Short answer
No law we found requires an address on a business check. Under Article 3 of the Uniform Commercial Code, a check is a signed, written order to pay a fixed amount of money, drawn on a bank and payable on demand. An address is not part of that definition. Your bank may still print one by default. Mercury, for example, prints “the legal address we have on file for your business.”
Key takeaways
- The Uniform Commercial Code (UCC) defines a check as a draft “payable on demand and drawn on a bank.” The definition has no address in it.
- Regulation CC, the Federal Reserve rule on check collection, also defines a check without any address element.
- Banks decide what they print by default. Mercury prints the check number, account and routing numbers, the legal business name, and the legal address on file.
- Mercury says its checkbooks cannot be printed with a DBA name or a custom address. A third-party check vendor is the other option.
- Relay says some check vendors will not ship to a PO box and may require shipping to the business address printed on the checks.
- Your bank account still needs an address. Federal rules require banks to collect a physical location for a business customer before opening the account.
Does the law require an address on a business check?
No law we found requires an address on a check. The main rules for checks in the US come from Article 3 of the Uniform Commercial Code (UCC). The Legal Information Institute at Cornell Law School says the UCC is “adopted in some form by every state and the District of Columbia.”
Section 3-104 of the UCC says a “negotiable instrument” is “an unconditional promise or order to pay a fixed amount of money.” The same section says “Check” means “a draft, other than a documentary draft, payable on demand and drawn on a bank.” Section 3-103 says an “Order” means “a written instruction to pay money signed by the person giving the instruction.”
Put together, a check needs a signed instruction, a fixed amount, and a bank to pay it. None of those parts is an address. So a business check with no address printed on it can still be a valid check.
Federal rules point the same way. Regulation CC is the Federal Reserve rule on availability of funds and collection of checks. Its definition of “Check” starts with “A negotiable demand draft drawn on or payable through or at an office of a bank.” That definition names no address either. Banks route a check by its routing number, not by an address. Regulation CC describes it as “The number printed on the face of a check.”
Did this answer your question?
What banks print on a business check
The law does not require an address, but your bank or check vendor decides what gets printed. Two bank help pages show how this works in practice.
Mercury prints its own checkbooks. Its help page lists what “gets printed on each check.” The list ends with “Your legal business name” and “The legal address we have on file for your business.”
Relay does not print checkbooks. Its help page says “You order them from a third-party vendor of your choice.” It says most vendors will ask for “Your business name exactly as it appears on Relay” and “Your business mailing address.”
| Item | Mercury checkbooks | Relay third-party checkbooks |
|---|---|---|
| Check number | Printed on each check | You give the vendor a starting number |
| Account and routing numbers | Printed on each check | You give the vendor both numbers |
| Business name | Your legal business name | Your business name exactly as it appears on Relay |
| Address | The legal address Mercury has on file | Your business mailing address |
| Bank name | Not listed on the help page | Thread Bank, which provides Relay’s banking services |

Which address goes on your business checks
Start with the address your bank has on file. At Mercury, you cannot pick a different address for its checkbooks. Its help page says “At this time, Mercury checkbooks cannot be printed with your DBA company name or a custom address.” The page says you can order checks from a third-party provider instead.
If you use a third-party vendor, Mercury recommends “using the legal business name on your Mercury account when ordering checks through a third-party provider to avoid potential payment issues.” The help page does not give the same advice about the address.
The printed address and the address on file can be two different things. For personal accounts, Chase’s check order page says “You can change the address that appears on your checks during the ordering process.” The same sentence says that to change your mailing address in its system, you go to chase.com/Update. The page does not say whether business check orders work the same way.
When you move, change the address on file and order new checks. Wells Fargo’s small business FAQ says “To make a change of address and order new checks you may log into a secured Wells Fargo Business Online session and submit a request.”
Home address, PO box, or business address on your checks
Whatever you print on a check, every person you pay can read it. If you print your home address, each vendor, landlord, or contractor who gets your check sees where you live. Our guide on using your home address for your LLC covers the other places a home address can become public.
A PO box can cause a problem when you order. Relay’s help page says “Some vendors will not ship to a PO box and may require the checkbook to be shipped to the same business address printed on the checks.” So if your vendor has that rule, a PO box on the checks can block delivery of the checks themselves.
Some boxes do not look like PO boxes. A PO Box with Street Addressing can look like a suite number. Our guide on how to tell if an address is a PO box explains the USPS formats.
What if your LLC does not have a physical address?
The checks may not need an address, but the bank account behind them does. Federal customer identification rules apply to banks. Under 31 CFR 1020.220, “the bank must obtain, at a minimum, the following information from the customer prior to opening an account.”
For a business customer, the required address is narrower than a mailing address. The rule says it “shall be” the following for “a person other than an individual (such as a corporation, partnership, or trust)”: “a principal place of business, local office, or other physical location.”
So an LLC needs a physical location to open the account, even if its checks show a different address or none. Each bank sets its own forms and review. Our guide to business bank account address requirements explains the legal, physical, and mailing address fields banks ask for.
Checklist before you order business checks
Use these steps before you place a check order. They follow the bank pages cited above.
- 1Check the address your bank has on file. At Mercury, that address is the one printed on its checkbooks.
- 2Decide which address you want every payee to see. Avoid your home address if you want to keep it private.
- 3If your bank cannot print the address you want, ask whether a third-party check vendor is allowed for your account.
- 4Use your legal business name exactly as it appears on the bank account.
- 5Ask the vendor whether it ships to a PO box, and where it will send the checkbook.
- 6When you move, change the address on file with the bank and order new checks.
If you are choosing a business address to print on your checks, our pages on a Silicon Valley business address and a Los Angeles business address describe the business addresses save office offers.

States adopt the UCC with their own changes, and bank policies change. Ask your bank about its check rules, and ask a lawyer about a specific check dispute.
