Where to find your account number
Your Bank of America account number is printed on the bottom left of every check you write. If you have checks, open your checkbook and look at the string of numbers below the routing number — that's your account number, usually 10 digits long.
If you don't have checks or prefer not to dig through a checkbook, you can find it in seconds through your online banking portal. Log into your Bank of America account at bankofamerica.com, click on the account you want, and the account number appears at the top of the page or in the account details section. The mobile app shows it the same way — tap the account, then look for account information or details.
You can also call Bank of America customer service at 1-800-432-1000 and give them your Social Security number and PIN to verify your identity. They'll read your account number to you over the phone. This route takes longer but works if you're away from your computer or phone.
Key Takeaways
- Your account number is on the bottom left of any check you own, printed as a 10-digit number after the routing number.
- Log into bankofamerica.com or the mobile app to see your account number instantly without writing a check.
- Call 1-800-432-1000 if you need your account number read to you, but have your Social Security number and PIN ready to verify who you are.
- Account numbers are different from routing numbers — your routing number is the same for all Bank of America customers in your region, but your account number is unique to you.
Why you need your account number
You'll need your account number when you set up direct deposit for paychecks or government payments, arrange automatic bill payments, or receive a wire transfer. Banks and employers use it to make sure money lands in the right account. Without it, a payment can be delayed or sent to the wrong place.
You also need it if you're transferring money between your own accounts at different banks, or if you're sending money to someone else and they ask for your details. Some services ask for both your routing number and account number together — the routing number tells the system which bank, and the account number tells it which account at that bank.
Keeping your account number safe
Your account number is not as sensitive as your PIN or password, but you should still treat it with care. Share it only with people or organizations you trust — your employer, your bank, a business you're paying, or someone you're sending money to. Don't post it on social media or give it to someone who calls you unexpectedly.
Scammers sometimes call pretending to be from your bank and ask for your account number to "verify" your account. Bank of America will never call you asking for this information. If someone calls claiming to be from the bank, hang up and call the number on the back of your card instead.
What to do if you forget your account number
Forgetting your account number is not an emergency. You have several quick ways to find it again. The fastest is to log into your online account or app — it takes 30 seconds. If you're away from a computer, text a photo of a check to yourself or call the customer service line.
If you've lost all your checks and can't access online banking, call 1-800-432-1000. Have your Social Security number, date of birth, and the phone number on file ready. The representative will verify your identity and give you your account number. The whole call usually takes under five minutes.
Account number vs. routing number
These two numbers work together but mean different things. Your routing number identifies Bank of America itself and the specific branch or region where your account lives. All Bank of America customers in the same area share the same routing number. Your account number is unique to you — it's the specific account within the bank.
When you set up direct deposit or a wire transfer, you'll need both. The routing number tells the sending bank where to send the money, and the account number tells that location which account to put it in. If you give only one, the transaction will fail or be delayed.
Finding your account number on statements
If you receive paper statements in the mail, your account number is printed at the top of every statement. It's also in the top right corner, sometimes labeled as "Account Number" or "Acct #." Digital statements you download from your online account show it the same way.
Statements are useful if you need to reference your account number for a record — you can keep one in a safe place at home. But for speed, logging into your account online or checking a check is faster than waiting for or searching through old statements.
Frequently Asked Questions
Is my account number the same across all my Bank of America accounts?
No. Each account you have — checking, savings, money market — gets its own unique account number. If you have multiple accounts, you'll see a different number for each one when you log in or look at the checks for that account.
Can someone steal money from my account if they know my account number?
Knowing your account number alone is not enough to steal from you. A thief would also need your routing number, and more importantly, access to your online banking login or the ability to forge documents. Never give your account number to someone you don't trust, but if it's accidentally shared, contact Bank of America and they can monitor your account for fraud.
What if the account number on my check doesn't match what's shown online?
Contact Bank of America immediately. A mismatch usually means a printing error on the checks, and you should order new ones. Call 1-800-432-1000 or visit a branch to report it and request replacement checks.
Do I need my account number to log into online banking?
No. You log in with your username and password or your online ID. Once you're logged in, you can see your account number. You don't need it to access your account.
