What is a CMRA?
A Commercial Mail Receiving Agency (CMRA) is a private business that accepts mail on behalf of others. UPS Store locations, virtual mailbox services, and many virtual office providers operate as CMRAs. They are registered with the USPS and require customers to fill out Form 1583 to authorize mail receipt.
Not all CMRAs are the same. The key difference is how the USPS classifies the address: residential or commercial. This classification, called the Residential Delivery Indicator (RDI), directly affects how banks view the address.
Quick take: RDI status matters more than the CMRA label itself. A residential-classified CMRA often sails through bank KYC while a commercial one gets flagged.
CMRA vs PO Box: What's the Difference?
| Feature | CMRA | PO Box |
|---|---|---|
| Street address | ✅ Yes | ❌ No |
| Package delivery | ✅ All carriers | ⚠️ USPS only |
| LLC registration | ⚠️ Varies by state | ❌ Usually not |
| Bank account | ⚠️ Varies by bank | ❌ Often rejected |
| IRS accepted | ✅ With Form 1583 | ✅ Yes |
Why Banks Care About Your Address Type
As part of Know Your Customer (KYC) regulations, banks verify the addresses provided by account applicants. Many banks use automated systems that check whether an address is a CMRA, and some will request additional documentation or deny the application entirely.
However, the CMRA flag alone doesn't tell the full story. A CMRA address classified as residential by the USPS tends to have significantly higher acceptance rates than a CMRA classified as commercial. This is because residential-classified addresses appear more like a traditional home address in the bank's verification systems.
Heads up:If a bank rejects your application, it won't tell you it was the address. You'll see a generic “unable to verify” notice, so it's worth checking before you apply.
What Happened to the USPS Address Lookup?
The USPS Web Tools API, which allowed anyone to verify addresses for free, was retired on January 25, 2026. The replacement API has strict rate limits (60 lookups per hour) and is limited to shipping label use cases. This tool uses USPS-certified data sources to provide the same address intelligence that was previously available through the USPS API.
Good news: this tool is free and has no rate limits for individual use. We pull from the same certified datasets, so you just skip the paperwork.
Frequently Asked Questions
Is a UPS Store address a CMRA?
Yes. All UPS Store locations are registered CMRAs. They are typically classified as commercial addresses, which may face additional scrutiny from banks.
Can I use a CMRA address for my LLC?
It depends on the type of address and your state. Most states allow CMRAs as mailing addresses. Some states also accept them as principal addresses, while others require a physical address. Registered Agent addresses almost always require a non-CMRA physical location.
How accurate is this tool?
This tool uses the same USPS-certified data sources used by banks and financial institutions for address verification. The CMRA status, RDI classification, and deliverability data are sourced from official USPS databases.
Will my address be stored?
No. Address data is processed in real time and is not stored or cached. We do not build an address database from user queries.
What does RDI mean?
RDI stands for Residential Delivery Indicator. It tells you whether the USPS classifies a given address as residential or commercial. This classification affects bank acceptance rates, shipping costs, and how institutions view the address.
