USPS Form 1583

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.

The CMRA Information (Box 4)

This information is generally filled out by the CMRA, so you do not need to concern yourself with most of this. It simply shows to whom you are authorizing mail delivery.

Mailbox Owner and Optional Business Information

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

  • Box 1: Date

  • Box 2: Write the full primary person's name that this mailbox will be receiving for (your name).

  • Box 3: This is the full mailing address and suite number you have been assigned.

  • Box 4: This is the full mailing address and suite number you have been assigned (same as section 3). 4(a) is already filled out for you. 4(b) may include two receiving addresses if ICS is receiving mail for you at multiple locations.

  • Box 5: Sign here to authorize us to receive restricted-delivery mail on your behalf.

  • Boxes 6: Indicate the person who is applying for this mailbox. Normally, this is the same as the person who is receiving mail for this mailbox (see box 2).

  • Boxes 7: Be sure to include a phone number where you can be reached as well as your current mailing address (your home address or primary residence).

  • Box 8: Write down the two IDs that you will use to proof your 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 9-14: See below.

  • Boxes 15: Your signature.

  • Box 16: Sign the form in the presence of a notary.

Optional Business Information

If you are linking a business to your mailbox, fill out boxes 9–14. Most boxes are self-explanatory except for a few that are clarified below:

  • Boxes 10a - 10e: Add your business contact information. You may use your business mailing address or registered agent address as well. Use your home address if it is a home-based business. This information is only for VPM and USPS and is not available to others.

  • Box 11: Indicate what product(s) or service(s) your business provides, such as “market research,” “consumer products,” “clothing,” etc.

  • Box 12: Enter each member or employee who will receive mail here. Although names must have verifiable identification, we do not require you to provide a separate Form 1583 for each employee unless requested by us.

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.

  • If you are really in a pinch and need to get your form pushed through quick, fill out your form without notarization and send us copies of your IDs along with a photo of yourself holding those same IDs. The IDs must be legible in the selfies you send us. We will waive the notarization portion for you if all the information is there.

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 (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.
