Commercial Mail Receiving Agency notice

100 Acre Mail operates as a Commercial Mail Receiving Agency (CMRA). Clients must complete the required USPS authorization process before receiving mail through the service.

Form 1583 and identification

Each mailbox client must complete USPS Form 1583 and provide required identification. Two forms of acceptable identification may be required. Business clients may also need to provide business/entity documentation and authorized representative information.

Service activation

Mailbox service, mail scanning, forwarding, pickup, and portal access may be delayed or restricted until compliance documents are received, reviewed, and approved.

Compliance Document Upload

Verified clients may upload USPS Form 1583, primary ID, secondary ID, and business/entity documents through the secure client portal for staff review. Uploading a document does not mean it has been approved; staff must review and mark compliance status.
