Your account number is printed on the bottom left of your checks and visible in the online banking portal
Your Bank of America account number is a unique identifier for your specific account. You can find it in three places: on a paper check, in the Bank of America mobile app or website, or by calling customer service. The fastest method depends on whether you have immediate access to your account or need help from a representative.
The account number itself is typically 10 digits long and appears on the bottom left of any check you have from that account. If you do not have checks available, logging into your online account takes seconds and shows the number clearly on your account details page.
Key Takeaways
- Your account number appears on the bottom left of your checks, printed after the routing number.
- Log into your Bank of America account online or through the mobile app to see your account number under account details or account information.
- Call Bank of America customer service at 1-800-432-1000 if you cannot access your account or do not have checks available.
- You will need your account number to set up direct deposit, wire money, or provide banking details to employers or creditors.
Finding your account number on a check
If you have a checkbook, the account number is printed on the bottom of every check. Look at the bottom left corner of the check. You will see three sets of numbers separated by colons or vertical lines. The first set is your bank's routing number (nine digits), the second set is your account number (typically 10 digits), and the third set is the check number.
The account number is always the middle set of numbers on the bottom of the check. Write it down or take a photo if you need to reference it later. This method works even if you have not used the checks yet—the numbers are printed the same way on every check in your book.
Checking your account number online
Log into your Bank of America account at bankofamerica.com using your username and password. Once you are logged in, look for a section labeled "Account Details," "Account Information," or "Accounts." Your account number will be displayed there alongside your account type (checking, savings, money market, and so on).
In the Bank of America mobile app, tap the account you want to view, then look for an information icon or "Details" option. Your account number will appear on that screen. You can also take a screenshot or note the number for future reference. This method works whether you have checks or not.
Getting your account number by phone
Call Bank of America customer service at 1-800-432-1000. A representative will ask you to verify your identity using information like your Social Security number, date of birth, or answers to security questions you set up when you opened the account. After verification, they will provide your account number and answer any other questions about your account.
Wait times vary depending on the time of day and day of the week. Calling early in the morning on a weekday typically means shorter hold times. Have your ID ready so the verification process moves faster.
Why you need your account number
Your account number is required for several common banking tasks. Employers need it to set up direct deposit of your paycheck. Creditors, loan servicers, and utility companies need it to process payments from your account. If you are sending or receiving a wire transfer, both your routing number and account number are necessary. Some bill payment services also require your account number to pull funds from your Bank of America account.
Keep your account number private the same way you would protect your debit card or PIN. Do not share it in unsolicited emails or texts, and do not post it on social media. Legitimate businesses you already work with—your employer, your bank, a creditor you owe—will ask for it directly when needed.
Difference between account number and routing number
Your account number identifies your specific account at Bank of America. Your routing number identifies Bank of America itself as the financial institution. Bank of America's routing number is 026009593 for most accounts, though some specialty accounts may have a different routing number. You need both numbers together to complete wire transfers, set up direct deposit, or authorize ACH payments.
When you provide banking information to an employer or creditor, they will ask for both numbers. Your account number changes only if you close the account and open a new one. Your routing number stays the same as long as you bank with Bank of America at the same branch type (online, in-person, and so on).
What to do if you cannot find your account number
If you do not have checks and cannot log into your online account, calling customer service is your fastest option. Have your ID ready and be prepared to answer security questions. If you are locked out of your account due to a forgotten password, you can reset it on the Bank of America website before calling—this will let you access your account number yourself without waiting on hold.
If you suspect fraud or unauthorized access to your account, tell the customer service representative immediately. They can freeze your account, review recent transactions, and help you secure it before providing your account number or other sensitive details.
Frequently Asked Questions
Can I change my account number?
No, your account number is permanent for that account. If you close the account and open a new one, you will receive a new account number. Changing your account number is not something Bank of America offers, and no legitimate reason exists to do so.
Is it safe to give my account number to someone?
Your account number alone cannot be used to withdraw money or make purchases. However, combined with your routing number, it can be used to set up ACH transfers or direct deposit. Only provide both numbers to people or organizations you trust and have initiated contact with yourself.
What if my account number appears on a check I lost?
Call Bank of America at 1-800-432-1000 to report the lost check. They can cancel that check number so it cannot be cashed. Your account number itself does not need to be changed, but the specific check is now inactive.
Do I need my account number to use my debit card?
No, your debit card works with your PIN and card number. Your account number is separate and is only needed when you are providing banking details directly—for direct deposit, bill payments, or wire transfers.
Where is the account number on a Bank of America debit card?
Your account number does not appear on your debit card. The card shows a card number (16 digits), expiration date, and CVV, but not your account number. You must check a check, your online account, or call customer service to find your account number.
