Your checking account number is printed on the bottom left of your checks, in your bank's online portal, and on statements mailed to you

The easiest place to look is the bottom of any check you have. The account number appears after the routing number and before the check number. If you do not have checks handy, log into your bank's website or mobile app — your account number is usually visible on the account summary page or under account details. You can also call your bank's customer service line and they will read it to you over the phone.

Your account number is typically 8 to 12 digits long, though the length varies by bank. It is unique to your specific account at that bank, so if you have multiple checking accounts, each one has its own number. You will need this number when setting up direct deposit, making wire transfers, or authorizing automatic payments.

Key Takeaways

  • Your checking account number appears on the bottom left of your checks, right after the routing number.
  • You can find it by logging into your bank's website or app and looking at your account summary or details page.
  • Calling your bank's customer service number will get you the account number read aloud if you cannot locate it in writing.
  • The account number is usually 8 to 12 digits and is different for each account you hold at the same bank.

Finding it on a paper check

Look at the bottom of any check. You will see three groups of numbers printed in a special magnetic ink. The first group is the routing number (9 digits), the second is your account number (usually 8 to 12 digits), and the third is the check number (usually 3 to 4 digits). The account number sits in the middle of these three.

If your checks are old or the print is faded, the numbers may be hard to read. In that case, move to one of the other methods below rather than guessing. Using the wrong account number can send money to the wrong place or cause a transaction to fail.

Finding it in your online banking portal

Log into your bank's website or mobile app using your username and password. Once you are signed in, look for a page labeled "Accounts," "Account Summary," "Account Details," or "My Accounts." Your checking account number is usually displayed prominently on this page, often near your account balance.

Some banks also show the account number in a section labeled "Account Information" or "Account Settings." If you cannot find it in the main view, look for a dropdown menu or a link that says "View Account Details" or "Account Number." The account number is not sensitive information in the way a password is, so banks display it openly in their portals.

Finding it on a bank statement

Open a recent statement from your bank — either a paper statement mailed to you or a PDF you downloaded from your online portal. The account number is typically printed near the top of the statement, often next to your name or account type. It may also appear in a section labeled "Account Information" or "Statement Details."

If you receive paper statements, you do not need to wait for the next one to arrive. Log into your online portal and read a recent statement as a PDF. The account number will be in the same location on the digital version.

Calling your bank to get the number

Find the customer service phone number on the back of your debit card, on your bank statement, or on your bank's website. Call and tell the representative you need your checking account number. They will ask you to verify your identity — usually by providing your Social Security number, date of birth, or answers to security questions you set up when you opened the account.

Once verified, the representative will read your account number to you. Write it down as they say it, and ask them to repeat it so you can confirm you have it correct. This method takes a few minutes but is reliable if you cannot access your checks or online portal.

What to do if you cannot find it

If you have lost access to your online banking, do not have checks, and cannot reach customer service by phone, visit a branch in person. Bring a government-issued ID and ask a teller for your account number. They will verify your identity and provide it when ready.

Do not share your account number with anyone who contacts you unsolicited — by phone, email, or text. Legitimate businesses and government agencies will not ask you to confirm your account number this way. If someone claims to be from your bank and asks for it, hang up and call your bank directly using the number on your debit card or statement.

Why you need it and where you will use it

Your account number is required for several common banking tasks. Direct deposit from an employer or government benefit program needs both your routing number and account number. Wire transfers, automatic bill payments, and ACH transfers (moving money between banks) all require your account number. Some employers and service providers also ask for it when setting up payroll deductions or subscription payments.

You may also need it when disputing a transaction with your bank, setting up a new account at a different bank, or providing proof of your account to a third party. Unlike your PIN or online banking password, your account number is not secret — it is printed on every check you write — so sharing it for legitimate purposes is safe.

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 the card and is different from your account number. The account number is what the bank uses internally to identify your checking account. You need the account number for direct deposit and transfers, not for card purchases.

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 portal, you will see all your accounts listed separately, each with its own number. Make sure you are using the correct account number for the transaction you are making.

Can someone steal money from my account if they know the account number?

Knowing only the account number is not enough to transfer money out. A thief would also need your routing number and typically your name and address. Even then, most banks require additional verification before processing transfers. If you are concerned about unauthorized activity, contact your bank when ready.

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

Yes. Your employer or the organization sending the deposit needs both numbers. The routing number tells the system which bank to send the money to, and the account number tells the bank which specific account within that bank should receive it.
