Invalid Express Mail Corporate Account Numbers

This listing should be provided to Contract Postal Units and used by acceptance clerks in non-POS locations with­out intranet access to validate an Express Mail Corporate Account (EMCA) number online. For all other locations, online EMCA validation is preferred. The online validation process is outlined in the EMCA Validation SOP on the Retail webpage. This list supersedes all previous notices, which must be recycled. Acceptance clerks must not accept Express Mail^® shipments bearing an invalid EMCA number in the “Payment by Account” or “Agreement Num­ber” section of the Express Mail label or form.

Note: The first 6 digits of a 9-digit Custom Designed Ser­vice and Next Day Pickup Agreement make up the Corporate Account Number.
