The United States Postal Service is discontinuing the United States Postal Service Corporate Account (USPSCA) method of payment.  In January 2023 we will begin closing inactive accounts and will be closing all USPSCA accounts by July 1, 2023.

External customers who currently use USPSCA as a payment method are encouraged to switch to an available alternative.  Alternative methods of payment may include Click-N-Ship (CNS), Electronic Verification System (eVS), ePostage, PC Postage or Metered Postage.

Customers should contact their Sales Account/BSN Representative, if assigned one, or their local Post Office, for assistance with USPS Product/Service account migration.

Any accounts with a balance can request a refund through the resources listed below:

• Customers should contact the Mailing & Shipping Solutions Center (MSSC) at  MSSC@usps.gov for assistance.
• Please include a request for refund with a signed authorization on company letterhead,
  EMCA #, business name and location.

Accounts with a negative balance after July 1, 2023, will be sent to Accounts Receivable for collection. Customers can make payments to negative accounts by contacting the MSSC using the link above.

For questions regarding the elimination of corporate accounts, please email ShippingServices@usps.gov.
