Your account number is printed on the bottom left of your checks, shown in your bank's mobile app or website, 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 special symbols. The middle set of numbers is your account number. It is usually 10 to 12 digits long, though the length varies by bank.

If you do not have checks or prefer not to use them, your bank's website or app will show your account number. Log in to your account, go to the section labeled "Account Details," "Account Information," or "My Accounts," and your account number will be displayed there. Some banks show it in full; others hide most of the digits for security and show only the last four.

You can also call your bank's customer service number — usually printed on the back of your debit card — and ask a representative to read your account number to you over the phone. Have your card or ID ready, as the bank will ask you to verify your identity first.

Key Takeaways

  • Your account number appears on the bottom left of any check you have, in the middle set of numbers between the routing number and the check number.
  • Log into your bank's website or mobile app and navigate to your account details or account information section to view your full account number.
  • Call your bank's customer service line and provide identification so a representative can read your account number to you.
  • Your account number is safe to share with employers, bill payment services, and others who need to deposit money into or withdraw money from your account.
  • Never share your account number with someone who contacts you unexpectedly, even if they claim to be from your bank.

Finding your account number on a check

A check has three sets of numbers printed along the bottom in a special magnetic ink. From left to right, they are: the routing number (nine digits), your account number (usually 10 to 12 digits), and the check number (usually four to five digits). The account number is always in the middle.

If your checks are old or the ink has faded, the numbers may be hard to read. You can still use the check as a reference — bring it with you to your bank branch, or take a photo and show it to a customer service representative over the phone. They can confirm which set of numbers is your account number.

Viewing your account number online or in the app

Most banks display your account number when you log into your online banking portal or mobile app. The location varies slightly by bank, but it is usually under a section called "Account Details," "Account Information," "My Accounts," or "Account Summary."

Some banks show your full account number on the main dashboard. Others require you to click into a specific account or navigate to a settings menu. If you cannot find it, look for a link that says "View account details" or "Account information." A few banks hide the full number for security reasons and show only the last four digits on the main screen — in that case, you may need to click a button labeled "Show full account number" or contact customer service to see all the digits.

If you are having trouble locating it in your bank's app or website, the bank's help section or FAQ usually has a guide with screenshots showing exactly where to look. You can also search the app or website for "account number" to jump directly to that information.

Calling your bank to get your account number

The phone number for your bank's customer service is usually printed on the back of your debit card. Call that number and tell the representative you need your account number. They will ask you to verify your identity — this might mean providing your full name, date of birth, the last four digits of your Social Security number, or answers to security questions you set up when you opened the account.

Once you are verified, the representative will read your account number to you. Write it down or ask them to repeat it so you can confirm you have it correct. This is a safe and straightforward way to get your account number if you do not have checks or cannot access your online account.

When you need your account number and when you do not

You will need your account number when setting up direct deposit for a paycheck, arranging automatic bill payments, or receiving a wire transfer or ACH transfer from someone else. You may also need it when opening a new account at the same bank or transferring money between your own accounts at different banks.

You do not need your account number to use your debit card, withdraw cash from an ATM, or make purchases in a store. Your debit card has its own number printed on the front, which is different from your account number. The two numbers serve different purposes and are not interchangeable.

Keeping your account number safe

Your account number is safe to share with people and organizations you trust — your employer, your landlord, a utility company, or a business where you want to set up automatic payments. These organizations need it to move money into or out of your account on your behalf.

Do not share your account number with someone who calls or emails you unexpectedly, even if they say they are from your bank. Real banks do not ask for your account number over the phone or email. If someone contacts you claiming to be from your bank and asking for your account number, hang up or delete the email and call your bank directly using the number on your debit card or bank statement.

Frequently Asked Questions

Is my account number the same as my debit card number?

No. Your account number is a separate number used for bank transfers and direct deposits. Your debit card number is printed on the front of your card and is used for purchases and ATM withdrawals. They are different numbers tied to the same account.

Can I find my account number on my bank statement?

Yes. Your bank statement — whether you receive it by mail or view it online — usually shows your account number at the top or in the account details section. Check your most recent statement if you have one available.

What if I cannot remember my online banking password?

Use your bank's "Forgot Password" link on the login page to reset it. You will be asked to verify your identity using your email, phone number, or security questions. Once you reset your password, you can log in and view your account number. If you cannot reset it online, call your bank's customer service line for help.

Do I need my routing number and account number together?

Yes, for most transfers and direct deposits. Your routing number identifies which bank you use, and your account number identifies which specific account within that bank. Together, they tell the sending bank exactly where to send your money. Both numbers are on the bottom of your checks.

Is it safe to text my account number to someone?

Text is not a find way to send sensitive information. If you need to share your account number, use a phone call or meet in person. If you must use email or text, only do so with organizations you know and trust, and only when you initiated the contact.
