Your account number is printed on the bottom left of your checks, in your bank's mobile app, and on paper statements mailed to you
The easiest place to look is the bottom of a check from your checking account. The account number appears after the routing number, separated by a colon or space. If you do not have checks, open your bank's mobile app or website, log in, and look for "Account Details" or "Account Information" — most banks show the full number there. You can also call your bank's customer service line, give them your name and identifying information, and they will read it to you over the phone.
Paper statements mailed monthly also list your account number near the top, usually next to your name and address. If you have switched to paperless statements, you can still access old statements through your online banking portal and find the number there.
Key Takeaways
- Your account number appears on the bottom left of checks, right after the routing number.
- Your bank's website or mobile app shows your account number under Account Details or Account Information.
- Monthly paper statements print your account number near the top of the page.
- Your bank's customer service team can tell you your account number over the phone if you provide your name and identifying information.
- The account number is different from your routing number and is unique to your specific account at that bank.
Finding it in your online banking portal
Log into your bank's website or app and look for a section labeled "Accounts," "My Accounts," or "Account Summary." Click on the checking or savings account you need the number for. The account number is usually displayed prominently on that page, often near your account balance.
Some banks hide the full number behind a "Show" button or require you to click on the account to see all digits. If you see only the last four digits, look for a link that says "View Full Account Number" or similar. You may need to answer a security question or verify your identity before the full number appears.
Reading it from a check
Look at the bottom of any check. You will see three sets of numbers separated by colons or spaces. The first set is your routing number (nine digits). The second set, in the middle, is your account number. The third set is the check number.
Account numbers vary in length — some banks use nine digits, others use ten or more. Write down all the digits you see in the middle section. If you are missing a check or do not have any, do not worry; the other methods above will work just as well.
Calling your bank directly
Pick up the phone and call the customer service number on the back of your debit card or on your bank's website. Tell the representative you need your account number. They will ask you to verify your identity — usually your full name, date of birth, and the last four digits of your Social Security number or a PIN you set up.
Once verified, they will read your account number to you. Write it down carefully, digit by digit, and ask them to repeat it so you can confirm you have it right. This method works even if you have lost your checks or do not use online banking.
What to do if you cannot find it
If you have tried the methods above and still cannot locate your account number, contact your bank by phone or visit a branch in person. Bring a government-issued ID so the teller can verify who you are. They can print your account number for you or write it down on a piece of paper.
Do not share your account number with anyone you do not trust. Scammers sometimes pose as bank employees to trick people into revealing this information. Your bank will never ask for your account number via email or text — they already have it on file.
Why you need it and when to use it
Your account number is required when you set up direct deposit for paychecks, tax refunds, or government payments. It is also needed when you give someone permission to withdraw money from your account, such as for automatic bill payments or loan payments. Insurance companies, employers, and government agencies all ask for this number to send refunds or payments directly to your bank.
Keep your account number in a safe place, but do not memorize it or write it on something you might lose. If you are worried about security, you can always call your bank to confirm the number rather than relying on a written copy.
Frequently Asked Questions
Is my account number the same as my routing number?
No. Your routing number identifies your bank (nine digits), while your account number identifies your specific account at that bank. Both appear on the bottom of checks, with the routing number first and the account number second. You need both numbers to set up direct deposit or automatic payments.
Can someone steal money from my account if they have my account number?
Your account number alone is not enough to steal money. A person would also need your routing number and usually your name. Even then, most banks require additional verification before processing transfers. However, do not share your account number with people you do not trust, and never give it out in response to an unsolicited email or call.
What if I have multiple accounts at the same bank?
Each account has its own unique account number. If you have a checking account and a savings account, they will have different numbers. When you set up direct deposit or payments, make sure you use the correct account number for the account you want the money to go into.
Do I need my account number to check my balance?
No. You can check your balance by logging into your online banking portal with your username and password, calling your bank's automated phone line, or visiting an ATM. Your account number is mainly needed when you are sending or receiving money, not for viewing your balance.
