EasyPost USPS Integrations

Ship smarter with USPS

Shipping costs are rising and efficiency matters more than ever. As the largest residential carrier in the U.S., the United States Postal Service (USPS) is one of the most reliable and affordable carriers for many businesses.

EasyPost makes it simple to connect with USPS, offering two integration paths: PC Postage, where you'll leverage the EasyPost Wallet Carrier account, or USPS Ship where you can bring your own account credentials.
