USPS FORM 1583 | Upload Completed Form


Anyone who wants to rent a PO box, postal mailbox or virtual mailbox in the United States must fill out the USPS Form 1583. This article will help you understand what USPS Form 1583 is for and how to fill it out properly for your mail forwarding service or PO box rental. Without a USPS form 1583, you are subject to US mail fines and felony prosecution. Do not sign up with any company that does not require this form!

What is USPS Form 1583?

In the United States, the U.S. Postal Service regulates how mail can be received and handled. USPS also dictates required procedures for commercial mail receiving agents (CMRAs) like us to follow. The USPS Form 1583 is used to authorize a CMRA to receive mail on the customer’s behalf.  It also ensures that a responsible party is linked to the mailbox.

Filling Out Form 1583

In general, the form is broken down into three sections: the CMRA information, the mailbox and owner information, and optionally the business information.

PMB Information (Box 1)

This information is generally filled out by the CMRA, so you do not need to concern yourself with most of this.

CMRA Information (Box 2)

This box shows shows where your mail is being delivered. If you use our 800 Fifth Avenue address, the following this information would in Box 2:

800 Fifth Ave., Ste. 101-800

Seattle, WA 98104-3102

If you use our Ballard address, the Ballard address will go here, including your assigned suite number:

5608 17th Ave. NW, Ste. [INSERT ASSIGNED BOX NUMBER]

Seattle, WA 98107-5232

Mailbox Owner and Optional Business Information

This is the information that you need to fill out. Most items are self-explanatory.

  • Box 3: If you opened the box for your business or non-profit organization, check "Business/Organization" use. Otherwise, check, "Residential/Personal Use."

  • Box 4: Write the full primary person's name that this mailbox will be receiving for (your name), your telephone number, and your home address. Even if you are applying on behalf of an entity, the person who is making the application must list their name and home address here. This address must match a document you provide with respect to box 11.

  • Box 5: If you want to authorize another person to pick up mail, please insert their information in box 5.

  • Box 6: If you are using the Ballard address do not fill out this section. If you are using the 800 Fifth Avenue address, all of your mail is routed to our main office in Ballard for processing. So, if you are using the 800 Fifth Avenue address you should insert the Ballard office information here:

    • 5608 17th Ave. NW

      Tel: 206-913-2467

  • Box 7: Insert information for your business here, if applicable. Skip this section if this is a residential/personal mailbox. If we are providing your business's primary address, you can insert your address with us here. Otherwise, insert your your business's primary street address.

  • Box 8: This is the information from the photo identification you are providing.

  • Box 9: This is a document verifying the applicant's address. It must be one of the documents from the list. A driver's license can only be used here if you are using a different document as your photo id in Box 8 (for example, a passport).

  • Box 10: If you also authorized another person to pick up your mail, their identification information must be entered here. Otherwise, leave blank.

  • Box 11: If you authorized another person to pick up your mail, their address verification document information goes here. It cannot be a driver's license unless they used a different identification document in Box 10. If you did not authorize an additional person to pick up your mail, leave blank.

  • Boxes 12: If you have a business and want additional persons to receive mail at this address affiliated with your company, list those persons here. inCitySpace permits one additional name to be listed here, in addition to the Applicant. If you wish to add more names, please contact us for information about the associated fees.

  • Box 13: Sign the form in the presence of a notary or bring it into our office and sign it in the presence of one of our employees at our Ballard office.

  • Box 14: The witness can be a notary or our employee (if you signed it at our office).

Notarize Form 1583

Normally, if you sign this form in person in front of a authorized staff member at your mailing address location, you do not need to have the form notarized. However, as you most likely won't be able to do so, you need to provide proof of identity through a notary. The notary should sign box 15 and place a notary seal on the Form 1583 itself. Alternatively, a separate notary certificate of acknowledgement can be attached. 

Notaries can be found almost everywhere. Courthouses and banks normally have an in-house notary who will serve you. You can also search for "notary directory" on any search engine to find a local notary. The cost is usually less than $20.

We also accept online notarized documents from notary services.  We recommend using Notarycam.  Fees are a little higher than in-person notaries, but you can notarize the document from anywhere as long as you have a webcam for video chat.

Free notary tip: 

  • Some banks offer free notary service to their existing customers. You may want to check with your bank first.

International/Non-U.S. Residents

If you live overseas, you may have difficulty finding a notary. Banks and embassies normally provide notary service. Both U.S. and non-U.S. notary seals are accepted. If finding a notary proves impossible, you can go through a lawyer or bank official who can sign or stamp an official seal on the form. Government seals and apostilles (ie. police) are also acceptable.

Notarycam will also notarize documents with international IDs.  You can notarize the documents as long as you have a webcam.
