Your checking account number is on the bottom left of your checks, in your bank's mobile app, or one call to your bank

The fastest way is to look at a check from your account. The account number appears at the bottom, usually 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 displayed on the account summary or dashboard page. If neither of those works, call your bank's customer service line (the number is on your debit card or bank statement) and give them your name and the last four digits of your Social Security number; they will read it to you.

You need this number when you set up direct deposit, arrange wire transfers, pay bills through your bank's bill pay system, or give it to an employer or government agency. The account number is unique to your specific account at that bank, even if you have multiple accounts there.

Key Takeaways

  • Your checking account number appears at the bottom left of any check you have, after the routing number.
  • You can find it instantly by logging into your bank's website or mobile app and looking at your account summary.
  • Your bank's customer service team can read it to you over the phone if you provide your name and last four digits of your Social Security number.
  • The account number is different from your routing number and is unique to this specific account only.

Reading the number from a check

Open a checkbook from your account. At the bottom of the check, you will see a series of numbers printed in a special magnetic ink format. The first set of numbers (usually nine digits) is your routing number. Immediately after that comes your account number, which is typically between eight and twelve digits long. The last set of numbers on the right is the check number.

Write down the account number exactly as it appears. Do not include the routing number or check number. If the numbers are hard to read because the check is old or worn, use one of the other methods instead — a bank employee can confirm you have copied it correctly.

Finding it in your bank's app or website

Log into your bank's mobile app or website using your username and password. Look for a section labeled "Account Summary," "My Accounts," "Account Details," or "Account Information" — the exact name varies by bank. Your account number is usually displayed prominently on this page, often near your account balance.

Some banks also show it when you click on the specific checking account tile or card. If you cannot find it on the main page, look for a link that says "View Account Details" or "Account Settings." The account number will be listed there. You can usually copy it directly from the screen or take a screenshot for your records.

Calling your bank directly

Find the customer service number on the back of your debit card, on a recent bank statement, or on your bank's website. Call during business hours and tell the representative you need your checking account number. They will ask you to verify your identity — typically your full name and the last four digits of your Social Security number, though some banks may ask for your date of birth or mother's maiden name.

Once verified, the representative will read your account number to you. Ask them to spell it out or repeat it so you can write it down correctly. This method works even if you have lost your checks and cannot access your online account.

What to do if you cannot find it

If you do not have checks, cannot log into your account, and cannot reach your bank by phone, visit a branch in person. Bring a photo ID and ask a teller for your account number. They can look it up in seconds using your name and ID.

If you have recently opened the account and have not received checks yet, your bank may have sent the account number in a welcome email or letter. Check your email inbox and spam folder for messages from your bank. The account number is often included in the subject line or in the body of the email.

Keeping your account number safe

Your account number is not as sensitive as your PIN or password, but it should still be treated with care. Do not share it with people you do not trust. Legitimate businesses — your employer, the IRS, your mortgage lender — will ask for it directly and will not ask you to confirm it through email or text.

If you suspect someone has your account number and may misuse it, contact your bank immediately. They can monitor the account for unauthorized activity and issue you a new account number if necessary, though this is rare.

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 your bank uses internally to identify your checking account. You need the account number for direct deposit and wire transfers, not the debit card number.

Can I use my account number to make purchases online?

No. Online purchases require your debit card number, expiration date, and CVV. Your account number is for bank-to-bank transfers and direct deposit only. Never enter your account number into a retail website or payment form.

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

Each account has its own unique account number. When you log into your bank's app, you will see all your accounts listed separately, each with its own number. Make sure you are copying the number from the correct account before you use it.

Do I need my account number to transfer money between my own accounts?

Usually not. Most banks let you transfer between your own accounts using just the account names or a dropdown menu in their app. You may need the account number if you are setting up a transfer through a third-party service or if your bank specifically asks for it.
