Your checking account number is printed on the bottom left of your checks, in your bank's mobile app, and on statements your bank mails or emails you

The easiest place to look is the bottom of a check from your checkbook. You will see a series of numbers separated by vertical lines. The account number is the middle set of digits — usually 10 to 12 numbers long. If you do not have checks handy, open your bank's website or mobile app, log in, and look for your account details or account summary page. Your account number will be listed there. If you prefer paper, your monthly statement (whether mailed or emailed) also displays your account number near the top.

Your account number is different from your routing number, which identifies your specific bank branch. You need both when setting up direct deposit, paying bills online, or sending money to another person's account. The routing number appears to the left of your account number on a check.

Key Takeaways

  • Your account number appears on the bottom left of any check you have, in the middle set of numbers between two vertical lines.
  • You can find your account number by logging into your bank's website or mobile app and viewing your account details or summary.
  • Your monthly bank statement, whether mailed to your home or sent by email, displays your account number near the top of the page.
  • Your account number is not the same as your routing number — you need both for direct deposit and wire transfers.

Finding it in your bank's app or website

Log in to your bank's website or open the mobile app on your phone. Look for a section labeled "Account Details," "Account Information," "Account Summary," or sometimes just "Accounts." Your checking account number will be displayed prominently on that page, often near your account balance.

If you cannot find it, look for a menu button (usually three horizontal lines) or a settings icon. Some banks hide account details under a "View Account" or "Account Settings" option. You may also see a button to copy the number to your clipboard, which is helpful if you need to paste it somewhere else.

Finding it on a paper check

Look at the bottom of any check from your checkbook. You will see three groups of numbers separated by vertical lines. The first group (on the left) is your bank's routing number. The middle group is your account number. The third group (on the right) is the check number.

Your account number on a check is usually 10 to 12 digits long, though this varies by bank. If the numbers are hard to read because of printing quality or age, your bank can provide a clear copy by phone or through your online account.

Finding it on your bank statement

Your monthly statement — whether your bank mails it to your home or sends it by email — displays your account number near the top of the page. It usually appears next to your name and address, or in a section labeled "Account Information."

If you receive statements by email, search your email inbox for recent messages from your bank and open the most recent statement. If you receive paper statements and cannot find a recent one, you can request a copy from your bank by phone or through your online account.

What to do if you cannot locate it

Call your bank's customer service number, which is usually on the back of your debit card or on your bank's website. Have your identification ready — the bank will ask for your name, date of birth, and possibly the last four digits of your Social Security number to verify you are the account holder.

You can also visit a branch in person with a photo ID. A teller can write down your account number for you or print a statement showing it. This is often the fastest option if you need the number right away.

Why you need your account number

Your account number is required for direct deposit (when an employer or government agency deposits money into your account), setting up automatic bill payments, and sending money to someone else's account at the same bank or a different bank. You will also need it if you want to transfer money between your own accounts at different banks.

Keep your account number private, just as you would your debit card number. Do not share it in response to unsolicited phone calls or emails, even if the caller claims to be from your bank. Your bank will never ask for your account number over the phone unless you initiated the call.

The difference between account number and routing number

Your routing number identifies which bank or branch you use. Your account number identifies your specific account at that bank. You need both pieces of information to move money in or out of your account.

Think of it this way: the routing number is like the address of your bank building, and the account number is like your apartment number inside that building. On a check, the routing number comes first (on the left), and the account number comes second (in the middle).

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. Your account number is what you use for bank transfers and direct deposit. Your debit card number is what you use to make purchases or withdraw cash.

Can someone access my account if they know my account number?

Knowing only your account number is not enough to access your account or move money out of it. A person would also need your routing number, your PIN, or your online banking password. Still, do not share your account number with people you do not trust, and never share it in response to unsolicited calls or emails.

What if my account number is different on my check than on my statement?

This should not happen. If you notice a discrepancy, contact your bank right away. It may be a printing error on the check, or there may be a problem with your account. Your bank can clarify which number is correct.

Do I need my account number to use my debit card at a store?

No. You only need your debit card and your PIN to make purchases or withdraw cash at an ATM. Your account number is used for bank transfers, direct deposit, and bill payments — not for everyday card use.
