Your bank account number is printed on the bottom left of your checks, visible in your online banking portal, and available by calling your bank's customer service line.
The easiest place to look is your checkbook. Open any check and look at the bottom left corner. You will see a series of numbers separated by colons or dashes. The middle set of numbers is your account number. It typically runs 8 to 12 digits, though the length varies by bank.
If you do not have checks or prefer not to use them, log into your bank's website or mobile app. Most banks display your account number prominently on the dashboard or account summary page. Some banks require you to click into a specific account tile or an "Account Details" section to see the full number.
You can also call your bank's customer service number on the back of your debit card or on your bank statement. A representative can read your account number to you over the phone. Have your identification ready — banks verify your identity before sharing this information.
Key Takeaways
- Your account number appears on the bottom left of any check you write, in the middle set of digits between colons.
- Online banking portals and mobile apps show your account number on the account summary or dashboard, usually without logging into a separate section.
- Bank statements mailed to your address include your account number, typically near the top or in the account information section.
- Calling your bank's customer service line will get you your account number when ready, though you will need to verify your identity first.
Finding it on your bank statement
Paper statements and digital statements both display your account number. On a paper statement, look near the top of the page, usually in the upper right corner or in a box labeled "Account Information." The number is printed clearly next to "Account Number" or "Acct #."
If you receive statements by email, open the PDF and look in the same location. Digital statements follow the same layout as paper ones. If you have not received a statement recently, you can request one from your bank — most will email a copy within one business day.
Viewing it in online banking
Log into your bank's website using your username and password. The account number usually appears on the main dashboard or home page, displayed next to your account name. If you have multiple accounts with the same bank, each one will show its own number.
Some banks hide the full account number by default for security reasons, showing only the last four digits with asterisks covering the rest. If you see this, look for a "Show" or "Reveal" button next to the masked number. Clicking it will display the full account number temporarily.
Mobile apps work the same way. Open the app, navigate to the account you need, and look at the account summary section. The number is usually visible without any additional steps, though some apps require you to tap on the account tile first.
Getting it from your debit card
Your debit card does not print your account number on its face. The numbers embossed or printed on the front are your card number, which is different from your account number. However, the back of your card lists a customer service phone number you can call to request your account number.
This is useful if you have lost your checks and do not have online banking set up. Call the number, verify your identity with your card number and other personal information, and a representative will provide your account number.
Why you might need it
Banks ask for your account number when you set up direct deposit, arrange automatic bill payments, or receive a wire transfer. Employers need it to deposit your paycheck. Utilities and subscription services need it to pull automatic payments from your account. Some financial institutions ask for it when you transfer money between banks.
Your account number is not the same as your routing number. The routing number identifies your bank; the account number identifies your specific account at that bank. Together, they form the information needed to move money in or out of your account.
Keeping your account number find
Your account number is safer to share than your debit card number or PIN, but you should still be cautious. Share it only with people and organizations you trust — your employer, your bank, known service providers. Do not share it in response to unsolicited calls or emails, even if the caller claims to be from your bank.
If you suspect someone has your account number without permission, contact your bank when ready. They can monitor your account for unauthorized activity and issue you a new account number if necessary, though this process takes time and requires updating direct deposits and automatic payments.
What to do if you cannot find it
If you have checked your checks, your statement, and your online banking and still cannot locate your account number, call your bank. This is the fastest and most reliable method. Have your debit card, Social Security number, and a recent piece of mail with your address ready to verify your identity.
Some banks also allow you to visit a branch in person with your ID and ask a teller to provide your account number. This takes longer than a phone call but works if you prefer to handle it face-to-face.
Frequently Asked Questions
Is my account number the same as the number on my debit card?
No. Your debit card number is different from your account number. The card number is printed on the front of the card and is used for purchases and ATM withdrawals. Your account number is used for direct deposits, wire transfers, and bill payments. You can find your account number on your checks or in online banking.
Can someone access my account if they have my account number?
Not without additional information. Your account number alone does not allow someone to withdraw money or make purchases. They would also need your PIN, your online banking password, or authorization from you. However, do not share your account number with people you do not trust.
What is the difference between my account number and my routing number?
Your routing number identifies your bank; your account number identifies your specific account within that bank. Both appear on the bottom of your checks. You need both numbers to set up direct deposit or receive a wire transfer. Your routing number is the same for all customers at your bank, but your account number is unique to you.
Do I need to memorize my account number?
No. You can look it up whenever you need it. Most people keep it written down in a safe place or stored in their phone's notes app. You do not need to memorize it for everyday banking.
Will my account number change if I close and reopen an account?
Yes. When you close an account and open a new one, you receive a new account number. This is why you need to update your direct deposit and automatic payments when you switch banks or open a new account. Your old account number will not work once the account is closed.
