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 FEDBIZOPPS (www.fedbizopps.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 that process, suppliers must then register their organization on the U.S. Postal Service’s eSourcing site. Access the site at: https://uspsprod.emptoris.com/
3. After completing the eSourcing registration process, the Postal Service will review the registration entry for completeness and accuracy within one business day of supplier submission. Once the entry is reviewed and approved, the supplier will be notified the same day of their login credentials, and will be able to participate in events of interest.
Suppliers are encouraged to review the below eSourcing Supplier Registration Guide prior to starting the registration process.
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.
