What Is USPS Form 1583?

USPS Form 1583 is a document that must be completed by any individual or organization that wants to receive mail at a USPS post office box. The form is used to verify an applicant’s identity and give permission for the USPS to deliver mail to a designated P.O. box.

Purpose of USPS Form 1583

Anyone renting a P.O. box through the post office or from an approved third-party business location must fill out USPS Form 1583. USPS keeps these files to keep track of the identity of individuals using an address in case somebody uses that address in criminal activities.

The postal service is responsible for enforcing regulations regarding mail handling and delivery. The agency sets regulations and policies for commercial mail receiving agencies or CMRAs.

USPS Form 1583 allows commercial mail-receiving agencies to receive someone else’s mail. Suppose you want to receive bulk mail for your business at a postal facility. In that case, you can designate an agency as the one that will handle all of your commercial mail.

USPS Form 1583 also ensures that a responsible party is linked to each mailbox. That way, your mail is always safe and secure. In other words, completing Form 1583 is an essential step in establishing a P.O. box.

CMRA Explained

CMRAs are involved in the mail and parcel delivery industries and printing. Coworking facilities and private companies help individuals and businesses run their mailing operations separately from the national postal administration. 

CMRAs can receive mail items that exceed standard size restrictions. Businesses commonly use this type of mailing address for several reasons:

  • CMRAs reduce the time and effort needed for administrative tasks, leading to increased productivity.
  • Virtual office solutions can help businesses lower their overhead expenses.
  • CMRAs help to automate and archive the handling of physical mail.
  • Shipping is quick and affordable.

Why Do You Need to Complete a USPS 1583?

  • Box 5: Sign this box to authorize your CMRA to collect restricted-delivery mail for you.
  • Boxes 6 and 7: List the name of the person requesting this mailbox. The mailbox owner must be an individual, even if the account is for a company.

  • Box 8: List two pieces of acceptable IDs and the numbers for each.
  • Box 16: Sign the form before a notary public is required. You can also sign digitally.

  • Box 11: You can describe your company’s type of business by listing services or products you provide, such as “market research” or “consumer products.”
  • Box 12: Add users who will receive mail here. All names of the users that were listed must have verifiable identification. Still, USPS does not require you to file a  separate form for each user unless requested.

What Do You Do After You Complete a USPS 1583?

You can also have mail forwarded by submitting a change of address form to the post office. Once you do this, you’ll be able to receive notifications when your mail arrives, eliminating the hassle of sorting through junk mail again.

Having USPS 1583 Notarized Online or in Person

Where Do You Send Your USPS Form 1583?

  3. Via fax: Forward the signed form and a copy of your two IDs to your CMRA. This is the least preferred method of sending documents because it often fails to capture information accurately.

Who Signs the Form?

Generally, there are three people required to sign the form:

  • Yourself
  • Your CMRA
  • Your Notary

The USPS form will also be signed by whoever approves it.

What if You’re Not a U.S. Resident?

Finding a notary may be difficult if you live outside the United States. However, banks and courthouses often perform notary services. Both U.S. and non-U.S. notary seals are acceptable.

If you can’t find a notary, you can go through a lawyer or bank official who will sign or stamp an official seal on the form. Police and government seals are two examples of acceptable notaries.

Change of Address

For your CMRA to receive your mail, you must have it forwarded to their business address. The steps involved in this process are straightforward and can be completed by choosing one of the following options:

  1. Go to the USPS website and fill out a change of address form online. For easier navigation, here is a link to the website.

Virtual Mailboxes and the USPS Form 1583

USPS Form 1583 is an essential first step for setting up a virtual mailbox in California, Texas, Florida, New York, Pennsylvania, and other states including Alaska and Hawaii. For this reason, some CMRAs have made it easy for domestic and international applicants to get their documents notarized from their computers. Ensure that you have a webcam and can present appropriate identification.

Is Your Mailbox Through the U.S. Postal Service or a Private Company?

Your mailbox is through a private company. The CMRA is a private company that has been given the right to manage these services. 

However, because of the CMRAs’ role, they are also responsible for ensuring that all necessary forms and regulations are in place and the proper required forms of acceptable identification are presented.

How Many People Can Use the Same Account or Mailbox?

Individuals and companies that rent mailboxes must be mentioned in the address provided to USPS by mailbox renters. If it is a domestic partnership, the arrangements can vary.

Note that each person receiving mail would have to fill out a form. It’s always wise to consult with an attorney regarding these matters.

How Does HIPAA Security Work With a Virtual Mailbox?

While some operators are HIPAA compliant, others are not. If that is important, check with your CMRA and the company’s policies before starting an account.

The Health Insurance Portability and Accountability Act of 1996 (HIPAA) provides data privacy and security regulations to protect sensitive patient health information from disclosure without the patient’s consent.
