Your bank account number is printed on the bottom left of your checks, in your online banking portal, or on statements your bank mails you

The fastest way is to look at a check from your checkbook. The account number appears as the second set of digits on the bottom of the check, between the routing number on the left and the check number on the right. If you do not have checks, log into your bank's website or mobile app — your account number is almost always visible on the dashboard or in an "Account Details" section. If you prefer to call, your bank's customer service line can read it to you over the phone after you verify your identity.

Paper statements also show your account number, usually near the top. If your bank sends statements by mail, look at the most recent one. If you have switched to paperless statements, you can read past statements from your online banking portal and find the number there.

Key Takeaways

  • Your account number appears on the bottom of any check you write, as the middle set of digits between the routing number and check number.
  • Log into your bank's website or app to find your account number on the account dashboard or in account details.
  • Call your bank's customer service line and they will provide your account number after you answer security questions.
  • Paper or digital statements from your bank display your account number near the top of the document.

Finding it online without logging in

If you have forgotten your login credentials, you do not need to retrieve your account number from your online portal. Call your bank's main customer service number — it is on the back of your debit card, on your statements, or on the bank's website. Have your Social Security number, date of birth, and the phone number or address on file ready. The representative will verify your identity and read your account number to you.

Some banks also allow you to look up your account number through their mobile app even if you are not logged in, though this varies by bank. Check the app's login screen for an option like "Forgot password?" or "Account lookup" — a few institutions offer a way to retrieve account information without a full login.

What to do if you cannot find it

If you have no checks, cannot access your online account, and do not have statements, visiting a branch in person is the most direct route. Bring a photo ID and ask a teller for your account number. They will verify who you are and provide it when ready. This takes about five minutes.

If you are locked out of your online account because you cannot remember your password, use the "Forgot password" or "Reset password" link on your bank's login page. You will usually be asked to verify your identity through email or a security question, and then you can create a new password and log in to see your account number.

Account number versus routing number

The account number and routing number are two different things, and you may need both for direct deposit, wire transfers, or setting up automatic payments. Your routing number identifies which bank or branch you use — it is the same for all customers at that bank location. Your account number is unique to you and identifies your specific account within that bank.

On a check, the routing number is the first set of digits on the bottom left, the account number is the second set in the middle, and the check number is on the right. When you set up direct deposit at work or arrange a wire transfer, you will usually need to provide both numbers together.

Keeping your account number safe

Your account number is not as sensitive as your PIN or password, but it should still be treated as private information. Do not share it with anyone who calls you unsolicited or in response to an email you did not initiate. Legitimate businesses and government agencies will not ask for your account number by phone or email unless you contacted them first.

If you write checks, your account number is visible to anyone who handles the check — the payee, their bank, and anyone else in the payment chain. This is normal and unavoidable. If you are concerned about a specific transaction, contact your bank directly rather than responding to a message claiming to be from your bank.

Frequently Asked Questions

Can I find my account number if I have never set up online banking?

Yes. Call your bank's customer service number, which is on the back of your debit card or on statements. Have your ID and personal information ready. A representative will verify you and provide your account number over the phone.

Is my account number the same as my debit card number?

No. Your debit card number is printed on the front of the card and is different from your account number. Your account number appears on checks and in your online banking portal. They are separate identifiers.

What if I lost my checks and do not have online access?

Visit a branch in person with a photo ID and ask a teller for your account number. They will verify your identity and provide it. This is the fastest in-person option if you cannot use phone or online methods.

Do I need my account number to use my debit card?

No. You use your debit card number, expiration date, and CVV for purchases. Your account number is needed for direct deposit, wire transfers, and automatic bill payments — not for everyday card use.
