What you’re learning
By the end, you should be able to:
- Explain what CMRA means and why it matters for business applications
- Use the USPS ZIP Code Lookup (By Address) tool to check an address (USPS Tools)
- Make a clear decision: CMRA = Y (don’t use) vs CMRA = N (safe to use)
Key terms (know these cold)
CMRA (Commercial Mail Receiving Agency)A private business that receives mail for customers who rent mailboxes (often “private mailboxes”). Examples commonly include mailbox stores and mail-receiving services. (USPS FAQs) Virtual office / mailbox address (common risk)Some “business address” services are actually mail receiving locations. Lenders and verification systems may flag these.
Why lenders careMany lenders want a real physical business location (or at least a non-mailbox address). If the address is flagged as a CMRA, it can trigger an automatic decline or extra verification.
The main idea (1 sentence)
Before you use any business address on LLC paperwork or credit applications, verify whether USPS flags it as CMRA.
Step-by-step: USPS CMRA check (the “do this every time” process)
- Open the USPS ZIP Code Lookup tool. (USPS Tools)
- Choose “Find by Address.” (USPS Tools)
- Enter the full business address (street, city, state; include suite/unit if you have one). (USPS Tools)
- Click Find. (USPS Tools)
- In the results/details, look for:“Commercial Mail Receiving Agency (CMRA): Y or N” (some address tools/databases surface this CMRA designation). (VirtualPostMail)
How to interpret results (decision rules)
If CMRA: Y
✅ You learned something important: this address is flagged as a mail-receiving location.Action: Do not use this address for forming your business or applying for credit.
If CMRA: N
This address is not flagged as a CMRA in the database check.Action: Generally safe to use on business applications.
Quick reminder: USPS tools note that ZIP results don’t confirm a specific company is located there—so this is an address-quality check, not a “business verification” tool. (PostalPro) Pro tips (stuff that saves people from getting denied)
- Check every location manually. Even popular providers can have some locations that flag CMRA and others that don’t. (VirtualPostMail)
- Don’t assume “Suite” = real office. Some executive suites and mail centers look identical in formatting.
- Keep your addresses consistent across systems (state filing, IRS, D&B, banks, vendors). Mismatches can trigger reviews.
If you already used a CMRA address (fix plan)
Fix the official records first, then update everywhere else.
- IRS: Use Form 8822-B to update the business mailing address/location with the IRS. (IRS)
- State (Secretary of State): Update your LLC address (state process varies).
- Then update D&B, banks, business credit bureaus, and key vendors so everything matches.
