Your routing number is printed on the bottom left of your checks, or you can find it on your bank's website or by calling customer service

The routing number is a nine-digit code that identifies which bank or credit union holds your account. It tells the payment system where to send money. You need it to set up direct deposit, pay bills electronically, or receive wire transfers. The fastest way to find it is to look at a check you have on hand — it is the first set of numbers on the bottom left, before your account number.

If you do not have checks or cannot read them clearly, your bank's website has it listed in the account details section, usually under "Routing Information" or "Bank Details". You can also call your bank's customer service line and they will give it to you in under a minute. Some banks print it on statements too, though not all do.

Key Takeaways

  • The routing number is the first nine-digit code on the bottom left of a check, before your account number.
  • Your bank's website displays the routing number in the account information or settings section, accessible after you log in.
  • Calling your bank's customer service number on the back of your debit card will get you the routing number when ready.
  • Different branches of the same bank may have different routing numbers, so confirm you have the correct one for your specific branch.
  • Wire transfers and ACH payments both require the routing number, so you will need it for most electronic money movements.

Finding it on a check

If you have a checkbook, the routing number is always in the same place: the bottom left corner. It is nine digits long and comes before your account number. The account number is longer and sits in the middle. At the far right is the check number. All three are printed in magnetic ink so machines can read them.

The numbers are small but readable. If your checks are old or worn, the ink may be faded — in that case, move to the website or phone method instead. Do not guess at a faded number, because sending money to the wrong routing number means it goes to the wrong bank, and recovery takes days.

Looking it up on your bank's website

Log into your online banking account and navigate to the account details or settings section. Most banks label this "Account Information", "Bank Details", or "Routing Information". The routing number is usually listed alongside your account number and the bank's address.

If you cannot find it in the obvious place, use the search function on the website and type "routing number". Most banks have a dedicated page for this information. Some also list it under "Wire Transfer Instructions" because that is one of the most common reasons people need it. If the website does not show it clearly, the phone method is faster than hunting through menus.

Calling your bank directly

The fastest method if you are in a hurry is to call the customer service number on the back of your debit card or on your bank statement. Tell them you need the routing number for your account. They will ask you to verify your identity — usually your account number and the last four digits of your Social Security number — and then give you the number when ready.

This takes about two minutes total. Have a pen ready to write it down. If you are setting up direct deposit or a wire transfer and the important date is soon, calling is the safest route because you get confirmation that the number is correct for your specific branch and account type.

Why the routing number matters for different transactions

The routing number tells the payment system which bank to send money to. When you set up direct deposit for your paycheck, your employer uses your routing number and account number together to deposit funds into your specific account at your specific bank. Without the routing number, the system does not know which bank to contact.

For ACH transfers — the electronic system that moves money between accounts — both the sending and receiving banks use routing numbers to confirm the transaction is going to the right place. Wire transfers also require it. Even bill pay through your bank's website uses your routing number behind the scenes to route the payment correctly. If the routing number is wrong, the money either bounces back or goes to someone else's account, and sorting it out takes several business days.

Routing numbers vary by branch and bank type

A large bank may have different routing numbers for different regions or branches. Chase, Bank of America, and Wells Fargo each have multiple routing numbers depending on which state your account is held in. Credit unions have their own routing numbers too, separate from any bank's number.

This is why it matters to get the routing number for your specific branch, not just your bank. If you move your account to a different branch or switch to a different bank entirely, the routing number changes. Always confirm you have the current routing number for the account you are actually using, especially if you have accounts at multiple banks or branches.

What to do if you cannot find your routing number

If your bank's website is down, you do not have a debit card, and you do not have checks, you can search online for your bank's routing number using the bank's name and your state. The Federal Reserve maintains a database of routing numbers, and many third-party sites pull from it. Search "[Your Bank Name] routing number [Your State]" and you should find it within seconds.

However, confirm the number matches what your bank lists on its official website or what customer service tells you. Scam sites sometimes appear in search results with incorrect numbers, so always verify through an official channel before using it for a transaction. If you are uncertain, call your bank — that is the safest option.

Frequently Asked Questions

Is the routing number the same for all accounts at my bank?

Not always. Large banks have different routing numbers by state or region. Your specific routing number depends on which branch your account is held at. Check your bank's website or call to confirm you have the routing number for your account's branch, not just any branch of that bank.

Can I use someone else's routing number if they bank at the same place I do?

Only if you both have accounts at the exact same branch. Even then, you should use your own routing number for transactions tied to your account. Using someone else's routing number for your own account can cause the payment to go to the wrong place or be rejected.

What happens if I give the wrong routing number?

The payment either bounces back to the sender or goes to a different bank. If it goes to the wrong bank, recovery takes several business days and requires the sending bank to file a trace. Always double-check the routing number before submitting a wire transfer or setting up direct deposit.

Do I need a routing number to use my debit card?

No. You only need a routing number for electronic transfers between accounts — direct deposit, ACH payments, wire transfers, and bill pay. Swiping or inserting your debit card at a store does not require it.

Is my routing number the same as my bank's main number?

No. Your bank's customer service phone number is different from the routing number. The routing number is a nine-digit code used only for electronic transfers. The phone number is what you call to speak to a person.
