USPS shipping for your online store
Shipi connects your store to the new USPS APIs using your own USPS business account. Show Commercial or Retail prices at checkout, print labels for Ground Advantage, Priority Mail and Priority Mail Express, and send international parcels with the customs form built in.

Common questions
What do I need from USPS?
An app on the USPS Developer Portal (consumer key and secret), your CRID and Mailer ID, and an Enterprise Payment System (EPS) account that labels are paid from. Our team can walk you through the USPS setup if you have not done it before.
Commercial or Retail prices?
Choose either in Shipi. Commercial prices are usually lower and need an eligible USPS business account.
Do I need my own USPS account?
Yes. You open a business account with USPS and enter its credentials in Shipi (USPS consumer key and secret, CRID, Mailer ID and EPS account number). You keep your negotiated rates and pay Shipi only for the software. If you get stuck on the credential step, our team will set it up with you.
Can I use USPS alongside other carriers?
Yes. Add as many carriers as you need to one Shipi account and choose per order, or set shipping rules that decide which options appear at checkout.
Which store platforms does this work with?
Any store you connect to Shipi: WooCommerce, Shopify, Wix, BigCommerce, OpenCart and PrestaShop. The carrier setup is the same on every platform.
