How to Get USPS CRD Access: The CMRA Registration Steps Nobody Explains

How to Get USPS CRD Access

The registration steps between "I filed my 1583-A" and "I can actually upload my forms"

Here is a conversation we have with mailbox store owners all the time. It usually goes something like this:

"I haven't ever done the USPS CRD stuff. No idea what I gotta do."

"I've been trying to find where I submit things... can't find it."

If that sounds familiar, you are not behind, and you are not missing something obvious. The USPS Customer Registration Database (CRD) is a government system, and like most government systems, it does not exactly walk you through onboarding. There is no big "Sign Up for CRD" button. Access flows through your local Post Office and the USPS Business Customer Gateway, and if any step in that chain stalls, you end up exactly where the operator above was: obligated to upload Form 1583 records with no visible place to upload them.

This guide covers the full path — from PS Form 1583-A to a working CRD login — plus what to do when the invitation never shows up.

If you are still fuzzy on what CRD actually is, start with our primer: What Is CRD?

The Short Version: Three Steps to CRD Access

Getting into CRD is a three-step handoff between you, your postmaster, and the USPS Business Customer Gateway:

Register as a CMRA with your local postmaster by submitting PS Form 1583-A (Application to Act as a Commercial Mail Receiving Agency).
Wait for approval and the USPS invitation. Once your 1583-A is approved and your CMRA is registered, USPS sends you an invitation with enrollment instructions for the CRD.
Use those instructions to enroll through the USPS Business Customer Gateway at gateway.usps.com, where the CRD tool lives.

That is the whole map. The friction is that each step depends on the one before it — and step two happens on the Post Office's side, where you cannot see it. Let's walk through each step in detail.

Step 1: Register With Your Postmaster (PS Form 1583-A)

Before USPS will give you access to anything, your business has to be registered as a Commercial Mail Receiving Agency (CMRA). That registration happens at your local Post Office, not online.

The form for this is PS Form 1583-A, Application to Act as a Commercial Mail Receiving Agency. This is the store's form — do not confuse it with PS Form 1583, which is the form your customers complete to authorize you to receive their mail. (More on how those work together in How PMBs and USPS Form 1583 Work Together.)

You submit the completed 1583-A to the postmaster at the Post Office responsible for delivery to your store's address. The postmaster reviews and signs off on your application, and your CMRA gets registered with USPS.

Two practical tips at this stage:

Make sure the contact email on your application is one you actually check. The CRD invitation in the next step depends on USPS being able to reach you.
Keep a copy of your signed 1583-A and note the date you submitted it. If you have to follow up later, "I submitted it on this date to this office" gets you much further than "a while ago."

Step 2: The Postmaster Approves — and USPS Sends an Invitation

This is the step that trips up the most operators, because it is the one where you have nothing to do — and no visibility.

Once your postmaster approves your 1583-A and your CMRA registration is processed, USPS sends you an invitation with instructions to enroll in the CRD. That invitation is your golden ticket: it contains the enrollment instructions you need to set up your access.

Here is the problem: many operators never connect these dots. They submit the 1583-A, the postmaster signs off, mail service begins, and everyone moves on. Months later, the operator goes looking for "the place to upload 1583s," finds nothing, and assumes they are missing a link somewhere on usps.com. They are not. They are missing the invitation.

What to do if you never received an invitation

If you have already submitted your 1583-A and the postmaster signed off, but no invitation ever arrived:

Check the email account associated with your CMRA application, including spam and junk folders. The invitation is easy to miss.
Call or visit the Post Office where you submitted your 1583-A. Ask them to confirm that your CMRA registration was fully processed and that the CRD invitation was issued. "Signed by the postmaster" and "processed into the USPS system" are not always the same moment.
Ask them to re-send or re-issue the invitation if it was never generated or went to a wrong or outdated email address.

Do not wait on this. Your CRD obligations — entering approved Form 1583s, uploading customer IDs, recording closures, and quarterly certification — exist whether or not your access is set up. Every week without access is a week of compliance backlog piling up.

Step 3: Enroll Through the USPS Business Customer Gateway

The CRD is not a standalone website with its own login page. It is accessed through the USPS Business Customer Gateway (BCG) — the same portal USPS uses for its other business services.

Once your invitation arrives, follow its enrollment instructions at the Business Customer Gateway sign-in page:

https://gateway.usps.com/eAdmin/view/signin

If you do not already have a Business Customer Gateway account, you will create one as part of enrollment. If you do have one (for example, from other USPS business services), you will be adding CRD access to it per the instructions in your invitation.

Once enrollment is complete, the CRD becomes available to you through the Gateway. That is where you will:

Enter the information from each approved customer Form 1583
Upload clear, legible images of customer identification documents
Record termination dates when PMBs close
Complete your quarterly certification (due January 15, April 15, July 15, and October 15)

"Where Do I Submit Things?" — Answering the Question Directly

Because this is the question that sends most operators searching in the first place, here is the direct answer:

You submit your customer Form 1583 records inside the CRD, which you access through the USPS Business Customer Gateway. You do not email them to USPS. You do not mail them to the postmaster. You do not upload them anywhere on the public usps.com site.

If you cannot find where to submit your records, it is almost always because one of the three steps above is incomplete:

Symptom	Likely gap
No idea where to even start	Step 1 — your 1583-A may not be submitted or approved yet
1583-A approved, but no login anywhere	Step 2 — the CRD invitation was never received; contact your Post Office
Have an invitation, but lost or expired	Step 2 — ask your Post Office to re-issue it
Have a BCG account, but no CRD access	Step 3 — enrollment per the invitation instructions was never completed

You Have Access — Now Build the Habit

Getting into CRD is the one-time hurdle. Staying current in CRD is the ongoing discipline — and it is where the real compliance risk lives.

Once your access works, your first session should focus on catching up: enter every approved Form 1583 currently on file, upload the ID images, and record termination dates for any mailboxes that closed while you were waiting on access. Then put the quarterly certification deadlines on your calendar.

From there, the operators who stay out of trouble are the ones who treat CRD as an event-driven habit — every new approval, ID replacement, and closure creates a task — rather than a quarterly emergency. We wrote a full operating playbook for that: Do you CRD?

Innbocks is built around exactly that workflow. It cannot register your CMRA for you — the 1583-A and the CRD enrollment are yours to own — but once you are in, it turns every compliance event into a tracked task, keeps evidence attached to the customer record, and shows you exactly what is outstanding before each certification deadline. The government system tells you what is required; Innbocks makes sure nothing required gets forgotten.

Quick Reference: The CRD Access Checklist

Complete PS Form 1583-A and submit it to your local postmaster.
Confirm the postmaster has approved it and your CMRA registration is processed.
Watch for the USPS invitation with CRD enrollment instructions (check spam; confirm your email on file).
No invitation? Call or visit your Post Office and ask them to confirm registration and re-issue the invitation.
Follow the invitation instructions to enroll at the USPS Business Customer Gateway.
Log in, catch up on existing Form 1583 records, and calendar the quarterly certification dates.
