Your routing number is printed on the bottom left of every check you receive from your bank

The routing number is a nine-digit code that identifies which bank or credit union holds your account. It appears in the bottom left corner of your checks, before your account number. If you have checks in front of you right now, open the box and look at the first line of numbers at the bottom of any check — that's your routing number.

You need this number when you set up direct deposit, arrange wire transfers, or authorize automatic payments. It tells the sending bank exactly where to send money. Without it, the transaction either fails or goes to the wrong place.

If you don't have checks or can't find them, there are other ways to locate this number that take less than a minute.

Key Takeaways

  • Your routing number is the first nine-digit code printed at the bottom left of any check you own.
  • Your bank's website and mobile app both display your routing number in the account details section, usually under "Account Information" or "Routing and Account Numbers".
  • You can call your bank's customer service line and confirm your routing number in under two minutes.
  • The routing number stays the same for all accounts at the same bank branch, but different branches of the same bank may have different routing numbers.

Finding your routing number online or in your bank's app

Log into your bank's website or open the mobile app on your phone. Look for a section labeled "Account Information," "Account Details," or "Routing and Account Numbers" — the exact name varies by bank. Most banks put this in the main dashboard or under a menu that says "Accounts" or "Settings."

Once you find that section, you'll see both your routing number and account number displayed together. The routing number is always nine digits. Write it down or take a screenshot if you need it for a form or setup process.

If you can't find it in the app, try the bank's website on a computer — sometimes the layout is clearer there. You can also search the bank's help section for "routing number" and it will point you to the exact page.

Calling your bank to confirm your routing number

Pick up the phone and call the customer service number on the back of your debit card or on your bank statement. Tell the representative you need your routing number. They'll ask you to verify your identity — usually your account number and the last four digits of your Social Security number — and then read it to you.

This takes about two minutes and is the fastest way if you're on the phone anyway for another reason. Write down the number they give you, because you'll need it right away for whatever transaction prompted the call.

Understanding the nine digits on your check

The bottom of a check has three separate groups of numbers. On the far left is the routing number (nine digits). In the middle is your account number (usually 10 to 12 digits). On the right is the check number.

The routing number never changes as long as you keep an account at the same bank branch. If you move to a different branch or switch banks, you get a new routing number. Your account number, by contrast, stays with you as long as the account exists — even if you close it and reopen it later at the same bank, you may get a new account number.

What happens if you use the wrong routing number

If you give someone the wrong routing number, the money usually bounces back to the sender within one to three business days. The sending bank tries to deliver it, can't match it to an account, and returns it. You'll see the funds reappear in the sender's account, and they'll have to try again with the correct number.

In rare cases, a wrong routing number might route money to a different bank entirely, which takes longer to reverse — sometimes up to a week. This is why it's worth taking 30 seconds to double-check the number before you submit a form or authorize a transfer.

Routing numbers for different types of accounts

Your checking account, savings account, and money market account at the same bank all use the same routing number. The routing number identifies the bank, not the account type. Your account number is what distinguishes one account from another.

If you have accounts at multiple banks, each bank has its own routing number. Some large banks also have different routing numbers for different regions or branches, so if you've moved or switched branches, confirm you have the current one for your location.

Frequently Asked Questions

Can I find my routing number on my debit card?

No. Your debit card shows your card number and expiration date, but not your routing number. You'll find it on a check, in your bank's app, or by calling customer service.

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

Not always. Large banks have multiple routing numbers for different branches or regions. The routing number on your check is the correct one for your specific account. If you're setting up direct deposit and the bank's website gives you a different number, use the one from your check or your account details page.

What if my bank merged with another bank?

Your routing number may change after a merger. Check your most recent statement or log into your account online to see the current routing number. If you have old checks, don't use them for direct deposit — the routing number may no longer be valid.

Do I need my routing number to transfer money between my own accounts?

Not usually. If both accounts are at the same bank, you can transfer between them using just the account numbers. You only need the routing number when sending money to a different bank or setting up direct deposit from an employer.
