USPS Form 1583: what it is and why every virtual mailbox requires it

Setting up a virtual mailbox sounds simple. You choose a provider, pick an address, and start receiving mail digitally.

Then you hit an unexpected step: USPS Form 1583.

Many people pause here. Why do you need to fill out a form and even get it notarized just to receive mail? It can feel excessive, especially if you’re used to quick online sign-ups.

In reality, this step is standard. Every legitimate mail forwarding or virtual mailbox service in the U.S. is required to collect this form before handling your mail.

This guide explains what USPS Form 1583 is, why it exists, and how to complete it correctly so you can move forward without delays.

What is USPS Form 1583?

USPS Form 1583 is used to authorize a third party to receive and handle mail on your behalf. If you register for a virtual mailbox or mail forwarding service, you do not receive the mail directly. Mailbox centers receive, scan, store, or forward your mail. They need your permission to do this, and Form 1583 is how you grant it.

All Commercial Mail Receiving Agencies (CMRAs), including private mailboxes, are required to display this notice. A CMRA is a business approved by the U.S. Postal Service to receive mail and other commercial matter on behalf of its customers. These businesses operate throughout the USPS network.

You should also be aware that a provider cannot legally accept your mail unless you have a completed Form 1583.

Important: Form 1583 does not set up automatic mail forwarding with USPS. It only authorizes a specific CMRA to receive and handle mail sent to that particular address.

Why Form 1583 is required

In the U.S., handling mail is regulated. To prevent fraudulent practices and assist in the battle against identity theft, the USPS requires that anyone who receives mail on behalf of others have access to the information necessary to verify a customer's identity.

This process is similar to how banks authenticate your identity prior to any transactions. Essentially, you must verify your identity and obtain explicit consent before allowing a service to act on your behalf.

However, all legitimate virtual mailbox providers need Form 1583 to set up a mail service address for you. If a mail forwarding provider that you are considering does not mention the need to provide Form 1583 to the Post Office, you should be on high alert.

Who needs to fill out Form 1583?

Form 1583 applies to anyone using a service that receives mail on their behalf.

This includes:

• Individuals using mail forwarding services
• Digital nomads and expats
• Full-time RVers
• Remote workers without a fixed address
• Businesses using virtual offices or mailing addresses

Whether you’re living abroad, traveling full-time, or simply want to manage your mail digitally, you’ll need to complete this form.

What information is required on Form 1583

The form itself is straightforward, but accuracy matters.

You’ll be asked to provide:

• Your full legal name
• Your current residential address
• The address of the mail forwarding provider (CMRA)
• Contact information

You’ll also need to include identification details and sign the form in the presence of a notary.

Even though the form is simple, any mistakes or inconsistencies can delay your mailbox setup.

Accepted forms of ID

To complete Form 1583, you must provide two forms of identification.

Typically, this includes:

Primary ID (photo ID):

• Passport
• Driver’s license
• Government-issued ID

Secondary ID:

• Utility bill
• Bank statement
• Lease agreement
• Insurance document

The IDs must be valid and clearly show your name. In some cases, they may also need to match the address you provide on the form.

Providers may have slightly different requirements, so it’s always worth checking their guidelines before submitting.

Why is notarization required?

What is the notarization requirement on Form 1583?

A notary is a state-commissioned official who verifies your identity and witnesses your signature. Notarization formalizes your authorization and helps protect against fraud.

Notarization is also a compliance measure that has helped prevent fraud. No one can set up a mailbox in your name without your knowledge. While this may seem irritating, this is a normal process and takes a matter of minutes.

How to complete Form 1583 (step-by-step)

Filling out Form 1583 is straightforward if you follow the right steps.

1. Get the form from your provider

Virtual mailbox services will provide you with a pre-filled form, or one that is already partially completed. If this is the case, then make sure that the information provided is correct.

2. Fill in your personal information

Ensure all information is provided accurately and exactly as found on personal identification documents. This must include a full legal name and complete street address.

3. Confirm your provider details

The form must include the name and address of the mail forwarding company. These details MUST be correct.

4. Prepare your identification

Gather your two forms of ID and ensure they are valid and clearly readable.

5. Get the form notarised

Once completed, take a copy of the form to a notary or utilize an online notarization service. You will need to sign the form in the presence of the notary.

6. Submit the form

Send the notarized form and a copy of your ID to your provider. Once approved, you can have your mailbox activated.

Can you complete Form 1583 online?

Yes, in many cases you can complete the process online.

Several providers support remote online notarization (RON), which allows you to verify your identity and sign the form digitally.

This is especially useful for expats and travelers who may not have easy access to a local notary.

However, not all providers support this option, so it’s important to check before starting the process.

Common mistakes to avoid

Most delays with Form 1583 come from simple errors.

Here are the most common mistakes:

• Submitting expired or invalid ID
• Using names that don’t match your documents
• Providing an incorrect or outdated address
• Forgetting to notarise the form
• Sending unclear or low-quality scans

Taking a few extra minutes to double-check everything can save you time later.

What happens after you submit Form 1583

Once your provider receives your form, they will review your information and verify your identity.

If everything is correct, your mailbox will be activated. This usually takes a few days, depending on the provider.

If there are issues, you may be asked to resubmit documents or correct errors.

After approval, you can start receiving, scanning, and forwarding your mail as planned.

Is Form 1583 safe?

It’s normal to have concerns about sharing personal information.

Reputable mail forwarding providers take data security seriously. They use encryption and secure systems to store your information and comply with privacy regulations.

That said, it’s important to choose a trusted provider. Look for companies with clear privacy policies and established reputations.

Form 1583 vs legal residence

One important point to understand is that Form 1583 does not establish legal residence.

It simply authorizes a provider to receive your mail.

This means that having a virtual mailbox alone may not be enough for:

• Opening certain bank accounts
• Getting a driver’s license
• Establishing tax residency

For those purposes, you may need a compliant residential address and additional documentation.
