Look up a routing number using the Federal Reserve's official database
The Federal Reserve maintains a public routing number database that you can search for free. Go to frbservices.org, click "Routing Number Lookup," and enter the nine-digit routing number. The database will return the bank name, the city where that routing hub is located, and the Federal Reserve district that serves it.
This is the most reliable source because the Federal Reserve assigns and tracks every routing number used in the U.S. banking system. If a routing number exists and is active, it will show up here. If it does not appear in this database, the number is either invalid, inactive, or was entered incorrectly.
The search takes seconds and requires nothing but the routing number itself. You do not need to log into anything or provide personal information.
Key Takeaways
- The Federal Reserve's routing number lookup at frbservices.org is the official, free way to identify which bank owns any routing number.
- A routing number that does not appear in the Federal Reserve database may be inactive, mistyped, or fraudulent.
- Routing numbers are tied to specific bank branches or processing centers, not to individual accounts, so the lookup will tell you the bank and location but not account details.
- If you received a routing number from a bank or payment, verify it through the Federal Reserve before using it for transfers or deposits.
Why the Federal Reserve database is more reliable than bank websites
Bank websites sometimes list routing numbers for their main office, but they may not list every routing number the bank uses. Large banks operate multiple processing centers, and each one may have its own routing number. The Federal Reserve database includes all of them.
Third-party websites that claim to look up routing numbers often pull from outdated lists or make mistakes. The Federal Reserve updates its database in real time as banks merge, close branches, or change their processing infrastructure. If you are verifying a routing number before sending money, the Federal Reserve source is the one to trust.
What the lookup result tells you and what it does not
When you search a routing number, you will see the bank name and the city where that routing hub processes transactions. You may also see which Federal Reserve district handles that location. This tells you the bank and the general region, but it does not tell you which specific branch the account belongs to or any details about the account holder.
Routing numbers are not secret — they are printed on the bottom left of every check and are public information. Knowing a routing number does not give anyone access to an account. You need both the routing number and the account number to move money, and even then, the receiving bank will verify the account exists before completing the transfer.
How to read a routing number if you have one in front of you
A routing number is always nine digits. On a check, it appears in the bottom left corner, printed in a special magnetic ink that machines can read. The format looks like this: the first four digits identify the Federal Reserve district and the bank, the next four identify the specific branch or processing center, and the last digit is a check digit that validates the whole number.
You do not need to understand this structure to look it up — just enter all nine digits into the Federal Reserve search box exactly as they appear. If you are copying from a check or email, double-check that you have not accidentally included a space or skipped a digit, because even one wrong number will return no result.
What to do if the routing number does not appear in the database
If the Federal Reserve lookup returns no results, the number is either wrong, inactive, or not a real routing number. Start by checking that you entered all nine digits correctly and that there are no spaces or extra characters.
If the number is correct but still does not show up, contact the bank or organization that gave you the number and ask them to confirm it. If someone sent you a routing number via email or text and you cannot verify it through the Federal Reserve, do not use it — it may be part of a scam. Legitimate banks will always provide routing numbers that appear in the Federal Reserve database.
Routing numbers versus account numbers: why they are not the same
A routing number identifies the bank or processing center. An account number identifies your specific account at that bank. You need both to send or receive money, but they serve different purposes. The routing number tells the banking system which bank to contact; the account number tells that bank which account to move the money into or out of.
This is why you can safely share your routing number — it is printed on every check and is public. Your account number should stay private, because that is what someone would need along with the routing number to access your account. If you are unsure whether a number you have is a routing number or an account number, the Federal Reserve lookup will tell you: if it returns a bank name, it is a routing number; if it returns nothing, it is probably an account number or an invalid number.
Frequently Asked Questions
Can I look up a routing number by bank name instead of by number?
The Federal Reserve database searches by routing number, not by bank name. If you know the bank but not the routing number, visit the bank's official website or call their customer service line. They will provide the correct routing number for your account or branch.
Do different branches of the same bank have different routing numbers?
Sometimes. Large banks may use one routing number for all branches, or they may assign different routing numbers to different processing centers or regions. The Federal Reserve database will show you all the routing numbers a bank uses, but you may need to contact the bank to know which one applies to your specific branch or account.
Is it safe to share my routing number?
Yes. Your routing number is public information printed on your checks and listed in the Federal Reserve database. Someone cannot access your account with only the routing number — they would also need your account number and would have to go through the bank's verification process to move money.
What if I think a routing number is fake or part of a scam?
Search it in the Federal Reserve database. If it does not appear, it is not a valid routing number. If someone is pressuring you to send money using an unverifiable routing number, do not do it. Contact your bank or local law enforcement if you suspect fraud.
Can a routing number change?
Routing numbers can change when banks merge, close processing centers, or restructure their operations. If you have an old routing number that no longer works, contact the bank directly for the current one. The Federal Reserve database will show only active routing numbers.
