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.

The WooCommerce Royal Mail shipping plugin allows you offer Royal Mail shipping rates to customers without the need for an API, as Royal Mail does not provide a public API. To use this plugin, your store must use GBP currency and have the United Kingdom as the base country, and your products need to be set up with weights and shipping dimensions. This plugin primarily works with mm and g, but other units are converted automatically!
