Look up the routing number on the Federal Reserve's official database
The Federal Reserve maintains a public routing number directory that tells you which bank or credit union issued any routing number. Go to frbservices.org, click "Fedwire Directory," and search by routing number. The result shows the institution's legal name, the city where it operates, and whether it's a bank, credit union, or other financial entity.
This is the most reliable source because the Federal Reserve assigns and tracks every routing number in the United States. If a routing number exists and is active, it will appear here. If it doesn't appear, the number is either inactive, fake, or not yet registered.
The search takes seconds and costs nothing. You don't need to log into anything or provide personal information.
Use the ABA's routing number search tool as an alternative
The American Bankers Association (ABA) runs a separate routing number lookup at aba.com. Search by routing number, bank name, or city. The results show the bank's name, address, and phone number.
This tool is useful if you want contact information for the bank—for example, if you need to call them about a wire transfer or account issue. The ABA database is also authoritative, though the Federal Reserve's Fedwire Directory is the primary source that banks themselves use.
Check your own bank statements or online banking portal
If the routing number came from a check, bank statement, or wire transfer confirmation, your own bank's website or app will show you which institution sent or received the money. Log into your account, find the transaction, and look for the receiving or sending bank's name.
This method works best when you already have a relationship with a bank and want to confirm details about a transfer you made or received. It doesn't help if you're looking up a routing number you found elsewhere or received from someone else.
Key Takeaways
- The Federal Reserve's Fedwire Directory at frbservices.org is the official source for routing number ownership and is free to search.
- The ABA's routing number lookup provides the same information plus contact details for the bank.
- A routing number that doesn't appear in either database is either inactive, not yet registered, or incorrect.
- If you received the routing number from a wire transfer or check, your own bank can tell you which institution it belongs to.
- Routing numbers are public information and searching them carries no risk to your account or privacy.
Why routing numbers matter and what they tell you
A routing number identifies a specific bank branch or processing center, not an individual account. It's used to direct wire transfers, ACH payments, and direct deposits to the right place. Every bank has at least one routing number; large banks may have dozens, one for each region or processing facility.
Knowing which bank owns a routing number helps you confirm that a wire transfer went to the right place, verify that a direct deposit is coming from a legitimate employer, or check whether a check you received is from a real bank. It also helps you spot fraud—if someone gives you a routing number that doesn't match the bank they claim to represent, that's a red flag.
What to do if the routing number doesn't appear in any database
If you search a routing number and it doesn't show up in the Federal Reserve's Fedwire Directory or the ABA database, the number is either wrong, inactive, or not yet registered. Don't use it for a wire transfer or direct deposit until you confirm it with the bank directly.
Call the bank's customer service line (use the number on their official website, not one provided by the person who gave you the routing number) and ask them to confirm the correct routing number for your transaction. This takes a few minutes and prevents money from being sent to the wrong place.
Routing numbers vs. account numbers: what's the difference
A routing number identifies the bank; an account number identifies your specific account within that bank. Routing numbers are nine digits and are public. Account numbers vary in length and should be kept private.
When you set up a direct deposit or wire transfer, you need both. The routing number tells the sending bank where to send the money; the account number tells that bank which account to deposit it into. If either one is wrong, the transfer fails or goes to the wrong account.
Frequently Asked Questions
Is it safe to share a routing number?
Yes. Routing numbers are public information and appear on checks, bank statements, and official bank websites. Sharing a routing number alone does not put your account at risk. However, never share your account number or routing number together with someone you don't trust, because that combination can be used to set up unauthorized transfers.
Can a routing number change?
Routing numbers rarely change, but they can if a bank merges, closes a branch, or reorganizes its processing centers. If you're setting up a recurring payment, confirm the routing number with the bank every few years to make sure it's still current.
What if I received a check with a routing number that doesn't exist?
Do not deposit it. Contact the person or organization that issued the check and ask for a corrected version. A check with an invalid routing number will bounce, and you may face fees from your own bank for the failed deposit.
Do credit unions have routing numbers?
Yes. Credit unions use routing numbers just like banks do, and they appear in the same Federal Reserve and ABA databases. Search the routing number the same way you would for a bank.
Can I find a bank's routing number if I only know its name?
Yes. Both the Federal Reserve's Fedwire Directory and the ABA's lookup tool let you search by bank name and city. If the bank is large, you may get multiple results—one for each region or processing center. Call the bank to confirm which routing number applies to your specific transaction.
