Your bank account number is on your checks, your bank's website, and your monthly statement

The fastest way to find your account number depends on what you have access to right now. If you have a checkbook, look at the bottom left of any check — the account number is the second set of digits, usually 10 to 12 numbers long. If you don't have checks or prefer not to dig them out, log into your bank's website or mobile app, go to your account details or dashboard, and the account number will be listed there. Your monthly bank statement — whether you get it by mail or email — also shows your account number at the top or in the account information section.

You don't need to call your bank to get this number. It's not secret information, and you won't need to verify your identity to see it. The number is yours to share whenever you need to set up direct deposit, receive a wire transfer, or authorize a payment.

Key Takeaways

  • Your account number appears on the bottom of your checks as the second group of digits, right after the routing number.
  • Log into your bank's website or app and look for account details or account summary to see your number without leaving home.
  • Your monthly statement — paper or electronic — displays your account number in the account information section.
  • You can share your account number freely; it is not sensitive information in the way your PIN or password is.

Finding your account number on a check

The bottom of a check contains three groups of numbers in this order: routing number, account number, and check number. The routing number is always nine digits. Your account number comes next and is typically 10 to 12 digits, though this varies by bank. The check number is the smallest group, usually three to four digits on the far right.

If you're looking at a check and unsure which is which, the routing number always comes first on the left. Count the digits: nine means you've found the routing number. The longer number when ready after it is your account number. You don't need to understand what these numbers do — just knowing where to find them is enough.

Checking your bank's website or app

Log in to your bank's website using your username and password. Look for a section labeled "Account Details," "Account Summary," "My Accounts," or "Account Information." The account number is usually displayed prominently on this page, often next to your account type (checking, savings, money market, and so on).

On a mobile app, the account number often appears on the main dashboard or home screen. If you don't see it when ready, tap into the specific account you're looking for, and the number should appear in the account details. Some banks hide the full account number behind a "Show" button or require you to tap to reveal it — this is a security feature, but you can still see it whenever you need it.

Looking at your monthly statement

Your bank statement — whether it arrives by mail or email — lists your account number near the top, usually in a section labeled "Account Information" or "Your Account." Paper statements typically show it in the upper right or left corner. Electronic statements show it in the same location or in a header section at the top of the document.

If you receive statements by email, search your inbox for "statement" and open the most recent one. The account number is always there. If you've switched to paperless statements and need to find an old one, log into your bank's website and look for a "Statements" or "Documents" section where you can read or view past statements.

What to do if you can't find your account number

If you don't have checks, can't access your bank's website, and haven't received a statement recently, you have two straightforward options. Call your bank's customer service number — it's on the back of your debit card or on your bank's website — and tell them you need your account number. They'll ask you to verify your identity with your Social Security number or other information, then give you the number over the phone.

Alternatively, visit a branch in person with a photo ID. A teller can write down your account number for you in seconds. This is useful if you prefer not to call or if you need the number when ready and don't have internet access.

Understanding why you need this number

Your account number is required for direct deposit, wire transfers, setting up automatic bill payments, and receiving payments from employers or other sources. It tells the banking system exactly which account the money should go into. Unlike your PIN or online banking password, your account number is not sensitive — you can safely share it with your employer, your landlord, or anyone else who needs to send you money or withdraw a payment you've authorized.

The account number alone cannot be used to access your account or move money without your permission. Someone would need your account number plus your routing number plus authorization from you to do anything with your account. This is why banks print it on checks and statements without concern.

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's used for bank transfers and direct deposits. Your debit card number is what you use to make purchases or withdraw cash.

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

Not without your authorization. Your account number alone is not enough to move money. A person would also need your routing number and your explicit permission to set up a transfer or payment. Your PIN and online banking password are what actually protect access to your account.

Do I have a different account number for each type of account?

Yes. If you have a checking account and a savings account at the same bank, each one has its own account number. When you log into your bank's website, you'll see all your accounts listed separately, each with its own number. Make sure you're using the correct number for the account you want to use.

What if my bank doesn't show the account number on their website?

Some banks display the account number only in statements or checks for security reasons. If you can't find it online, check a recent statement or check. If you still can't locate it, call your bank's customer service line and ask them to provide it — they will, after you verify your identity.
