The fastest way to find your account number
Your bank account number is printed on the bottom left of every check you write — it comes after the routing number and before the check number. If you have checks, that is the quickest place to look. The format is usually nine or ten digits, though it varies by bank.
If you do not have checks in front of you, log into your bank's website or mobile app. Your account number appears on the account overview page, often labeled "Account Number" or "Account Details." Most banks show it prominently near your account balance.
You can also call your bank's customer service line — the number is on the back of your debit card or on your bank statements — and ask a representative to read it to you. Have your ID ready, as they will verify your identity before sharing account information.

Finding it on your bank statements
Paper statements sent by mail show your account number near the top, usually in the upper right corner or in a section labeled "Account Information." The number appears on every statement your bank sends, so if you have received mail from your bank in the past few months, you can find it there.
If you have switched to paperless statements, log into your online banking portal and download a recent statement as a PDF. The account number will be in the same location as it appears on printed statements. You can also request a paper copy from your bank if you need a physical record.
Using your debit card or online banking
Your debit card does not print your full account number on the front — it shows only a partial number for security reasons. However, your bank's mobile app or website will display the complete account number once you log in.
Open your bank's app, tap on the account you want to check, and look for a section that says "Account Details" or "Account Information." Some banks require you to tap an additional button or link to reveal the full number. If you cannot find it in the app, the website version usually makes it easier to locate.
What to do if you cannot access your account online
If you have forgotten your password or cannot log into your bank's website or app, call the customer service number on your debit card or a recent statement. A representative can reset your password and help you regain access to your account information.
If you do not have a debit card or recent statements, visit a branch in person with a photo ID. A teller can look up your account number and provide it to you immediately. Bring your ID and be prepared to answer security questions to confirm your identity.
Account numbers for different account types
If you have multiple accounts at the same bank — such as a checking account, savings account, and money market account — each one has its own unique account number. When you log into your online banking, you will see all your accounts listed separately, each with its own number.
Make sure you are looking at the correct account when you need the number for a specific purpose, such as setting up a direct deposit or making a transfer. Mixing up account numbers can send money to the wrong place, so double-check before you provide the number to an employer, government agency, or other organization.
Keeping your account number secure
Your account number is not as sensitive as your PIN or password, but you should still treat it with care. Do not share it with people you do not trust, and be cautious when providing it over the phone unless you initiated the call to a number you know is legitimate.
Scammers sometimes call claiming to be from your bank and ask for your account number. If someone calls you unexpectedly asking for this information, hang up and call your bank directly using the number on your debit card or statement. Your bank will never ask for sensitive information in an unsolicited call.
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 (usually nine digits) and your account number second.
Can I find my account number on my debit card?
No, your debit card shows only a partial account number for security. To see your full account number, check your checks, bank statements, or log into your online banking account.
What if I have an old account number from a closed account?
Old account numbers cannot be reused. If you closed an account and opened a new one, your new account will have a different number. Use only the current account number for any transactions or direct deposits.
Do I need my account number to use my debit card?
No. Your debit card works with just the card number, expiration date, and CVV. You need your account number only when setting up direct deposits, wire transfers, or other bank-to-bank transactions.
Can I change my account number?
Most banks do not allow you to change your account number. If you are concerned about security, contact your bank to discuss your options. In rare cases, they may close your account and open a new one with a different number.
