The quickest way to find your account number
Your bank account number is printed on the bottom left of every check you have, right after the routing number. If you have checks, look at the first set of numbers after the small box on the lower left edge — that's your account number, usually 10 to 12 digits long.
If you don't have checks or can't find them, log into your bank's website or mobile app. Your account number appears on your account summary or dashboard, usually near your account name and balance. You can also call your bank's customer service number (on the back of your debit card or on your bank statement) and ask them to read it to you over the phone.
Your bank statement — whether you get it by mail or email — also lists your account number at the top or in a section labeled "Account Information." This is often the easiest place to find it if you're already looking at your statement.

Finding your account number on your debit card
Your debit card does not print your full account number on it. The card shows a different number — the card number — which is used for purchases and ATM withdrawals, but it is not the same as your bank account number.
This is intentional. Your account number is what you give to employers for direct deposit or to other banks for wire transfers. Your card number is what you use for everyday transactions. Keeping them separate protects your account if your card is lost or stolen.
Locating your account number in online banking
Log into your bank's website or app using your username and password. Once you're signed in, look for a section called "Account Summary," "My Accounts," "Account Details," or "Account Information" — the exact name varies by bank.
Click on that section and you'll see a list of your accounts. Next to each account name, your account number will be displayed. Some banks show the full number; others show only the last four digits on the main screen but reveal the full number when you click on a specific account.
If you can't find it in these obvious places, look for a link that says "Account Details" or "View Full Account Number." Some banks also let you read your account information as a PDF, which will include your account number.
Reading your account number from a bank statement
Open your most recent bank statement, whether it arrived by mail or email. At the top of the statement, usually in a box or section labeled "Account Information" or "Your Account," you'll see your account number printed clearly.
The statement also shows your routing number nearby, often labeled separately. Both numbers appear on every statement your bank sends you, so if you've kept any statements from the past few months, you can find your account number in any of them.
What to do if you can't find your account number
Call your bank directly. The phone number is on the back of your debit card, on any bank statement, or on your bank's website. Tell the representative you need your account number, and they'll read it to you after verifying your identity with your name, address, or the last four digits of your Social Security number.
You can also visit a branch in person with a photo ID. A teller can print your account number for you or write it down on a piece of paper. This is a free service — banks provide account numbers to their own customers without charge.
If you've recently opened an account, check your welcome packet or the email confirmation you received when you opened the account. New account paperwork often includes your account number.
Why you need your account number and when to share it
Your account number is needed for direct deposit from an employer, for setting up automatic bill payments, and for wire transfers to or from your account. You'll also need it if you're sending money to someone else's account or receiving a transfer from another bank.
It's safe to share your account number with your employer, your bank, or other financial institutions. However, never share your account number with someone you don't know or trust, and never share it in response to an unsolicited email or phone call. Legitimate banks and employers will never ask for your account number via email or text message.
Your account number alone is not enough for someone to steal money from your account — they would also need your routing number and usually some form of authorization. Still, treat your account number like you would any other financial information: share it only when necessary and only with people or organizations you know.
Frequently Asked Questions
Is my account number the same as my card number?
No. Your card number is the 16-digit number printed on the front of your debit card. Your account number is a separate number, usually 10 to 12 digits, that identifies your bank account. You can find your account number on your checks or bank statement, but not on your card.
Can someone access my account with just my account number?
Your account number alone is not enough for someone to transfer money or make withdrawals. They would also need your routing number and usually some form of authorization or access to your online banking login. Still, don't share your account number with people you don't know or trust.
What if I have multiple accounts at the same bank?
Each account has its own account number. When you log into online banking, you'll see all your accounts listed separately, each with its own number. Your bank statement will also show which account number the statement covers at the top of the page.
Do I need my account number to use an ATM?
No. You use your debit card and PIN to withdraw money at an ATM. Your account number is not required for ATM transactions. You only need your account number when setting up direct deposit, making transfers between banks, or paying bills by bank transfer.
