Welcome to the USPS Supplier Registration site. All suppliers interested in doing business with the Postal Service must register their organization in our Supplier Registration eSourcing system.
1. Suppliers should first search beta.SAM.gov (http://beta.SAM.gov) to learn about U.S. Postal Service solicitations as well as the notice of intent to post solicitations in the USPS eSourcing application.
2. Following step #1, suppliers must complete a 2-step process to register their organization. To start the registration process, please complete the form referenced in the link below and attach in an e-mail message to eSourcing@usps.gov. Once the initial form is reviewed and approved by the Postal Service, the primary contact listed on the form will receive an e-mail containing login credentials and a link to the Coupa Supplier Portal.
3. After the supplier completes the Coupa Supplier Portal registration process, the Postal Service will review the registration entry for completeness and accuracy. The supplier will receive a final notification once the registration is approved.
Please note that your Coupa Supplier Portal username and password will be separate from your eSourcing event username and password. eSourcing event username and password will be set up if you are invited to a USPS event.
If you need additional help or have any questions, please contact the USPS eSourcing technology support team at eSourcing@usps.gov.
Thank you for your interest in partnering with the USPS. We look forward to doing business with you.
