How do I become a Contract Postal Unit Supplier?

These units provide full service retail products and services to postal customers at U.S. Postal Service prices. They are housed within a supplier facility and are operated and managed by supplier employees.

Retailers that participate in the Contract Postal Unit program are provided USPS branding rights and signage. A build-out that meets postal regulations is required. Suppliers are limited to selling only USPS products and services. Contract Postal Unit suppliers are compensated based on performance. Operating a Contract Postal Unit increases foot traffic and provides additional customer convenience. Placement of a CPU is driven by the need for additional Postal Service access points in a community. Local postal resources determine this need.
