Your account number appears on checks, online banking, and your bank statement
Your bank account number is printed on the bottom left of every check you write, right after the routing number. If you have checks, that is the fastest place to look. The number is usually 10 to 12 digits long, 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 shows on the account overview page, often labeled "Account Number" or "Account Details." You can also call your bank's customer service line — they will verify your identity and read it to you over the phone.
Your bank statement, whether you receive it by mail or email, also lists your account number at the top or in the account information section. If you have direct deposit set up through an employer or government program, the confirmation email or letter from that setup usually includes your account number as well.

Finding your account number online
Most banks display your account number prominently when you log into their website. Look for a section called "Accounts," "Account Summary," or "Dashboard." Your full account number should appear next to your account type — checking, savings, or money market.
Mobile banking apps work the same way. Open the app, tap the account you want, and the account number is usually visible on the first screen. Some banks hide the full number for security and show only the last four digits by default; tap or swipe to reveal the complete number.
If you cannot find it in the obvious places, look for a "Details" or "More Information" button. Some banks also send your account number in a separate secure message within your online banking portal if you request it.
Locating your account number on paper documents
Your checks are the most reliable paper source. Open your checkbook and look at the bottom of any check. You will see three sets of numbers: the routing number on the far left (usually nine digits), your account number in the middle (usually 10 to 12 digits), and the check number on the right. Write down only the account number.
Bank statements list your account number in the header or in a section labeled "Account Information." If you receive statements by mail, it is printed near your name and address. Digital statements show it in the same place — usually at the top of the first page or in a dedicated account details section.
Savings account books, if your bank still issues them, also print your account number on the cover or inside the front page. Loan documents and credit card statements from the same bank sometimes include your checking or savings account number, though not always.
Getting your account number by phone or in person
Call your bank's customer service number, which is on the back of your debit card or on your bank statement. Have your Social Security number, date of birth, and a form of identification ready. The representative will verify your identity and then read your account number to you.
Visit a branch in person with a photo ID. A teller can look up your account number in seconds and write it down for you. This is useful if you need the number immediately and do not have online access.
Some banks also send your account number via secure email or text message if you request it through your online banking portal. This leaves a record you can refer back to later.
What to do if you cannot locate your account number
If you have lost all your checks and cannot access online banking, call your bank. You do not need your account number to call — you only need to prove who you are. The bank will pull up your account using your name, address, and Social Security number.
If you have forgotten your online banking password, use the "Forgot Password" link on your bank's website to reset it. You will usually be asked to verify your identity using your email, phone number, or security questions. Once you regain access, your account number is visible immediately.
If your account has been closed, you can still request your old account number from the bank. This matters if you need it for tax records or to track a refund that was deposited to that account. The bank keeps records of closed accounts and can provide the number even years later.
Keeping your account number secure
Your account number is not as sensitive as your PIN or password, but it should still be treated carefully. Never share it in an email or text message, and do not post it on social media. If someone has your account number and routing number, they can set up unauthorized transfers or direct deposits.
When you give your account number to a legitimate business — your employer for direct deposit, a utility company for automatic payments, or a government agency for a refund — verify that you are dealing with the real organization. Scammers sometimes pose as banks or government offices to collect account numbers.
If you suspect someone has your account number without permission, contact your bank immediately. They can monitor your account for suspicious activity and issue you a new account number if needed.
Frequently Asked Questions
Is my account number the same as my debit card number?
No. Your debit card number is a 16-digit number printed on the front of your card. Your account number is separate and is usually 10 to 12 digits. Both connect to the same account, but they are different numbers used for different purposes.
Can I find my account number on a wire transfer receipt?
Yes. If you have sent or received a wire transfer, the confirmation receipt lists your account number. This is one of the few financial documents outside of checks and statements that includes it.
What if my bank uses letters in the account number?
Most banks use only numbers, but some smaller banks or credit unions may include letters. Write down exactly what appears — letters and numbers in the exact order — when you provide it to another organization.
Do I need my account number to set up direct deposit?
Yes. Your employer or the organization sending you money will ask for your account number along with your routing number. Both are required to deposit money into the correct account.
Can I change my account number?
Most banks will not change your account number while the account is active. If you are concerned about security, you can close the account and open a new one, which will have a different number. Contact your bank to discuss your options.
