How to look up a routing number and find the bank
You can find which bank owns a routing number using the Federal Reserve's official routing number search tool, a bank's own website, or a third-party routing number database. The fastest method depends on what information you already have — if you know the bank name, searching their site takes seconds; if you only have a routing number, the Federal Reserve lookup is the most reliable source.
The Federal Reserve's routing number search is the authoritative tool. Go to frbservices.org, select "Routing Number Lookup," enter the nine-digit routing number, and the system returns the bank name, address, and phone number. This works for any active routing number in the United States, whether the bank is large or regional.
If you have the bank name instead, visit the bank's official website and look for a "routing number" or "wire transfer information" page — most banks list this in their help section or under account details. You can also call the bank's customer service line and ask directly.
Key Takeaways
- The Federal Reserve's routing number lookup at frbservices.org is the official source and works for any U.S. bank routing number.
- If you know the bank name, their website or customer service line will give you the routing number faster than a search tool.
- A routing number identifies the specific branch or processing center, so the same bank may have multiple routing numbers for different locations or services.
- Third-party banking websites like Wise and Bankrate maintain routing number databases, but the Federal Reserve tool is more authoritative for verification.
Using the Federal Reserve's official lookup
The Federal Reserve maintains the authoritative registry of all active routing numbers. To search it, go to frbservices.org, click on "Routing Number Lookup" in the main menu, and enter the nine-digit routing number in the search box. Within seconds, the system displays the bank or credit union name, the city and state where that routing number is registered, and a phone number for that institution.
This tool is free and requires no login. It covers all banks, credit unions, and financial institutions that process payments through the Federal Reserve system. If a routing number does not appear in this search, it is either inactive, incorrectly entered, or not registered with the Federal Reserve — which is rare for legitimate U.S. banks.
Write down or screenshot the result, especially if you need to verify the information later or share it with someone else. The Federal Reserve's data is updated regularly, so a routing number that was valid last year should still appear here unless the bank closed or merged.
Finding a routing number when you know the bank
If you already know which bank you use, their website is usually the fastest place to find the routing number. Log into your online banking account and look for a section labeled "Account Information," "Wire Transfer Details," or "Routing Number." Most banks display this information on the account summary page or in a downloadable document.
If you cannot find it online, call the bank's customer service number on the back of your debit card or on their website. Tell them you need the routing number for your account or for a specific branch. They will give you the correct number immediately and can clarify whether you need the main routing number or a branch-specific one.
For checks, the routing number is printed at the bottom left of the check itself, in the first set of nine digits. This is the fastest way to find it if you have a check from that account on hand.
Why banks have multiple routing numbers
A single bank often has more than one routing number because routing numbers are tied to specific branches, processing centers, or services rather than to the bank as a whole. A large national bank might have one routing number for its New York processing center, another for its California center, and a third for wire transfers or ACH payments.
This matters when you are setting up a direct deposit or wire transfer, because using the wrong routing number can send your money to the wrong processing center and delay the transfer by a day or more. Always confirm you have the routing number for the specific branch or service you are using, not just any routing number the bank owns.
If you are unsure which routing number to use, ask the bank directly or check the documentation for the transaction you are setting up — most forms specify which routing number applies.
Third-party routing number databases
Websites like Wise, Bankrate, and ABA (American Bankers Association) maintain searchable databases of routing numbers. These are useful for quick lookups and often include additional details like the bank's address and phone number. However, they are not official sources — they pull data from the Federal Reserve and update it periodically, so there can be a lag if a routing number changes.
Use third-party databases as a starting point, but verify the result using the Federal Reserve's official tool if the routing number is for a critical transaction like a wire transfer or a large direct deposit. The Federal Reserve's data is always current, while third-party sites may show outdated information.
These databases are free and do not require registration. Some also offer reverse lookups, where you enter a bank name and they return all known routing numbers for that institution — useful if you need to find the routing number for a specific branch.
What to do if the routing number does not appear in any search
If a routing number does not show up in the Federal Reserve lookup or any other database, the number may be incorrect, inactive, or not registered with the Federal Reserve. Start by double-checking that you entered all nine digits correctly — a single wrong digit will return no results.
If the number is correct but still does not appear, contact the bank directly using the phone number or address on any documents you have from them. They can confirm whether the routing number is still active or tell you what the current routing number is. Banks sometimes change or retire routing numbers when they merge, relocate, or restructure their processing centers.
If someone gave you this routing number for a transaction, ask them to verify it with their bank before you use it. Using an invalid routing number can cause a payment to fail or be returned, which delays the transaction and may trigger fees.
Frequently Asked Questions
Is the routing number the same for all branches of the same bank?
Not always. Large banks often have different routing numbers for different regions or services. A Bank of America branch in Texas might use a different routing number than one in New York. Always use the routing number for the specific branch or service you are using, not just any routing number the bank owns.
Can I use any routing number from the same bank?
It depends on the transaction. For some payments, any routing number from the bank will work because they route to the same processing center. For others, like direct deposits or wire transfers, using the wrong routing number can send your money to a different branch or delay the transfer. When in doubt, use the routing number for your specific branch or account.
What if I find two different routing numbers for the same bank?
The bank likely has multiple routing numbers for different purposes — one for ACH transfers, one for wire transfers, one for a specific region, and so on. Check the document or form you are filling out to see which routing number it asks for. If it does not specify, contact the bank and tell them what type of transaction you are doing.
How do I know if a routing number is fake or fraudulent?
Search it in the Federal Reserve's routing number lookup tool. If it appears with a real bank name and address, it is legitimate. If it does not appear, the number is either incorrect or not registered with the Federal Reserve. Never send money to a routing number you cannot verify through the Federal Reserve or the bank's official website.
Can I look up a routing number without knowing the bank name?
Yes. If you have the nine-digit routing number, enter it into the Federal Reserve's lookup tool and it will return the bank name and location. This works even if you have never heard of the bank before. The Federal Reserve's database covers all active routing numbers in the U.S. banking system.
