Your account number is on your debit card, checks, and online banking
Your Bank of America account number is a 10-digit code that identifies your specific checking or savings account. You can find it in four places without calling the bank: on the front of your debit card (the last 10 digits), on the bottom left of any check you write, in the Account Details section of your online banking dashboard, or in the mobile app under Account Info.
The fastest route is your debit card if you have one. Look at the raised numbers on the front—the account number is the last 10 digits of the longer card number printed there. If you do not have a debit card or cannot locate it, your checks carry the same information in the MICR line (the small numbers at the bottom).
If you have neither checks nor a card in hand, log into your Bank of America account online or open the mobile app. The account number appears immediately in the Account Details or Account Information section—usually visible on the dashboard without clicking further.
Key Takeaways
- Your Bank of America account number is the last 10 digits printed on your debit card.
- Checks display your account number in the MICR line at the bottom left, after the routing number.
- Online banking and the mobile app show your account number in the Account Details section without requiring a phone call.
- The account number is different from your card number—the card number is longer and includes the account number as its final 10 digits.
- You will need your account number to set up direct deposit, wire money, or authorize ACH transfers.
Finding it on your debit card
The debit card method is the simplest if you have the card in your wallet. Look at the front of the card where the raised numbers are embossed. You will see a long string of digits—typically 16 numbers. Your account number is the last 10 digits of that string.
Write down only the last 10 digits, not the full card number. The first six digits identify Bank of America and the card type; the middle digits are check digits for security. Only the final 10 match your actual account.
If your debit card is lost, expired, or you never received one, move to the checks or online banking method instead of ordering a replacement card just to find your account number.
Finding it on a check
Every check you write contains your account number in the MICR line—the small, machine-readable numbers printed at the bottom of the check in a special font. The MICR line contains three separate numbers in this order: routing number, account number, and check number.
Look at the bottom left of the check. The first set of numbers (usually nine digits) is your routing number. The second set (usually 10 digits) is your account number. The third set on the right is the individual check number. Your account number is always in the middle position.
If you have old checks from a closed account, that account number will not work for current transactions. Use checks from your active account only.
Finding it in online banking or the mobile app
Log into your Bank of America account at bankofamerica.com or open the mobile app on your phone. Once you are signed in, your account number appears on the main dashboard or in a section labeled Account Details, Account Information, or Accounts.
On the website, look for your account name and balance—the account number is usually displayed directly below or next to it. In the mobile app, tap on the account you want, then look for Account Info or Details. The 10-digit account number will be visible without additional clicks.
This method works even if you have multiple accounts with Bank of America. Each account has its own unique 10-digit number, so make sure you are viewing the correct account before copying the number down.
What to do if you cannot find your account number
If you do not have access to a debit card, checks, or online banking, call Bank of America customer service at 1-800-432-1000. Have your Social Security number, date of birth, and a form of identification ready. A representative can confirm 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 print your account number for you on the spot, and this is often faster than a phone call if a branch is near you.
If you have recently opened your account and have not yet received checks or a debit card, online banking is your only self-service option. The account number will be there as soon as the account is active, even if your physical cards have not arrived yet.
Why you need your account number
Your account number is required for several common banking tasks. Setting up direct deposit for paychecks, government benefits, or tax refunds requires your account number and routing number. Authorizing ACH transfers—moving money between your Bank of America account and another bank—also requires it.
If you are paying a bill by phone or mail and the biller asks for your account number, they are asking for this 10-digit code, not your full debit card number. Providing only your account number (rather than your card number) is safer for transactions where the card itself is not being used.
Wire transfers, setting up automatic bill payments, and requesting a cashier's check may also require your account number. Keep it in a safe place separate from your debit card.
Frequently Asked Questions
Is my account number the same as my debit card number?
No. Your debit card number is 16 digits; your account number is 10 digits and makes up the last 10 digits of the card number. Never give out your full card number when only the account number is requested.
Do I need my routing number too?
Often yes. Direct deposit and ACH transfers require both your routing number and account number. Bank of America's routing number varies by state and account type, but you can find it in online banking or by calling 1-800-432-1000.
What if I have multiple Bank of America accounts?
Each account has its own unique 10-digit account number. In online banking or the app, you can see all your accounts listed separately, each with its own number. Make sure you copy the number from the correct account.
Can I use my account number to log into online banking?
No. Online banking requires your username and password, not your account number. Your account number is only for transactions and transfers, not for signing in.
Is it safe to share my account number?
Your account number alone cannot be used to withdraw money or make purchases, so it is safer to share than your full debit card number or PIN. However, only provide it to trusted sources like your employer (for direct deposit) or your bank.
