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

The fastest way is to look at a check from your checking account. The account number appears at the bottom, after the routing number and before the check number. If you do not have checks, log into your bank's website or mobile app — your account number is usually displayed on the dashboard or in an account details section. You can also call your bank's customer service line and they will read it to you after you verify your identity.

Your account number is typically 8 to 12 digits long, though this varies by bank. It identifies your specific account at that bank, separate from any other accounts you hold there. You will need it for direct deposits, wire transfers, setting up automatic bill payments, and when you contact your bank about a specific account.

Key Takeaways

  • Your account number appears at the bottom of any check you have, printed after the routing number.
  • You can find it by logging into your bank's website or app and looking at your account details or dashboard.
  • Calling your bank's customer service number and verifying your identity will get you the number over the phone.
  • Your account number is different from your routing number — you need both for transfers and direct deposits.

Finding it on a paper check

If you have a checkbook, pull out any check. At the bottom of the check, you will see three groups of numbers separated by colons or vertical lines. The first group is your routing number. The second group is your account number. The third group is the check number itself.

The account number is usually 8 to 12 digits. Write it down exactly as it appears — do not add or remove any zeros. If your checks are very old or from a different account, make sure you are looking at a check from the account you actually need the number for.

Finding it online or in your mobile app

Log into your bank's website using your username and password. Most banks display your account number on the main dashboard or home page, often labeled "Account Number" or "Account Details." If you do not see it there, look for a section called "Accounts," "My Accounts," or "Account Information." Click into the specific account you need the number for.

In the mobile app, the process is the same. Open the app, log in, and look at the account summary. The account number is usually visible at the top or in a details section. Some banks require you to tap or swipe to reveal the full number for security reasons — you may see only the last four digits until you take that action.

Getting it by phone

Call the customer service number on the back of your debit card or on your bank statement. Have your Social Security number, date of birth, and the answer to any security questions ready. The representative will verify your identity and then read your account number to you.

This method works if you have lost your checks and cannot access online banking. It also works if you are trying to find the account number for a savings account, money market account, or other account type that may not have checks associated with it.

What to do if you cannot find it

If you do not have checks, cannot log into your online account, and do not have access to a phone, you can visit your bank in person with a photo ID. A teller can look up your account number and write it down for you. This is the slowest option but works in any situation.

If you are trying to find the account number for a joint account or an account held in someone else's name, you will need that person's permission and may need to be present or provide written authorization. Banks have different rules about who can request this information.

Account number versus routing number

Your account number and routing number are not the same thing. The routing number identifies your bank — it is the same for all customers at that bank. Your account number identifies your specific account within that bank. You need both pieces of information to set up direct deposit, receive a wire transfer, or authorize automatic payments.

When you give out your account number, you are telling someone which account at your bank to send money to or pull money from. When you give out your routing number, you are telling them which bank to contact. Together, they form a complete address for your money.

Keeping your account number safe

Your account number is not as sensitive as your PIN or password, but you should still treat it with reasonable care. It appears on every check you write, so anyone who receives a check from you will see it. However, do not share your account number with people you do not trust, and do not post it on social media or in public forums.

If you suspect someone has your account number and may misuse it, contact your bank when ready. They can monitor the account for unauthorized activity and issue you a new account number if necessary, though this is rare.

Frequently Asked Questions

Is my account number the same as my card number?

No. Your debit or credit card number is different from your bank account number. The card number is printed on the front of your card. Your account number is at the bottom of your checks or in your online banking portal. They are separate identifiers.

Can I find my account number on my bank statement?

Yes. Most bank statements show your account number at the top or in a header section. If you receive paper statements in the mail, look at the top of the first page. If you view statements online, it is usually displayed near the account name or in the account details area.

What if I have multiple accounts at the same bank?

Each account has its own unique account number. When you log into online banking, you will see all your accounts listed separately, each with its own number. Make sure you are looking at the correct account before you write down or share the number.

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 not required. You only need your account number when you are setting up transfers, direct deposits, or payments outside of your bank's system.

Can someone take money from my account if they have my account number?

Not easily. Your account number alone is not enough to transfer money out. Most banks require additional verification — a PIN, password, or authorization from you — before they will move money. However, contact your bank when ready if you believe your account number has been compromised.
