Your account number is on your debit card, checks, and online banking
Your Bank of America checking account number is a 10-digit code that identifies your specific account. You can find it in four places without calling the bank: on your debit card, on any check you have, in the Bank of America mobile app, or on the Bank of America website after you log in.
The fastest route is usually your debit card. Look at the front or back — the account number appears as a separate sequence from the card number itself. If you do not have your card handy, a check from your checkbook shows the same number in the bottom left corner, printed between two colons.
If you have neither a card nor checks, you can view your account number online in seconds by logging into your Bank of America account through the website or app.
Key Takeaways
- Your 10-digit account number appears on your debit card, checks, and in your online banking portal — you do not need to call the bank to find it.
- On a check, the account number is the middle sequence of three numbers at the bottom, printed between colons.
- On your debit card, the account number is separate from the 16-digit card number and may appear on the front or back depending on your card design.
- Logging into your Bank of America account online or through the mobile app shows your account number under account details or account information.
Finding your account number on your debit card
Your Bank of America debit card displays your account number separately from your card number. The card number is the long 16-digit sequence on the front. Your account number is shorter — 10 digits — and appears either on the front below the card number or on the back near the signature strip, depending on your card design.
If you cannot locate it on the card itself, the back of the card usually has a customer service number you can call, and a representative can read the account number to you over the phone. However, checking online or looking at a check is faster and does not require a call.
Finding your account number on a check
Every check from your Bank of America checking account prints your account number at the bottom. Look at the bottom left corner of any check. You will see three separate sequences of numbers, each separated by a colon or vertical line.
The format is: routing number : account number : check number. Your account number is the middle sequence — the one between the first and third numbers. It is always 10 digits long. This method works even if your debit card is lost or damaged, as long as you have at least one check from your checkbook.
Finding your account number in online banking
Log into your Bank of America account at bankofamerica.com or through the mobile app. Once you are signed in, navigate to the account details or account information section. This is usually found by tapping your account name or selecting "Account Details" from the menu.
Your account number will be displayed in full. Some versions of the app show it under "Account Information" when you select your checking account from the list. If you cannot find it when ready, the search function within the app can help you locate "account number" quickly.
What to do if you cannot find your account number
If you do not have access to a debit card, checks, or online banking, you can call Bank of America customer service at 1-800-432-1000. Have your Social Security number and a form of identification ready. A representative will verify your identity and provide your account number over the phone.
You can also visit a Bank of America branch in person with a government-issued ID. A teller can look up your account number and write it down for you. This is useful if you need the number when ready and prefer not to use the phone or online services.
Why you need your account number and when to use it
Your account number is required for setting up direct deposit, arranging wire transfers, paying bills through your bank, and providing to employers or other institutions that need to deposit money into your account. It is also needed if you want to link your Bank of America account to another bank or financial service.
Keep your account number separate from your debit card and PIN. While your account number alone cannot be used to withdraw money, it is still sensitive information. Do not share it with anyone unless you initiated the request or are certain the recipient is legitimate.
The difference between your account number and card number
Your account number and card number are two different things. Your card number is the 16-digit number on the front of your debit card — this is what you use to make purchases or withdraw cash. Your account number is a 10-digit code that identifies your checking account at the bank itself.
You may have multiple debit cards linked to the same account, but you will have only one account number per checking account. If you close your checking account and open a new one, you will receive a new account number, but a replacement debit card for the same account will have the same account number printed on it.
Frequently Asked Questions
Is my account number the same as my routing number?
No. Your routing number identifies Bank of America as the bank, and your account number identifies your specific account within that bank. Both appear at the bottom of your checks, but in different positions. The routing number comes first, the account number is in the middle, and the check number is last.
Can someone use my account number to steal money from my account?
Your account number alone cannot be used to withdraw money or make purchases. However, combined with other information like your routing number, it can be used to set up unauthorized transfers or payments. Do not share your account number with people or websites you do not trust.
What if my account number is different on my debit card than on my checks?
This should not happen. If the numbers do not match, contact Bank of America when ready. It may indicate a printing error or a problem with one of the items. A representative can confirm which number is correct for your account.
Do I need my account number to use my debit card at a store or ATM?
No. You only need your card number, PIN, or signature depending on how you are paying. Your account number is used for banking transactions like direct deposit or wire transfers, not for everyday card use.
