Get real-time rates from the largest shipping network in the US

Show your customers accurate shipping rates automatically with our integration for USPS, the largest delivery network in United States.

Your store must use US Dollars for its currency and the United States, US Virgin Islands or Puerto Rico as the base country. It works with inches (in) and pounds (lbs), but other units can be converted automatically.

USPS calculates quotes worldwide.

Domestic	International
First Class Flat Rate Priority Mail Priority Mail Express Standard Post Media Mail Library Mail	First Class Mail® International Letters and Envelopes Global Express Guaranteed (GXG) Priority Mail International Priority Mail International Flat Rate International Postcards

We recommend using this extension in combination with our free service WooCommerce Shipping, which creates discounted shipping labels right from your WooCommerce dashboard.

Other features:

Enable/disable, edit the names of, and add costs to services
Pack items individually or using the built in box packer

The box packer is volume based. This provides good results in most cases but are never be as accurate as a real person packing a box (see BIN Packing Problem). Therefore, it is important to understand that packing results are as accurate as possible, and any anomalies should be acceptable.

This is absolute garbage. I have signed up with USPS, got all the credentials, still not working. It is a mess and there is no support from anyone, Woo commerce and USPS do not have their crap together on this rollout. It is NOT easy to use. STAY AWAY, I will be working at trying to get my money back. Spent 3 hours on it and still feel like I am not a inch closer to having my website show shipping options.

This app does not work with the new USPS APIs. There is no support from WOO and the USPS doesnt care about trying to get you REST APIs for WOO. Its time to look elsewhere WOO is a money grab of subpar extensions.

Absolutely a mess. The documentation for changing the API is not accurate. The Post Office offers no support. To set this up requires about 25 steps and endless loops of delegating BSA, creating CRIDs, payments, enrollments, etc. It is exhausting! Dump this garbage and find another solution.

If you’re still interested, please reply there with where you’re getting stuck (and which part of our docs didn’t match what you saw) so we can help and make sure the documentation is updated.

I have been using this plug in for at least 3 or 4 years. I am satisfied with how it has worked including the new API update. Keep it up
