Your routing number is a nine-digit code that tells the banking system which bank to send money to
When someone sends you money by wire transfer, ACH (automatic clearing house) payment, or check, they need to know where to send it. Your routing number is the address. It identifies your specific bank or credit union to every other financial institution in the country. Without it, the payment system cannot route the transfer to the right place.
The routing number is not secret and not unique to you — everyone at your bank shares the same one. It is different from your account number, which is unique to your account alone. Together, routing number plus account number tells the system exactly where your money should land.
Key Takeaways
- Your routing number is a nine-digit code specific to your bank or credit union, not to your individual account.
- You can find it on the bottom left of your checks, in your online banking portal, or by calling your bank's customer service line.
- Different branches of the same bank usually share one routing number, but some large banks have multiple routing numbers by region or service type.
- You need your routing number for wire transfers, ACH payments, and setting up direct deposit or automatic bill pay.
Where to find your routing number on a check
If you have checks from your account, the routing number is printed on the bottom left corner. It is the first set of nine digits, before your account number. The format looks like this: the routing number comes first, then your account number, then the check number on the right.
This is the fastest way to find it if you have a checkbook in front of you. The number will be the same on every check from that account.
Finding it online or by phone
Log into your bank's website or mobile app and look for account details or account information. Most banks display the routing number alongside your account number in a section labeled "Account Details," "Account Information," or "Routing and Account Numbers." Some banks require you to click into a specific account to see it.
If you cannot find it online, call your bank's customer service number on the back of your debit card or on your bank statement. Have your account number ready. A representative can give you the routing number in under a minute.
When you have multiple accounts or your bank has multiple routing numbers
If you have a savings account and a checking account at the same bank, they share the same routing number. The routing number identifies the bank, not the account type.
Large banks sometimes have more than one routing number. This usually happens when a bank operates across multiple regions, acquired another bank and kept its routing infrastructure, or offers different services (like business banking) through different processing centers. If you are setting up a transfer and your bank tells you there are multiple routing numbers available, ask which one applies to your account type and location. Your bank's website usually lists all of them, or customer service can tell you which one to use.
What to do if you need the routing number for a specific transaction
When you are setting up a wire transfer, direct deposit, or automatic payment, the form will ask for a routing number. Enter the nine-digit code exactly as it appears — no dashes, no spaces. If you enter it wrong, the money may go to the wrong bank or the transaction may be rejected.
If you are unsure whether you have the right routing number, ask the person or organization requesting it to confirm it matches their records. Some employers and billers have their own lists of routing numbers for common banks and can verify it before processing the payment.
Routing numbers for credit unions and smaller banks
Credit unions and smaller regional banks also have routing numbers. You can find yours the same way — check, online banking, or a phone call to customer service. The process is identical.
If you are moving money between institutions and one of them is a credit union, make sure you have the correct routing number for that credit union. Credit unions do not always appear in every bank's internal directory, so having the right number prevents delays.
Frequently Asked Questions
Is my routing number the same as my bank's main routing number?
Usually yes, but not always. Large banks sometimes have multiple routing numbers by region or service type. The routing number on your checks or in your online banking is the correct one for your account. When in doubt, use the number your bank shows you in your account details rather than a number you find elsewhere.
Can I give my routing number to anyone?
Yes. Your routing number is not sensitive information — it is printed on every check you write and is public. Someone cannot access your account with just the routing number; they also need your account number, and even then, most transactions require additional verification. Share it freely when you need to receive payments.
What happens if I give the wrong routing number?
The payment may be rejected, or it may go to a different bank. If it is rejected, the sender will be notified and can resend it with the correct number. If it goes to the wrong bank, that bank will usually reject it and send it back, which takes a few extra days. Always double-check the routing number before confirming a large transfer.
Do I need a different routing number for wire transfers versus ACH payments?
No. The same routing number works for wire transfers, ACH payments, direct deposit, and automatic bill pay. Some banks print different routing numbers on their websites for different transaction types, but this is rare. Your account's routing number handles all of them.
What if my bank merged with another bank?
Your routing number may stay the same, or it may change. Your bank will notify you if it changes and will usually accept both the old and new routing numbers for a transition period. Check your most recent statement or log into online banking to confirm which routing number is current for your account.
