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.

We recommend using this extension in combination with our Stamps.com extension (separate purchase), which creates shipping labels based on real-time rates from USPS.

Other features:

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