Your checking account number is printed on the bottom left of your checks, in your bank's online portal, or by calling your bank's customer service line
The account number is an eight- to twelve-digit code that identifies your specific checking account. It appears on every check you write, in your bank's mobile app or website, and on statements mailed to you. You do not need to visit a branch — most banks let you find it in seconds online or by phone.
If you have checks, look at the bottom of any check. You will see three groups of numbers: the routing number on the far left, your account number in the middle, and the check number on the right. The account number is usually nine digits, though some banks use eight or ten.
If you do not have checks or cannot locate them, log into your bank's website or app. Your account number appears on the account overview page, on statements, and often in the "Account Details" or "Account Information" section. Some banks also display it when you hover over your account name.

Finding your account number online
Log into your bank's website using your username and password. Most banks display your account number prominently on the dashboard or home page after you sign in. Look for a section labeled "Accounts," "Account Summary," or "My Accounts."
Click on the checking account you need. A details page will open showing your full account number, routing number, and recent transactions. Some banks hide the full number for security and show only the last four digits on the main page — click "View Full Account Number" or a similar link to see all digits.
If you use your bank's mobile app, the process is the same. Open the app, tap your checking account, and look for "Account Details" or an information icon. The account number will be displayed there.
Getting your account number by phone
Call the customer service number on the back of your debit card. This number connects you directly to your bank, not to a third party. Have your Social Security number or PIN ready so the representative can verify your identity.
Tell the representative you need your checking account number. They will read it to you over the phone. Write it down carefully, as you will need all digits to set up direct deposit, wire transfers, or automatic payments.
If you do not have your debit card, call the main phone number listed on your bank's website. The bank's website usually has a "Contact Us" page with routing numbers and phone numbers for different services.
Account number on checks and statements
Every check you write has your account number printed on it. Look at the bottom of the check. The numbers appear in this order: routing number (nine digits), account number (usually nine digits), check number (four or five digits). The account number is always in the middle.
Your monthly bank statement also lists your account number. Paper statements show it at the top or in the account information section. If you receive statements by email, open the PDF and look for "Account Number" near the top.
Deposit slips, if your bank still provides them, also print your account number. Some banks print it on the back of your debit card as well, though many do not for security reasons.
What to do if you cannot find your account number
If you have lost all checks, cannot access your online account, and do not have your debit card, visit your bank branch in person. Bring a photo ID and ask a teller for your account number. They will verify your identity and provide it immediately.
If you have forgotten your online banking password, use the "Forgot Password" link on your bank's website to reset it. You will usually receive a reset link by email within minutes. Once you reset your password, you can log in and find your account number.
If you cannot remember which bank holds your account, check your email for recent statements or payment confirmations. You can also search your email for "account statement" or the name of the bank you think you used. If you still cannot locate it, contact the bank directly with your name and address, and they can look up your account.
Keeping your account number secure
Your account number is needed for legitimate transactions like direct deposit, wire transfers, and bill payments. However, do not share it with anyone who contacts you by phone or email claiming to be from your bank. Real banks do not ask for your account number by phone or email.
When you provide your account number to set up a payment or transfer, make sure you are on your bank's official website or app, not a link from an email. Scammers sometimes send fake emails that look like they come from your bank but actually lead to fake websites designed to steal your information.
If you believe someone has your account number and may have used it fraudulently, contact your bank immediately. Most banks can freeze your account, issue a new account number, and investigate unauthorized transactions.
Frequently Asked Questions
Is my account number the same as my routing number?
No. Your routing number identifies your bank branch, while your account number identifies your specific account at that bank. Both appear on the bottom of your checks, with the routing number on the far left and the account number in the middle. You need both numbers to set up direct deposit or wire transfers.
Can I use my account number to transfer money to someone else?
Yes, but only if you also have their routing number. To send money by wire transfer or ACH transfer, you need both the recipient's account number and their bank's routing number. Your bank's website or app will have a section for transfers where you enter both pieces of information.
What if my account number has changed?
If your bank merged with another bank or closed your branch, your account number may have changed. Check your most recent statement or log into your online account to see your current number. If you are unsure, call your bank's customer service line and ask whether your account number is still the same.
Do I need my account number to use my debit card?
No. Your debit card has its own card number printed on the front, which is different from your account number. You use the card number for purchases and ATM withdrawals. Your account number is only needed for transfers, direct deposit, and bill payments.
Can someone access my account with just my account number?
Not easily. Your account number alone is not enough to withdraw money or make transfers. Most banks require additional verification like your PIN, password, or Social Security number. However, do not share your account number with strangers, as it is one piece of information a scammer could use in combination with other details to commit fraud.
