Check your checks or debit card first

Your account number appears on the bottom left of every check you write. Look at the string of numbers printed in magnetic ink at the base of the check — the middle set is your account number, usually 10 to 12 digits long. If you have checks on hand, this is the fastest place to look.

Your debit card does not print your account number on its face, but your bank can tell you the account number tied to that card in seconds. Call the number on the back of your card or log into your online banking portal.

Key Takeaways

  • Your account number appears on the bottom of your checks in the middle set of numbers between the routing number and the check number.
  • Your bank's website or mobile app shows your account number in the account details or settings section once you log in.
  • Calling your bank's customer service line — the number on your debit card or statement — takes two minutes and requires your ID to verify.
  • Your monthly bank statement lists your account number at the top or in the account summary section.
  • If you have not received statements or checks yet, your bank can mail or email your account number once they confirm your identity.

Log into your online banking account

Most banks display your account number prominently once you sign in. Look for a section labeled "Account Details," "Account Information," or "My Accounts" — the account number is usually listed there alongside your balance and account type.

If you cannot find it in the main view, check the settings or profile section. Some banks hide it one level deeper to protect against accidental sharing. The mobile app typically shows the same information as the website version.

Call your bank's customer service line

The fastest way if you do not have online access is to call the number printed on the back of your debit card or on your most recent statement. Have your Social Security number or ID ready — the bank will ask you to verify your identity before reading your account number aloud.

Wait times vary by bank and time of day, but most calls are answered within five to ten minutes during business hours. You can also visit a branch in person with your ID and ask a teller to provide it.

Check your monthly bank statement

Paper statements and electronic statements both list your account number. On a paper statement, it usually appears at the top of the page or in a box labeled "Account Information." On an electronic statement (PDF or email), look in the header or the first section after the date.

If you have not received a statement yet, you can request one from your bank. Most banks can email a recent statement within one business day, and that statement will include your account number.

Ask your bank to send it by mail or email

If you have just opened an account and have not yet received checks or statements, contact your bank directly and ask them to send your account number. Provide your full name, date of birth, and the phone number or address on file. Most banks will email it to you the same day or mail it within three to five business days.

Some banks include the account number in the welcome packet they send when you open an account, so check any mail from your bank before calling.

What to do if you cannot reach your bank

If your bank is closed or you cannot reach customer service, your account number is not urgent to find — it only matters when you need to set up direct deposit, wire money, or receive a payment. You can wait until business hours to call or visit a branch.

If you are waiting for a refund or payment and need to provide your account number immediately, contact the organization sending the payment and ask if they can look it up using your name and the bank name instead. Many can, though it takes longer.

Frequently Asked Questions

Is my account number the same as my routing number?

No. Your routing number identifies your bank (nine digits), and your account number identifies your specific account at that bank (usually 10 to 12 digits). Both appear on the bottom of your checks, with the routing number first and the account number in the middle.

Can I find my account number on my online bill pay history?

Yes. If you have paid a bill online through your bank, the confirmation page or email receipt often shows the account number the payment came from. You can also log into your bank's bill pay section and view past payments to see which account was used.

What if I have multiple accounts at the same bank?

Each account has its own number. When you log into online banking, you will see all your accounts listed separately, each with its own account number. Make sure you are looking at the correct account before providing the number to anyone.

Do I need to memorize my account number?

No. You only need to know where to find it when you need it. Write it down and keep it in a safe place, or look it up each time you need it. Never share your account number with anyone you do not trust.
