LxWxH). SurePost classifies this item as large enough to be shipped using the SurePost 1 lb or greater service.

However, in the case if a customer would request to return the product or package, UPS SurePost does not support returns to the Store owner and the store owner will receive an error on the order page while trying to generate return labels so in this case an alternate shipping service will have to be used to process a return or will have to be done by the recipient of the package out of his/her own pocket.

The shipping label will specify the origin and destination, the weight of what is being shipped, and the relevant tracking numbers for both carriers. Here have a look at the sample label:

The label comes pre-loaded with both, the UPS tracking number as well as the USPS eVS (Electronic verification system). You will also be notified in the label about who will carry out the delivery during the final leg of the shipment; be it UPS or USPS.

Pros & Cons of using UPS SurePost

Wouldn’t it be great to be able to save at least 20% off the shipping cost? The answer is, Yes! Reduced shipping costs are not the sole benefit of using SurePost. There are many  potential benefits to highlight, including the following:


  • Regular pickup options are made available: SurePost does not require out-of-the-box treatment for pickups or drop-offs. Shipments can be combined with the typical UPS pickup service as trips to the post office are not made mandate
  • Tracking of packages is made easy from the point of pickup till the item is delivered:  UPS provides its users with the ability to track packages. This is included when you utilize the SurePost service. The same reference/tracking number can be used even when USPS is handling the last leg of the delivery.
  • SurePost can be integrated with Shipping software: The key behind managing large shipments is by having SurePost integrated with the Shipping software you use.
  • Manages the expensive section of the shipment: As stated above, the most expensive part of the shipment is the last/final leg where the package is delivered by U.S.P.S. This makes up 28 percent of a shipment’s total costs — nearly 1/3rd of the overall shipping cost. With the help of SurePost this high cost is taken care of and UPS has created a more cost-efficient option for sellers who ship large volumes of packages.
  • Saturday delivery is made available: With SurePost, most packages are handed over to USPS for the final leg of delivery. Delivery of packages over the weekend is made possible and is not at any additional fee as the cost for Saturday delivery is included in the service by default. This is an important benefit as weekend delivery normally balances the drawback of SurePost being a slow service.
  • Shipping to more addresses is now possible: On a regular day, UPS does not deliver to PO boxes, depending on your business, this may or may not be a sticking point. It is good to remember that since SurePost is a hybrid UPS and USPS service. The flexibility to reach more geographic locations that regular UPS services are unable to reach is one of the hidden advantages of using SurePost
  • Deliveries are made to residential addresses and packages are generally lightweight (less than 10  lbs)
  • If you are a member, you are allowed to use the “UPS My Choice” membership which will enable you to make use of the reschedule and redirect deliveries feature respectively. By doing so, upgraded packages may arrive a day earlier.
  • SurePost guarantees that the deliveries made would normally take between 2-7 days to arrive at their destination. However, that is not the case, a few users have reported that SurePost would result in an average of a 3-day delay when compared to typical UPS services. 
  • Due to the fact that packages have to be transferred from one carrier to another, the shipment sent via SurePost is generally delayed but is also the main source of a reduction in the cost. It is important to consider the benefits and drawbacks of SurePost in order to determine what is right for your business.


  • Along with the list of benefits of using SurePost, SurePost users also face a few drawbacks. Namely:
    • SurePost might take a little longer for the package to get delivered.
    • Making the last mile more efficient does slow down the delivery process slightly. The UPS team (drivers) have to pass on the package to USPS who in turn sort these packages appropriately so they get to their correct addresses respectively. Is it cost-effective? Yes. But it is a lot slower than the regular services.
