Your checking account number is printed on the bottom left of your checks, in your bank's online portal, or by calling your bank's customer service line.

The easiest place to look is the bottom of any check you have. The account number appears after the routing number and is typically 8 to 12 digits long. If you don't have checks on hand, log into your bank's website or mobile app — your account number is almost always visible on the account overview or dashboard page. If you can't access online banking, call the phone number on the back of your debit card or on your bank's website and a representative can read it to you in seconds.

You'll need your account number when setting up direct deposit, making wire transfers, paying bills through your bank, or providing banking details to an employer or government agency. Having it readily available saves time when you're filling out forms or making financial arrangements.

Finding your account number on a check

Look at the bottom of any check in your checkbook. You'll see three sets of numbers printed in magnetic ink. The first set (usually 9 digits) is your bank's routing number. The second set, which comes right after the routing number, is your account number. The third set is the check number itself.

The account number is the middle group and is typically between 8 and 12 digits depending on your bank. Write it down or take a photo of the check so you have it when you need it. If your checks are old or faded, the numbers may be hard to read — in that case, use one of the other methods below.

Locating your account number online

Log into your bank's website or mobile app using your username and password. Once you're logged in, look for a page labeled "Account Overview," "Account Summary," "My Accounts," or "Dashboard." Your checking account number is almost always displayed prominently on this page, often near your account balance.

Some banks also list the account number in a section labeled "Account Details" or "Account Information." If you have multiple accounts with the same bank, make sure you're looking at the correct checking account — savings accounts and money market accounts have different numbers. Take a screenshot or write down the number so you have it saved separately from your phone or computer.

Calling your bank to get your account number

If you don't have checks or online access, call your bank directly. The phone number is printed on the back of your debit card, on your most recent bank statement, or on your bank's website. Have your identification ready — the representative will ask for your name, date of birth, and possibly the last four digits of your Social Security number to verify your identity.

Once verified, the representative will read your account number to you over the phone. This process usually takes less than a minute. Write down the number as they read it to you, or ask them to repeat it so you can confirm you have it correct.

What to do if you can't find your account number

If you've checked your checks, your online account, and called your bank but still can't locate the number, contact your bank's customer service again and explain the situation. Ask them to mail you a statement or send the account number by email (though some banks won't email sensitive information for security reasons). You can also visit a branch in person with your ID and ask a teller to provide it.

If you're in a hurry and need the number immediately, calling remains the fastest option. Have your ID information ready so verification takes only a few minutes.

Account numbers for different types of checking accounts

Whether you have a basic checking account, a high-yield checking account, a student checking account, or a business checking account, the account number works the same way. Each account type has its own unique account number, so if you have more than one checking account at the same bank, they will have different numbers.

If you're switching banks or opening a new account, your new bank will assign you a new account number. Your old account number becomes inactive once you close that account, so you won't be able to use it for future transactions.

Keeping your account number safe

Your account number is sensitive financial information. Don't share it with anyone unless you're certain they're legitimate — such as your employer for direct deposit, a government agency requesting it for a refund or payment, or a business you're paying intentionally. Scammers sometimes call or email claiming to be from your bank and ask for your account number; your bank already has this information and will never ask you for it unsolicited.

If you write down your account number, store it in a secure place. If you take a photo of a check, consider deleting it once you've used the information. Be especially cautious if you're providing your account number online — make sure you're on your bank's official website or app, not a phishing site designed to look like your bank.

Frequently Asked Questions

Is my account number the same as my routing number?

No. Your routing number identifies your bank, while your account number identifies your specific account at that bank. Both appear on the bottom of your checks, with the routing number first and the account number second. You need both numbers for wire transfers and some other transactions.

Can I use my debit card number instead of my account number?

No. Your debit card number is different from your account number. Some transactions require your account number specifically — like setting up direct deposit or making a wire transfer. Your debit card number is for card purchases and ATM withdrawals.

What if I have multiple checking accounts at the same bank?

Each account has its own unique account number. When you log into online banking, you'll see all your accounts listed separately. Make sure you're using the correct account number for the account you intend to use. If you're unsure which is which, call your bank and ask them to confirm which number belongs to which account.

Do I need my account number to check my balance?

No. You can check your balance by logging into online banking with your username and password, calling your bank's automated phone line, or visiting an ATM. You only need your account number when you're making a transaction that requires it, like setting up direct deposit or a wire transfer.

What should I do if I think someone has my account number?

Contact your bank immediately by calling the number on your debit card or a recent statement. Tell them you believe your account number may have been compromised. Your bank can monitor your account for suspicious activity and may issue you a new account number if necessary. In most cases, your bank's fraud protection covers unauthorized transactions.
