A Commercial Mail Receiving Agency, or CMRA, gives you a credible, professional mailing address for your LLC while also putting some separation between your home address and your business address. Below we’ll discuss what to know about CMRAs (including the benefits) and how to hire a CMRA of your own.

What is a Commercial Mail Receiving Agency?

A CMRA is a private business (like us) that receives mail from the U.S. Postal Service and other carriers on behalf of a third party (like you). CMRAs can accept mail on behalf of both businesses and individuals.

At Rocky Mountain Registered Agent, we’ll scan your mail digitally and upload it to your secure online account. We also filter your junk mail and shred it before you even know about it. You can pick from one of three plans, all of which include a unique suite number:

Why is a CMRA better than a P.O. Box?


P.O. Boxes may seem like a good option, but that still means you have to go to your mailbox and check your mail. Here’s some other reasons why a CMRA can be a better option.

Professionalism: With a CMRA, you get an office address rather than a P.O. Box.

Security and Privacy: Want to run a business but don’t want your home address to be your business address? Getting a CMRA means you can maintain more privacy and security. It’s also a good idea to receive your business mail at a separate address from your personal mail, as it lessens the chances of them getting mixed up.

Stability: A CMRA gives you a permanent address where you can receive your mail, regardless of if you work at multiple locations.

A Wider Range ofOptions: A CMRA is authorized to accept mail from private carriers like UPS and FedEx, not just USPS. A CMRA also offers digital mail scanning and storage, which is simpler than finding a place to store physical business mail you get.

How to Sign Up for a CMRA

First, choose from our standard or premium mail service. Or if you want unlimited mail scanning, go up a tier and get a virtual fofice.

Once you’ve signed up for a service, you’ll need to log into your online account and fill out Form 1583. This is a requirement from the U.S. Postal Service, so make sure not to skip this part.

USPS uses Form 1583 to verify that you’re receiving your mail through a licensed and registered CMRA. It’s designed to protect you, even if it does mean that you have to fill out additional paperwork.

For Form 1583, you’ll need to provide your name, residential street address, a copy of your photo ID, proof of your address, and a digital signature.

For photo ID, provide one of the following:

Don’t try presenting your Social Security card, credit card, birth certificate or concealed carry permit, as they won’t be accepted.

For proof of address, provide one of the following:
