Check your bank statements or debit card
Your bank account number appears on almost every piece of paper your bank sends you. Open your most recent bank statement — the one mailed to your home or the one you download from your bank's website. The account number is usually printed near the top, often next to your name and the account type (like "Checking" or "Savings").
Your debit card also carries your account number, though not always the full number. Look at the front of the card: the long number printed there is your card number, which is different from your account number. The account number is usually printed on the back of the card in smaller text, or you may need to call the bank to confirm which digits belong to your account versus your card.
If you have a checkbook, the account number is printed at the bottom left of every check, right after the routing number. The routing number comes first (usually nine digits), then your account number follows. This is often the easiest place to find it if you still have checks from your account.
Log into your online banking portal
Most banks display your account number in the account details section of their website or mobile app. Sign in with your username and password, then look for a tab labeled "Account Details," "Account Information," or "My Accounts." The account number should appear there alongside your balance and recent transactions.
If you cannot find it in the obvious place, try the settings or profile section. Some banks hide account numbers behind a security question or require you to click "Show Full Account Number" to display it. This is a security measure to prevent the number from being visible to someone looking over your shoulder.
Once you are logged in, you can also download or print a statement directly from the portal, which will show your account number. This gives you a permanent record you can save or print for your records.
Call your bank's customer service line
The fastest way to get your account number if you cannot locate it elsewhere is to call the number on the back of your debit card or the number listed on your bank's website. Have your identification ready — the bank will ask for your Social Security number, date of birth, or answers to security questions before they give you the account number over the phone.
Customer service representatives can also tell you which digits belong to your account number if you have a partial number and need clarification. They can confirm whether a number you found is correct or explain the difference between your account number and other numbers on your card or statements.
Most banks have customer service available during business hours and some offer 24/7 phone support. The wait time is usually short, and you will have your account number within minutes of calling.
Visit a branch in person
If you prefer to speak to someone face-to-face, walk into any branch of your bank during business hours with a photo ID. A teller can write down your account number for you or print a statement that shows it. This method works well if you have questions about which account number to use (for example, if you have multiple accounts at the same bank).
Bring your debit card or a recent statement with you so the teller can quickly locate your account. If you do not have either, the teller will ask for your name, address, and Social Security number to find your account in the system.
Request a new statement or account summary
If none of your current statements are available and you cannot access your online account, you can request a new statement or account summary from your bank. Most banks will mail this to you within a few business days, or you can ask them to email it if that option is available.
Some banks also offer account summaries through their mobile app that you can view or print immediately. This summary will include your account number along with your current balance and recent activity. Requesting a new statement is useful if your old statements have been lost or thrown away.

Frequently Asked Questions
Is my account number the same as my debit card number?
No. Your debit card number and account number are different. The card number is the 16-digit number printed on the front of your card. Your account number is shorter and appears on statements, checks, and sometimes on the back of your card. You need the account number for bank transfers and direct deposits.
What if I see multiple numbers on my statement?
Bank statements often show your routing number, account number, and check number all in one place. The routing number identifies your bank (usually nine digits). Your account number comes after it and is typically 10 to 12 digits. If you are unsure which is which, call your bank or check their website for a diagram showing where each number appears.
Can I use my account number to make purchases online?
No. Online purchases require your debit card number, expiration date, and CVV (the three-digit code on the back). Your account number is used for bank transfers, direct deposits, and ACH payments — not for card transactions. Never share your account number with a merchant unless they specifically ask for it for a bank transfer or automatic payment.
What should I do if I cannot remember my online banking password?
Most banks have a "Forgot Password" link on their login page. Click it and follow the steps to reset your password using your email address or phone number. You may also call customer service with your ID information, and they can help you regain access to your account without needing your account number first.
How long does it take to get my account number if I request a new statement?
Most banks mail new statements within three to five business days. If your bank offers email delivery or a digital account summary through their app, you can usually see your account number within minutes. Call your bank to ask which delivery method is fastest for your situation.
