You have installed WooCommerce USPS Shipping Plugin with Print Label, but you are not getting expected output regarding RATES or PRINT LABELS? Well, setting up of a plugin for your WooCommerce can be confusing at times. If you forget to check one option, you may not get shipping rates at all. You must have also come across situations when correct shipping rates are not shown or the free delivery option is not available to the customers. In any such case, you may end up losing your valuable customers. So, we’ll discuss troubleshooting WooCoommerce USPS Shipping Plugin with Print Label in the article.
Troubleshooting for not Getting Rates at All
If you are not getting rates at all, then there might be some reasons for not fetching real-time shipping rates from USPS APIs. The list of reasons is as given below:
- Enable Shipping: That sounds bit trivial. But sometimes we forget to select Enable shipping checkbox. By default, Enable Shipping is disabled. So this should be your first check. You must enable shipping at two places. You should select the checkbox at WooCommerce Settings as shown below:
Or you should also select the checkbox at USPS Plugin Settings as shown below:
- Weight and Dimensions: USPS shipping carrier uses the weight and the dimensions of your product (Length, Width & Height) to calculate the shipping cost (besides using the origin and destination address). So make sure that you enter the Weight and the Dimension of your product in Product Settings as shown below:
- Fallback field Check: Make Sure you enter a numeric value in the filed or keep the Fallback field empty.The Fallback field is as shown below:
Note: Do not enter text in Fallback field.
- Enable Flat rate or API rates: You must enable either Flat rates or API rates(as shown in the below screenshot) to get shipping options on cart/checkout page.
- Core WooCommerce Shipping Options: As you know the Flat Rate, Local Pickup, and Free Delivery are available in the Core Shipping Options of WooCommerce. You should ensure that:
- You have right countries specified in the Zones. And if you are shipping to districts, make sure you enter the specific Zip Code in the box provided. In case you don’t do that, you might be showing shipping rates contrasting to USPS. For example, if you want free shipping for your origin state, and you have not mentioned it here, your customers will see USPS rates.
- Make sure you enable the specific shipping method as shown in the image below. These options are shown on the cart/checkout page only if you enable them here.
As soon as you execute these settings, you have all chances to get a shipping rate. Still, if no shipping rates are returned, it’s time to enable Debug mode. Debug mode helps you to find the exact reason for not getting a shipping rate or getting a specific shipping rate.
If you have done the above basic checks and still not getting rates, then you must enable debug mode to get exact reason for not getting rates.
If you are not getting proper rates( lesser or higher than expected), not getting all the available shipping options, not getting rates at all or not getting Print Labels, then you enable Debug option to find error(s). You can also see the warning(s) by WooCommerce USPS Shipping Plugin with Print Label.
By enabling debug mode, you can trace issue using log. You can see information about debugging at the top of Cart and Checkout page. Select Debug checkbox in USPS Plugin Settings to enable debug mode as shown below:
After enabling debug mode, add a product to cart. Go to the checkout page to see debugging information. Ensure that you have entered a proper shipping address. If you are not getting rates at all, then you need to check the response sent by USPS to know the exact reason for not showing the rates. Two cases are explained in the below section.
- Sender Address Error: If you have not entered an Origin Zipcode, no shipping rates will be shown. Your customer will be shown the following message on the cart page.
The debug message log, shows the error message as below:
- Shipping Address Error: When any customer enters an incorrect destination Zipcode, the plugin shows no shipping rates. He/she will find an error message as shown below. This happens when you choose the option of ‘Show Rates when Destination Zip is Available’. Rather you can choose ‘Show rates wherever available’ and let you customer checkout as you can edit the billing address at any point in time now. From debug response below, you can clearly make out that postal code is not correct. So correct it by clicking on Calculate Shipping in Cart/Checkout page as shown below:
- Authentication Error: In Case, entered User ID is not correct, then USPS does not display the rates. You are shown the message as shown below:
From this response, you can clearly make out that authorization is a problem. So you can enter the correct User ID in USPS Settings page as shown below:

Troubleshooting for Print Labels
If you are not able to print labels, then it could be because of the following reasons:
- Product Existence: Sometimes you might end up trying to print a label for the product which is not available in the shop. So to avoid a failed try at print labels for such products, you should check if the product still exists in your shop or not.
- Weight and Dimensions: While printing labels, USPS requires the weight and dimensions to calculate shipping cost. So you should make sure that you have properly set the Weight and Dimensions of your products.
- Service Eligibility: Select a valid service for your shipment from the Preferred Service drop-down list (shown in the screenshot below). If the selected service is not available for the particular location/product, you will get the error about service eligibility at the top of the page.
