Look up the routing number on the Federal Reserve's official database
The Federal Reserve maintains a public routing number directory at fedwire.frb.org. Go to the Fedwire Participant Search page, enter the nine-digit routing number, and the system will return the bank or credit union name, location, and whether it processes wire transfers. This is the most direct source because the Federal Reserve assigns and tracks every routing number in the United States.
The search takes seconds and requires only the routing number itself. You do not need to know the bank name first. If the number is valid and active, the bank's legal name and city will appear. If nothing comes back, the routing number may be inactive, incorrect, or not yet registered in the system.
Use the ABA's routing number lookup tool
The American Bankers Association (ABA) hosts a routing number search at aba.com/routing-number-search. Enter the nine digits and the tool returns the bank name, address, and phone number. The ABA maintains this database because it assigns routing numbers to member banks, though the Federal Reserve's database is the official record.
The ABA tool often includes additional details like the bank's phone number and whether it handles ACH transfers (automatic bill payments and direct deposits). Both the Federal Reserve and ABA databases pull from the same underlying data, so results should match.
Check your bank statement or online banking portal
If the routing number is from your own account, your bank statement lists it clearly, usually at the bottom left corner next to your account number. Your online banking portal also displays it under account details or settings. This confirms the routing number belongs to your bank without needing a separate lookup.
This method works only if you already know which bank issued the account. For a routing number you received from someone else or found on a check, use the Federal Reserve or ABA search instead.
Key Takeaways
- The Federal Reserve's Fedwire Participant Search is the official source for routing number ownership and is free to use.
- The ABA routing number lookup tool provides the same information plus additional details like phone numbers and transfer capabilities.
- A valid routing number search will return the bank's legal name and city within seconds.
- If a routing number returns no results, it may be inactive, incorrect, or not yet registered in the system.
- Your own bank statement or online portal displays your routing number if you need to confirm your bank's number.
What to do if the routing number does not appear in either database
A routing number that produces no results in either the Federal Reserve or ABA database may be outdated, mistyped, or belong to a very small credit union not yet indexed. Check that you have copied all nine digits correctly—routing numbers are always nine digits, and a single wrong digit will return no match.
If you are certain the number is correct, contact the bank or credit union directly using a phone number you find independently (not from the person who gave you the routing number). Ask them to confirm whether that routing number belongs to them. This is especially important if you are about to send money to an account you do not know well.
Why routing numbers matter for wire transfers and direct deposits
A routing number identifies the specific bank branch that holds an account, while the account number identifies the individual account within that bank. Together, they tell the sending bank exactly where to send money. If either number is wrong, the transfer may be delayed, rejected, or sent to the wrong account.
Wires and ACH transfers (direct deposits, bill payments) both require a correct routing number. Checks also print the routing number in magnetic ink at the bottom, which is how check-processing machines sort them. Confirming the routing number before sending money reduces the risk of costly mistakes.
Differences between routing numbers for wires, ACH transfers, and checks
Most banks use the same routing number for all three methods—wires, ACH transfers, and checks. However, some large banks maintain separate routing numbers for different purposes or regions. The Federal Reserve database shows which routing numbers handle wire transfers specifically. If you are sending a wire, confirm the routing number works for wires before sending.
When someone gives you a routing number for a direct deposit or bill payment, it is almost always the standard routing number that works for ACH transfers. If they specify it is for wires only, ask for the ACH routing number instead, because the two are not interchangeable for all transaction types.
Frequently Asked Questions
Can a routing number belong to more than one bank?
No. Each routing number is assigned to one specific bank or credit union branch. However, a single large bank may have multiple routing numbers for different regions or purposes. If you search a routing number and get a result, that number belongs only to that institution.
What if I find the routing number but the bank name looks wrong?
The legal name of a bank may differ from its marketing name. For example, a bank may operate under one brand name but be registered under a different corporate name in the Federal Reserve system. If the routing number is correct, trust the official database result over what you expected the name to be.
Do credit unions have routing numbers?
Yes. Credit unions have routing numbers just like banks. The Federal Reserve and ABA databases include credit unions. A routing number that returns a credit union name is just as valid as one that returns a bank name.
Can I use a routing number to find someone's account?
No. A routing number only identifies the bank, not the account holder or account number. You cannot reverse-search a routing number to find personal information. You need both the routing number and account number to send money to a specific person.
What should I do before sending money using a routing number I just looked up?
Confirm the routing number matches the bank the person told you they use. Call the person back using a phone number you know is correct and ask them to verify the routing number. This prevents sending money to the wrong bank if someone gave you incorrect information intentionally or by mistake.
