Your account number is printed on the bottom left of your checks, in your bank's mobile app, and on statements mailed to you

The fastest way to find your account number is to look at a check from your checking account. The account number appears on the bottom of the check, after the routing number and before the check number. If you do not have checks handy, log into your bank's website or mobile app — your account number will appear on the account overview or dashboard page, usually near your account type and balance.

If you cannot access your app or website, call your bank's customer service number on the back of your debit card or on your most recent bank statement. A representative can read your account number to you over the phone. You will need to verify your identity first, usually by providing your Social Security number, date of birth, or answers to security questions you set up when you opened the account.

Key Takeaways

  • Your account number appears on the bottom left of any check you have, printed between the routing number and the check number.
  • Bank statements, whether mailed or viewed online, display your account number on the first page or in the account details section.
  • Your bank's mobile app shows your account number on the main account screen without requiring you to log into a website.
  • If you cannot locate it yourself, call the customer service number on your debit card or statement and a representative will provide it after you verify your identity.

Finding your account number on a check

A standard check has three numbers printed along the bottom in magnetic ink. From left to right, they are: routing number (nine digits), account number (typically 10 to 12 digits), and check number (usually four to five digits). Your account number is the middle set of numbers. This layout is the same across most U.S. banks, so the position is reliable even if the font or spacing differs slightly.

If you have an old check from years ago, the account number should still be correct — banks do not change account numbers unless you close and reopen the account. However, if you recently switched banks or merged accounts, make sure the check is from your current bank and current account.

Locating it in your online banking or app

Log into your bank's website or open the mobile app on your phone. Most banks display your account number prominently on the account overview page, which is usually the first screen you see after logging in. Look for a section labeled "Account Details," "Account Information," or simply your account name (such as "Checking" or "Savings").

Some banks hide the full account number behind a "Show" or "Reveal" button for security reasons — you may need to click to display it. If you have multiple accounts at the same bank, make sure you are viewing the correct one. The account number for a savings account differs from the account number for a checking account, even though they are linked to the same person.

Checking your bank statement

Paper statements mailed to your address and electronic statements you can view online both include your account number. On a paper statement, look at the top section where your name and address appear — the account number is usually printed there, often labeled "Account Number" or "Acct #." On an electronic statement, the account number typically appears on the first page in the same location.

If you no longer receive paper statements, you can still view electronic statements through your online banking portal. Go to the "Statements" or "Documents" section, select the most recent month, and download or view the PDF. The account number will be in the same place as it would be on a paper statement.

Calling your bank directly

If you do not have a check, cannot access your online account, or prefer to speak with someone, call the customer service number printed on the back of your debit card. This is the most direct route. Have your Social Security number, date of birth, and the last four digits of your debit card ready — the bank will ask for these to confirm your identity before providing your account number.

Wait times vary depending on the time of day and how busy the bank is. Calling early in the morning on a weekday typically means shorter waits. Some banks also offer account information through their automated phone system — you may be able to press buttons to hear your account number read aloud without speaking to a representative, though this varies by bank.

What to do if you cannot find it

If you have tried the above methods and still cannot locate your account number, the issue is usually that you are looking in the wrong account or at an old statement from a closed account. Double-check that you are using the correct bank and the correct account type (checking versus savings).

If you recently opened the account, the account number may not appear on your first statement or in your app for a few business days. Contact your bank to confirm the account is fully activated. If you opened the account online, check your email for a welcome message that may include your account number.

Why you need your account number

Your account number is required when you set up direct deposit, arrange wire transfers, or provide banking information to a third party such as an employer or insurance company. It is also needed when you contact your bank about a specific transaction or account issue. The account number, combined with your routing number, uniquely identifies your account and ensures money goes to the right place.

Keep your account number in a safe place, but do not share it with people you do not trust. Scammers sometimes use account numbers to attempt unauthorized transactions, though your routing number and account number alone cannot be used to withdraw money without additional verification. If you suspect fraud, contact your bank immediately.

Frequently Asked Questions

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

No. Your debit card number is a 16-digit number printed on the front of your card. Your account number is typically 10 to 12 digits and is not printed on the card itself. They are separate identifiers linked to the same account.

Can someone steal money using just my account number?

Your account number alone is not enough to withdraw money. A person would also need your routing number and would typically need additional verification such as your PIN or a one-time code. However, do not share your account number with people you do not trust, as it is one piece of information a scammer could use in combination with other data.

What if my account number changed?

Account numbers do not change unless you close your account and open a new one. If you believe your account number has changed, contact your bank to confirm. You may be confusing it with a different account or looking at a statement from a closed account.

Do I need both my routing number and account number to receive a direct deposit?

Yes. Your employer or the organization sending the deposit will ask for both your routing number and account number. The routing number identifies your bank, and the account number identifies your specific account within that bank. Both are required for the deposit to reach the correct place.
