Your checking account number is printed on the bottom left of your checks, in your online banking portal, or by calling your bank

The easiest place to look is the bottom of a check you have from that account. You will see a series of numbers printed in magnetic ink. The account number is the middle set of numbers — usually 10 to 12 digits long. If you do not have checks handy, log into your bank's website or mobile app, go to your account details or account summary, and the number will be listed there. If you cannot access online banking, call your bank's customer service number (on the back of your debit card or on your bank's website) and give them your name and identification — they will read it to you.

You need this number when you set up direct deposit for paychecks, arrange automatic bill payments, or receive a wire transfer. It is different from your routing number, which directs money to the right bank, and different from your debit card number. Your account number stays the same as long as you keep that account open.

Key Takeaways

  • The account number appears on the bottom left of your checks, between the routing number and a check number.
  • You can find it in your online banking portal under account details or account summary without needing a check.
  • Calling your bank's customer service line and providing your name and ID will get you the number over the phone.
  • Your account number is different from your routing number and your debit card number, though all three may be needed for certain transactions.

Finding it on a paper check

Look at the bottom of any check from your account. You will see three separate groups of numbers printed in a special magnetic ink. Reading from left to right, the first group is your bank's routing number (usually nine digits), the middle group is your account number (usually 10 to 12 digits), and the third group is the check number itself.

The account number is the one you need for most banking tasks. Write it down or take a photo so you have it saved. If you have never ordered checks or your checks are all used up, move to the next method — you do not need a physical check to find this information.

Finding it in online banking

Log into your bank's website or open the mobile app on your phone. Look for a section labeled "Account Details," "Account Information," "Account Summary," or sometimes just "Accounts." Your account number will be displayed there, usually near the account name and balance.

If you cannot find it in those sections, look for a link that says "View Account Number" or "Account Number" — some banks hide it behind an extra click for security. If your bank's app or website is unfamiliar to you, the search or help function (usually a question mark icon) can point you to the right page. This method works even if you have no checks at all.

Finding it by phone

Call the customer service number on the back of your debit card, or find the number on your bank's website. Tell the representative your name and provide a form of identification they ask for — this might be your Social Security number, date of birth, or answers to security questions you set up when you opened the account.

Once they confirm who you are, they will read your account number to you. Write it down as they say it, and ask them to repeat it so you have it correct. This method works even if you have lost access to your online banking or do not have checks.

What your account number is used for

You will need your account number when you set up direct deposit so your employer can deposit your paycheck straight into your account. You also need it to arrange automatic bill payments with companies like utilities or insurance. If someone is sending you money by wire transfer or ACH transfer (a slower, free electronic transfer), they will ask for your account number and routing number.

Some employers or government agencies may also ask for it when you are setting up tax withholding or receiving a tax refund. Keep it private — do not share it in emails or texts, and do not give it to anyone who calls you claiming to be from your bank unless you called them first.

Account number versus other numbers on your account

Your account number is not the same as your routing number. The routing number tells the banking system which bank to send money to; the account number tells it which account at that bank. You need both for wire transfers and direct deposits. Your debit card number is also different — it is the 16-digit number on the front of your card, and it is used for purchases and ATM withdrawals, not for bank transfers.

Your check number (the third group of numbers on the bottom of a check) is different too — it is just a way to track individual checks you write. None of these numbers are interchangeable, so make sure you are using the right one for what you are trying to do.

If you cannot find your account number

If you have no checks, cannot access online banking, and do not have a debit card, visiting your bank in person is the most direct option. Bring a photo ID and ask a teller for your account number. They will look it up in their system and give it to you on the spot.

If you have forgotten your online banking password, most banks have a "Forgot Password" link on their login page that will walk you through resetting it. Once you are back in, your account number will be visible. If you are locked out of your account for security reasons, the bank may require you to visit in person or call with extra verification before they restore access.

Frequently Asked Questions

Is my account number the same at every bank I use?

No. Each account at each bank has its own unique account number. If you have a checking account and a savings account at the same bank, they have different account numbers. If you have an account at a different bank, that account has a completely different number.

Can someone steal money from my account if they know my account number?

They would also need your routing number to set up a transfer, and most banks require additional verification before allowing large transfers. Still, do not share your account number with people you do not trust. If someone asks for it unsolicited, hang up or close the message — your bank will never ask for it this way.

What if my account number is different on my check than in my online banking?

This is very rare, but if you notice a difference, call your bank when ready. It could indicate a printing error on the checks or a problem with your account. Your bank can confirm which number is correct and may need to reorder your checks.

Do I need my account number to use an ATM?

No. You use your debit card and PIN at an ATM. Your account number is only needed for transfers, direct deposits, and bill payments — not for withdrawals or balance checks at the machine.
