Check your checks or debit card first
Your bank account number is printed on the bottom left of every check you have. Look at the series of numbers between the routing number (on the left) and the check number (on the right). That middle set is your account number, usually 10 to 12 digits long.
If you do not have checks, your debit card statement or the back of your debit card itself may show the last four digits of your account number. This is not the full number, but it can help you confirm you are looking at the right account if you have multiple accounts at the same bank.
Key Takeaways
- Your account number appears on the bottom of every check, between the routing number and the check number.
- Your bank statement—whether paper or online—displays your full account number near the top or in the account details section.
- Your bank's website or mobile app shows your account number when you log in and view your account information.
- Calling your bank's customer service line or visiting a branch in person will give you your account number within minutes.
Look at your bank statement
Your account number is listed on every bank statement you receive. If you get paper statements in the mail, it usually appears near the top of the page, often labeled "Account Number" or "Acct #". The full number is printed there.
If you receive statements online, log into your bank's website, find your account details or statement section, and look for the account number field. Most banks display it prominently on the main account overview page. You can also download a PDF copy of any recent statement and search for the account number within the document.
Log into your online banking or mobile app
The fastest way to find your account number is to sign into your bank's website or mobile app. Once you are logged in, your account number is usually visible on the dashboard or account summary page without any extra steps.
Some banks hide the full number for security and show only the last four digits on the main screen. If that happens, look for a link or button labeled "Account Details," "View Full Account Number," or "Account Information." Clicking it will reveal the complete number. You may need to verify your identity again before the bank displays the full account number.
Call your bank or visit a branch
If you cannot find your account number online or on paper, call your bank's customer service number on the back of your debit card or on your most recent statement. Have your identification ready—a driver's license or Social Security number—and a representative will give you your account number over the phone.
You can also walk into any branch of your bank with a photo ID and ask a teller for your account number. They will look it up in seconds and write it down for you or print a statement showing it. This method works even if you have not visited that branch before.
What to do if you have multiple accounts
If you have more than one account at the same bank—such as a checking account and a savings account—each one has its own account number. When you log into online banking or call customer service, make sure you are looking at the correct account before you write down the number.
Your bank statement will clearly label which account it covers at the top. If you are using online banking, you can usually switch between accounts using a dropdown menu or account selector, and the account number will update to match the account you selected. Write down the account number for each account separately if you need them for different purposes.
Why you need your account number
Your account number is required for direct deposits, wire transfers, automatic bill payments, and setting up transfers between your accounts. It is also needed when you contact your bank about a specific transaction or account issue, because it tells the representative exactly which account you are asking about.
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. You often need both together to complete a transaction, such as when setting up payroll direct deposit or receiving a wire transfer from another person or organization.
Keep your account number secure
Your account number is sensitive information. Do not share it with anyone you do not trust, and do not post it on social media or in public forums. Scammers can use your account number along with your routing number to attempt unauthorized transfers or fraudulent transactions.
When you write down your account number, store it in a secure location such as a locked drawer, a safe, or a password manager. If you suspect someone has obtained your account number without permission, contact your bank immediately to report the potential fraud and discuss whether you need to close the account and open a new one.
Frequently Asked Questions
Is my account number the same as my card number?
No. Your debit or credit card number is different from your account number. The card number is printed on the front of the card; your account number is on the bottom of your checks or in your online banking. Some banks show the last four digits of your account number on your debit card, but the full card number and account number are separate.
Can I find my account number on my debit card?
Most debit cards do not print the full account number on the card itself for security reasons. Some banks print the last four digits. To get your full account number, check your checks, your bank statement, or log into online banking.
What if I lost my checks and do not have online banking?
Call your bank's customer service line using the number on the back of your debit card or from your last statement. A representative will verify your identity and give you your account number. You can also visit a branch in person with a photo ID.
Do I need to memorize my account number?
No. Write it down and keep it in a safe place, or save it in a password manager. You do not need to memorize it, but you should have it available when you need to set up direct deposit, wire transfers, or other transactions.
