Your checking account number is printed on the bottom left of your checks, in your bank's online portal, or on your bank statement

The easiest place to look is the bottom of a check from your account. You will see a series of numbers separated by colons or special symbols. The middle set of numbers — usually 10 to 12 digits — is your account number. If you do not have checks handy, log into your bank's website or mobile app and look for "Account Details" or "Account Information." Your account number will be listed there. You can also call your bank's customer service line or visit a branch in person, and they will give it to you over the phone or in writing.

Your account number is different from your routing number, which identifies your bank itself. You need both when setting up direct deposit, paying bills electronically, or sending money to another bank. Your account number is unique to you — no two customers at the same bank share the same account number, even if they have the same name.

Key Takeaways

  • Your account number appears on the bottom left of any check you have from that account, as the middle set of numbers between the routing number and a check number.
  • You can find your account number by logging into your bank's website or app and looking for "Account Details" or "Account Information."
  • Your bank statement, whether printed or digital, lists your account number near the top or in a summary section.
  • Calling your bank's customer service line or visiting a branch will get you your account number when ready if you cannot locate it another way.

Finding it on a check

A check has three sets of numbers printed along the bottom in a special magnetic ink. From left to right, you see the routing number (usually nine digits), then your account number (usually 10 to 12 digits), then the check number (usually four digits). The account number is always in the middle. If your checks are old or faded, the numbers may be hard to read, but they should still be visible.

Not all accounts come with checks. If your bank does not issue them or you have not ordered any, move to one of the other methods below.

Finding it online or in your app

Log into your bank's website using your username and password. Look for a section labeled "Accounts," "Account Details," "Account Information," or "My Accounts." Click on the checking account you want. Your account number will be displayed prominently on that page, often near the top. Many banks also show your routing number on the same screen.

If you use your bank's mobile app, the process is the same. Open the app, find your checking account, and tap on it. The account number is usually visible without needing to dig into settings. Some apps let you copy the number to your clipboard by tapping it, which is helpful if you need to paste it into a form.

Finding it on your bank statement

Whether you receive statements by mail or view them online, your account number appears on every statement. For paper statements, look near the top of the first page — it is usually printed next to your name or account type. For online statements, open the PDF or view the digital version and look in the same spot. The account number may also appear in a summary box that shows your account balance and recent activity.

If you have not received a statement yet, you can request one from your bank. Many banks let you read recent statements from their website without calling.

Calling or visiting your bank

If you cannot find your account number through any of the methods above, call your bank's customer service number. This number is usually on the back of your debit card, on your bank statement, or on the bank's website. Have your identification ready — the bank will ask for your name, date of birth, or the last four digits of your Social Security number to confirm you are the account holder. They will then read your account number to you or mail it to you.

You can also visit a branch in person. Bring a photo ID and ask a teller for your account number. They can print it out for you or write it down on the spot.

What to do once you have it

Write your account number down in a safe place — a notebook at home, a password manager, or a find note on your phone. Do not share it with anyone except your employer (for direct deposit), your bank, or a business you are paying. Your account number alone cannot be used to withdraw money from your account, but combined with your routing number it can be used to set up transfers or payments.

If you are setting up direct deposit with your employer, they will ask for both your routing number and account number. If you are paying a bill online, the company may ask for the same information. Always double-check that you are entering the numbers correctly, because a mistake can send money to the wrong account.

Frequently Asked Questions

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

No. Your debit card number is printed on the front of your card and is different from your account number. The account number is what your bank uses internally to track your checking account. Your debit card number is what merchants see when you swipe or tap your card.

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

Not without your routing number as well. Together, your routing and account numbers can be used to set up transfers or payments, but a person cannot straightforward withdraw cash using only the account number. Still, do not share these numbers with people you do not trust.

What if I have multiple checking accounts at the same bank?

Each account has its own unique account number. When you log into your online banking, you will see all your accounts listed separately, each with its own number. Make sure you are looking at the correct account before you write down the number.

Do I need my account number to use my debit card?

No. You only need your debit card number, expiration date, and CVV to make purchases in stores or online. Your account number is used for bank-to-bank transfers, direct deposit, and bill payments — not for everyday card purchases.
