Your checking account number is the unique identifier your bank assigns to that specific account

Your checking account number is a string of digits—usually 8 to 12 numbers, though this varies by bank—that identifies your individual account within your bank's system. It is different from your routing number, which identifies the bank itself. You need both pieces of information to receive direct deposits, set up automatic bill payments, or give someone your banking details for a wire transfer.

Your account number appears on multiple documents and in multiple places, so you have several ways to find it without calling the bank or visiting a branch.

Key Takeaways

  • Your checking account number is printed on the bottom left of every check you write, before the routing number.
  • Your bank statement—whether you receive it by mail or view it online—displays your account number on the first page.
  • Your debit card does not show your account number, but your bank's website or mobile app will display it under account details.
  • If you have lost access to all these sources, you can call your bank's customer service line and verify your identity to get the number read to you.

Check the bottom of your checks

The easiest place to find your account number is at the bottom of any check from your checking account. The numbers printed along the bottom edge follow a standard format: the first set of numbers is your routing number, and the second set is your account number. The account number typically comes after a space or colon.

If you have a checkbook, pull out any check and look at the bottom left corner. The account number is usually 8 to 12 digits long. This method works even if you have not written a check in months—the number does not change unless you close the account and open a new one.

Look at your bank statement

Your account number appears on the first page of every bank statement, usually in the upper right corner or near the account summary section. This works whether you receive statements by mail or view them online through your bank's website.

If you bank online, log into your account and navigate to the statements or account information section. Most banks display your full account number there. If you receive paper statements, the number is printed near the top of the first page, often labeled "Account Number" or "Account #."

Use your bank's website or mobile app

Log into your bank's online banking portal or open the mobile app and look for an "Account Details," "Account Information," or "My Accounts" section. Your checking account number will be displayed there alongside your account type and current balance.

The exact location varies by bank. Some banks show it on the main dashboard; others require you to click into the specific account. If you cannot find it, most banks have a search function—type "account number" into the help section and it will direct you to the right page.

Call your bank if you cannot locate it

If you do not have access to checks, statements, or online banking, call the customer service number on the back of your debit card or on your bank's website. Have your identification ready—the bank will ask you to verify your identity before reading your account number over the phone.

This is a standard request and takes less than five minutes. The bank will confirm your name, address, and possibly the last four digits of your Social Security number before providing the full account number.

What your account number is used for

You will need your account number when you set up direct deposit for paychecks or benefits, arrange automatic bill payments, or ask someone to send you a wire transfer or ACH payment. You may also need it to link your checking account to a savings account at the same bank or to a third-party service like a payment app.

Your account number is safe to share with people who need to send you money or deposit funds into your account. It is not the same as your PIN or password, and sharing it does not give someone access to withdraw money. However, do not share it with anyone you do not trust, and never give it out in response to an unsolicited phone call or email.

The difference between account number and routing number

Your routing number identifies your bank or credit union. Your account number identifies your specific account within that bank. You need both to complete most banking transactions. The routing number is the same for all customers at your bank (or all customers at a specific branch, depending on the bank). Your account number is unique to you.

When you write a check, both numbers are printed at the bottom. When you set up direct deposit, you will enter both. If you give someone only your account number without the routing number, they will not be able to deposit money into your account.

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 a separate set of digits that appears on your checks and statements. They are linked to the same account, but they are not the same number.

Can someone withdraw money if they have my account number?

No. Your account number alone does not give someone the ability to withdraw money. They would also need your routing number, PIN, or online banking password. Sharing your account number with someone who needs to deposit money into your account is safe.

What if my account number changed?

Your account number changes only if you close your checking account and open a new one. If you have recently opened a new account at the same bank, you will have a different account number. Check your most recent statement or online banking to confirm which number belongs to your current account.

Do I need both my account number and routing number for direct deposit?

Yes. Your employer or the organization sending you the deposit will ask for both your routing number and your account number. Without both, the deposit cannot be processed to the correct account.
