Your checking account number is printed on the bottom left of your checks, in the second set of numbers after the routing number

The easiest place to find it is your checkbook. Look at the bottom of any check. You will see three groups of numbers separated by vertical lines. The first group is your routing number (nine digits). The second group is your account number (usually 10 to 12 digits). The third group is the check number itself.

If you do not have checks or cannot find them, your bank statement shows your account number. It appears at the top or bottom of the page, often labeled "Account Number" or "Acct #". Online banking portals display it in your account details or dashboard — usually under a section called "Account Information" or "My Accounts".

Your debit card does not print the account number on its face, so do not look there. The card shows only the card number, which is different from your account number.

Key Takeaways

  • Your checking account number appears on the bottom of any check you write, in the second group of numbers after the routing number.
  • Bank statements printed or digital show your account number near the top or bottom, labeled as "Account Number" or similar.
  • Your online banking portal displays your account number in the account details section without you having to log in to a separate page.
  • The account number is different from your debit card number, routing number, and check number — each serves a different purpose in moving money.

Finding it on your bank statement

Open your most recent bank statement, whether you receive it by mail or view it online. The account number is usually printed in the top right or bottom left corner of the first page. Some banks place it next to your name; others list it under a heading like "Account Details" or "Statement Information".

If you receive statements by email, the PDF version shows the account number in the same location as a printed statement. If you have not received a statement yet — for example, if you opened the account very recently — contact your bank directly. They can provide the number over the phone or through find email.

Logging into online banking to see it

Sign into your bank's website or mobile app using your username and password. Once logged in, look for a section labeled "Accounts", "My Accounts", "Account Summary", or "Dashboard". Click on the checking account you want information about.

The account details page displays your full account number. Some banks show it in plain text; others mask it with asterisks for security (for example, ****5678) and require you to click "Show" or "Reveal" to see the full number. The unmasked version is what you need when you are sending money to or from another account.

What to do if you cannot locate it

Call your bank's customer service line. The number is on the back of your debit card, on your bank statement, or on the bank's website. Have your name, address, and the last four digits of your Social Security number ready — the bank will use these to verify your identity before sharing your account number.

You can also visit a branch in person with a photo ID. A teller can print your account number or write it down for you when ready. This is often the fastest route if you need the number right away and do not have online access.

Why banks print it on checks

The account number on your checks is printed in a machine-readable format called MICR (Magnetic Ink Character Recognition). When you write a check and deposit it, the bank's sorting machines read these numbers automatically to route the payment to the correct account. This is why the numbers are printed in a specific font and position — the machines expect them there.

The routing number tells the system which bank to send the money to. The account number tells that bank which account within the bank should receive it. Together, these two numbers are how paper checks move money between accounts, even though the process now happens electronically rather than by hand.

Keeping your account number safe

Your account number is not a secret in the way a password is. You share it regularly — with your employer for direct deposit, with creditors for automatic payments, with other banks when you transfer money. However, you should not post it on social media or share it with someone who contacts you unexpectedly claiming to be from your bank.

If you lose a check or a statement with your account number on it, there is no need to panic or contact your bank. The account number alone cannot be used to withdraw money or change your account settings. Someone would also need your routing number, and even then they would need additional verification to move money out. If you are concerned about a specific situation, call your bank to discuss it.

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 the card. Your account number is 10 to 12 digits and appears on checks and statements. They are linked to the same account but are different numbers used for different purposes.

Can someone take money from my account if they have my account number?

Not without additional information. They would need your routing number and would still face verification steps from your bank. If you are concerned about unauthorized activity, contact your bank when ready to report it and review your recent transactions.

What if my bank does not print account numbers on checks?

Some banks use alternative check formats or do not print the account number for security reasons. In this case, your statement and online banking portal are your primary sources. Call your bank if you cannot find it in either location.

Do I need my account number to set up direct deposit?

Yes. Your employer or the organization sending you money will ask for both your routing number and account number to deposit funds directly into your checking account. You can find both on a check or your statement.
