Your routing number is a nine-digit code that identifies which bank or credit union holds your checking account
The routing number (also called a routing transit number or ABA number) tells the financial system which institution to send money to when someone pays you or when you set up automatic transfers. It is not the same as your account number — the routing number is the bank's identifier, while your account number identifies your specific account within that bank.
You need this number when you set up direct deposit for paychecks, arrange bill payments, receive wire transfers, or give someone your banking details for a one-time payment. The routing number is public information — it appears on checks, on your bank's website, and in public databases — so sharing it is safe.
Key Takeaways
- Your routing number is printed on the bottom left of every check you receive from your bank, before your account number.
- You can find your routing number on your bank's website, usually in the customer service or account information section.
- Different branches of the same bank may have different routing numbers, so confirm you have the correct one for your specific location.
- The routing number is nine digits and is always the same for your bank; your account number is different and identifies only your account.
Finding the routing number on a paper check
If you have a checkbook, the routing number is printed at the bottom left of every check. It is the first set of nine digits, followed by your account number (which is longer), then the check number on the far right.
The routing number appears in a special magnetic ink character recognition (MICR) format so that check-sorting machines can read it automatically. You can read it by eye — it is just nine digits in a row, with no dashes or spaces between them.
Finding the routing number on your bank's website
Log into your online banking account and look for a section labeled "Account Information," "Account Details," or "Routing and Account Numbers." Most banks display both numbers together in one place for convenience.
If you cannot find it in your account dashboard, go to your bank's main website and search for "routing number" or look in the customer service or help section. Many banks also list routing numbers by branch location, so you may need to select your branch to see the correct number.
Calling your bank to confirm the routing number
If you are unsure whether you have the right routing number, call the customer service number on the back of your debit card or on your bank statement. A representative can confirm the routing number for your specific branch in less than a minute.
This is especially important if you are setting up a large transfer or direct deposit, because using the wrong routing number will send the money to the wrong bank and delay the transaction by several days while it gets sorted out.
Why different branches may have different routing numbers
Large banks with many branches sometimes assign different routing numbers to different locations. This is less common than it used to be, but it still happens — particularly with banks that grew through mergers or that operate across multiple states.
If you opened your account at one branch and later moved or changed branches, confirm that you have the routing number for the branch where your account is actually held, not the branch where you opened it. Your bank statement will show which branch holds your account.
The difference between routing number and account number
Your routing number identifies your bank. Your account number identifies your specific account within that bank. Together, they form your complete banking address.
When you give someone your banking information for a transfer, you need both numbers. The routing number tells the system which bank to contact; the account number tells that bank which account to deposit the money into. If you give only one, the transaction will fail.
Using the routing number for direct deposit and bill pay
When you set up direct deposit for your paycheck, your employer will ask for your routing number and account number. The routing number ensures your pay goes to the correct bank; the account number ensures it lands in your account, not someone else's at the same bank.
The same applies to bill pay and automatic transfers. If you set up a monthly automatic payment to a creditor or transfer money between your own accounts at different banks, you will need the routing number of the receiving bank.
Frequently Asked Questions
Is it safe to share my routing number?
Yes. Your routing number is public information — it appears on every check you write and is listed on your bank's website. Sharing it does not put your account at risk because someone also needs your account number to access your money. Think of it like sharing your street address without your house key.
What if I use the wrong routing number?
The transfer will be rejected or sent to the wrong bank. The sending bank will catch the error and either return the money to the sender or hold it while they contact you. The process usually takes three to five business days, but your money will not be lost.
Do I need a different routing number for each type of transaction?
No. The same routing number works for direct deposit, wire transfers, bill pay, and any other transaction. You only need one routing number per bank account.
Can I find someone else's routing number?
Yes, routing numbers are public. If you know someone's bank and branch, you can often find their routing number on the bank's website or in a routing number database. However, you would still need their account number to send them money.
What if my bank merged with another bank?
Your routing number may change after a merger. Your bank will notify you and update your account information. Check your most recent statement or log into online banking to confirm your current routing number, especially if you have automatic payments set up.
