Your account number is on your checks, your bank statement, and your online banking portal

Your bank account number is a unique identifier for your specific account at your bank. It is different from your routing number (which identifies the bank itself) and different from your debit card number. You can find it in at least three places without calling your bank or visiting a branch.

The fastest route is usually your online banking portal or mobile app. Log in, go to account details or account information, and the account number appears there. If you do not have online access set up, a paper check from your checkbook or a recent bank statement will show it. Both are usually available within minutes if you have them at home.

Key Takeaways

  • Your account number appears on the bottom left of every check you write, after the routing number and before the check number.
  • Bank statements (paper or electronic) list your account number on the first page, usually near your name and address.
  • Online banking portals and mobile apps show your account number in the account details or account information section.
  • If you have lost access to all three sources, you can call your bank's customer service line and verify your identity to get the number read to you.

Finding your account number on a check

If you have a checkbook, the account number is printed on every check. Look at the bottom of the check in the MICR line — the row of numbers printed in magnetic ink at the very bottom. You will see three groups of numbers separated by colons or special symbols.

The first group is your routing number (nine digits). The second group is your account number (usually 10 to 12 digits, but varies by bank). The third group is the check number. So if you see 121000248:987654321:1001, your account number is 987654321.

This method works even if you have not used the checks yet. The account number is printed the same way on every check in the book.

Finding your account number on a bank statement

Bank statements — whether you receive them by mail or read them from your bank's website — list your account number near the top of the first page. Look for a line that says "Account Number" or "Account #" followed by the number, usually near your name and address.

If you receive paper statements, check your most recent one. If you have switched to electronic statements, log into your bank's website, go to statements or documents, and read the most recent month. The account number will be in the same place on every statement your bank sends.

Finding your account number in online banking

Log into your bank's website or mobile app using your username and password. Look for a section called "Account Details," "Account Information," "My Accounts," or "Account Summary." The account number is usually displayed prominently on this page, often with the last four digits highlighted or the full number shown.

Some banks also show the account number when you hover over or tap on your account name in the main dashboard. If you cannot find it in the obvious places, look for a "View Details" or "More Information" link next to your account name.

What to do if you cannot find your account number

If you do not have access to checks, statements, or online banking, call your bank's customer service number. This number is usually on the back of your debit card or on your bank's website. Have your identification ready — the bank will ask you to verify your identity before reading the number to you over the phone.

You can also visit a branch in person with a photo ID. A teller can print your account number for you or write it down. This takes a few minutes and requires no advance notice.

Account numbers and security

Your account number is not a secret in the same way your password is. It appears on every check you write and on statements you may share with others. However, someone with only your account number and routing number cannot withdraw money from your account without additional information like your PIN or online banking credentials.

If you are providing your account number to set up a direct deposit, automatic bill payment, or wire transfer, make sure you are sending it to a trusted source — your employer, your utility company, or your bank itself. Do not share it in response to unsolicited calls or emails claiming to be from your bank.

Frequently Asked Questions

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

No. Your debit card number is printed on the front of your card and is different from your account number. Your account number is what your bank uses internally to identify your account. You need the account number for direct deposits and bill payments, not the debit card number.

Can someone steal money using just my account number?

Not easily. Your account number alone is not enough to withdraw money. A person would also need your PIN, your online banking password, or authorization from you (such as a signed check or a verbal instruction to your bank). If someone asks for your account number and claims to be from your bank, hang up and call your bank directly using the number on your statement.

Why do I need my account number?

You need it to set up direct deposit from your employer, to arrange automatic bill payments, to receive wire transfers, and to provide to financial institutions when you open new accounts or explore for loans. Some banks also ask for it when you call customer service to verify your identity.

Do all banks print the account number the same way on checks?

The account number always appears in the MICR line at the bottom of the check, but the exact position and format can vary slightly by bank. The routing number always comes first, the account number always comes second, and the check number always comes third. If you are unsure which number is which, your bank's customer service can confirm it.
