How to Complete USPS Form 1583

Because Host Locations will be receiving mail on behalf of the Members they host, they must ensure that each Member they host completes USPS Form 1853, and that an original is filed with the local Post Office branch.

Filling Out Form 1583

In general, the form is broken down into three sections: the CMRA (i.e., “Host Location”) information, the Applicant (i.e., “Member”) information, and the Member’s business information.

Most items are self-explanatory.  Here are some hints:

  • Box 2: Write the full Member name (i.e., the law firm name)  that the Host Location will be receiving mail for.
  • Box 3: Write the Host Location address, including the suite number.
  • Box 4: This information is generally filled out by the Host Location. It simply shows who the Member is authorizing for mail delivery and the Host Location address.
  • Box 5: Member signs here to authorize the Host Location to receive restricted-delivery mail on its behalf.
  • Boxes 6 & 7: Indicate the person individual who is applying for this mailbox. Normally, this is the same as the person who is receiving mail for this mailbox (see box 2). Be sure to include a phone number where you can be reached.
  • Box 8: Member must write down the two IDs that it will use to prove their identity and the ID numbers. One must be a photo ID. You can find a list of acceptable IDs at the end of this article.
  • Boxes 10a – 10e: Add Member’s business contact information. You may use your business mailing address or registered agent address as well. Member can use their home address if none other is available.
  • Box 11: Put “legal services” or “law firm” etc.
  • Box 12: Enter each member or employee who will receive mail here. Although names must have verifiable identification, a separate Form 1583 is not required for each employee.
  • Box 16: Sign the form.

Notarize Form 1583

The Member needs to get the form notarized, and the notary should sign box 15 of the form or provide a certification on a separate paper.

Notary tip: Most law firms have someone on staff that is a notary.  Otherwise, most banks offer free notary service to their existing customers. You may want to check with your bank first.  

Sending the Form 1583 Documents to Post Office

Member will give fully completed, signed and notarized form to Host Location.  Host Location will make and keep a copy, and send the original copy (NOT a photocopy) to the US Post Office.
