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

The fastest place to look is the bottom of a check you have written. The account number appears after the routing number and before the check number, printed in magnetic ink. If you do not have a checkbook, log into your bank's website or mobile app — your account number will be listed on the dashboard, usually near your account name or balance. Paper statements mailed by your bank also show the account number at the top or in a summary section.

If you cannot find it through those routes, call the customer service number on the back of your debit card or on your most recent statement. A representative can read it to you over the phone in under a minute. Some banks also display it in the account settings or profile section of their app.

Key Takeaways

  • Your account number is on the bottom left of any check you have written, after the routing number.
  • Log into your bank's website or app to find it on your account dashboard or in account settings.
  • Paper bank statements show your account number at the top or in a summary section.
  • Call your bank's customer service line if you cannot locate it through these methods.
  • Never share your account number with anyone who contacts you unsolicited.

Finding it in your online banking portal

Most banks display your account number prominently when you log in. Look for a section labeled "Account Details," "Account Information," or "My Accounts." The number will be listed alongside your account type (checking, savings, money market) and current balance.

If you cannot find it on the main dashboard, check the account settings or profile area. Some banks require you to click on a specific account to see its full number. Mobile apps often show a shortened version by default — tap the account name or an info icon to reveal the complete number.

Reading it from a check

The bottom of a check contains three numbers printed in magnetic ink. From left to right, they are: routing number (nine digits), account number (typically 10 to 12 digits), and check number. Your account number is always the middle set of digits.

If you have not written checks in years, an old check still works — your account number does not change unless you close and reopen the account. Even a check from five years ago will show the correct number.

Locating it on paper statements

Bank statements mailed to your address show your account number in one of two places: at the very top of the first page, often next to your name and address, or in a summary box that lists account details. The number may be printed in full or with some digits masked for security.

If your statement shows a masked number (like the last four digits only), call your bank to request the full account number. They will verify your identity and provide it immediately.

What to do if you cannot locate it

Call the customer service number printed on the back of your debit card or on any bank statement. Have your Social Security number and a form of identification ready. The representative will verify your identity and read your account number to you.

You can also visit a branch in person with a photo ID. A teller can print your account number or write it down for you on the spot. This is often the fastest option if a branch is nearby.

Keeping your account number secure

Your account number is sensitive information. Do not share it with anyone who calls or emails you unsolicited, even if they claim to be from your bank. Your bank will never ask for your account number over the phone or email — they already have it on file.

When you provide your account number to set up a direct deposit, automatic payment, or wire transfer, confirm you are dealing with the correct organization. Scammers sometimes impersonate payroll departments or utility companies to collect account numbers.

Frequently Asked Questions

Is my account number the same as my routing number?

No. Your routing number identifies your bank (nine digits), while your account number identifies your specific account at that bank (typically 10 to 12 digits). Both appear on the bottom of a check, with the routing number first and the account number second.

Can I use an old check to find my current account number?

Yes. Your account number does not change unless you close the account and open a new one. A check from years ago will show the same account number you use today.

What if my bank statement only shows the last four digits?

Call your bank's customer service line or visit a branch with your ID. They will provide your full account number. Some banks mask the number on statements for security but will give you the complete number when you request it.

Do I need both my routing number and account number?

Yes, for most banking transactions like direct deposit or wire transfers. The routing number tells the system which bank to use, and the account number tells it which account within that bank. Both are required together.

Is it safe to give my account number to my employer for direct deposit?

Yes, your employer needs your routing number and account number to set up direct deposit. This is a standard, secure process. Only provide these numbers directly to your employer's payroll department, not to anyone claiming to represent them.
