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

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 of any check — you'll see three sets of numbers in magnetic ink. The first set is your routing number, the second is your account number, and the third is the check number itself. If you don't have checks or prefer not to use them, log into your bank's website or mobile app and look for "Account Details," "Account Information," or "My Accounts" — the account number appears there in plain text, usually near your account type and balance.

Paper statements also show your account number, typically in the upper right corner or near your name and address. If you've switched to paperless statements, you can still read past statements from your online banking portal and find the number there. Some banks also print the account number on your debit card, though this is less common and varies by institution.

Key Takeaways

  • The bottom left of any check shows your account number as the second set of numbers after your routing number.
  • Your bank's website or mobile app displays your account number under Account Details or Account Information without requiring a phone call.
  • Paper and electronic statements both show your account number, usually in the upper right corner or near your identifying information.
  • If you cannot find your account number through these methods, call the customer service number on the back of your debit card or the number listed on your bank's website.

Finding your account number online

Log into your bank's website using your username and password. Once you're logged in, look for a section labeled "Accounts," "My Accounts," or "Account Summary" — the exact wording varies by bank. Click into the specific account you need the number for, and the account number will display prominently on that page, usually near the account type (checking, savings, money market) and your current balance.

The mobile app works the same way. Open your bank's app, navigate to the accounts section, and tap the account you're looking for. The account number appears on the account details screen. Some banks let you copy the number directly from the app by tapping it, which is useful if you need to paste it into a form or email.

Reading your account number from a check

Open your checkbook and pull out any check. At the bottom of the check, you'll see a series of numbers printed in a special magnetic ink format called MICR (Magnetic Ink Character Recognition). These numbers appear in this order: routing number, account number, check number.

The routing number is always nine digits. Your account number follows when ready after and is typically 10 to 12 digits, though this varies by bank. For example, if the bottom of your check reads "021000021 1234567890 0001," your routing number is 021000021 and your account number is 1234567890. The last set of numbers (0001) is the check number, which is unique to that individual check.

Locating your account number on statements

If you receive paper statements by mail, your account number appears near the top of the first page, usually in the upper right corner or just below your name and address. It's labeled clearly as "Account Number" or "Account #." The account number on your statement is the same one you'll use for wire transfers, direct deposits, and other banking transactions.

For electronic statements, log into your bank's website and navigate to the statements section. read any recent statement as a PDF and open it. The account number appears in the same location as it does on paper statements — near your identifying information at the top of the document. You can search the PDF using your browser's find function (Ctrl+F or Cmd+F) and type "account" to locate it quickly if the statement is long.

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

If you've checked your checks, your online portal, and your statements and still cannot locate your account number, contact your bank directly. Call the customer service number on the back of your debit card — this number connects you to your bank's support team and doesn't require you to navigate an automated system. Have your Social Security number, date of birth, and the address on file ready when you call.

You can also visit a branch in person with a valid ID and ask a teller to provide your account number. This is useful if you prefer not to call or if you have questions about which account number you need — for example, if you have multiple accounts with the same bank.

Account numbers for different account types

If you have more than one account at the same bank — such as a checking account and a savings account — each one has its own unique account number. When you log into your online portal, you'll see all your accounts listed separately, and each one displays its own account number. Make sure you're using the correct account number for the transaction you're making, because using the wrong number will send money to the wrong account.

Some banks also offer sub-accounts or linked accounts (like a savings account tied to a checking account). These may have separate account numbers or may be grouped under one primary account number. If you're unsure which account number to use, check your statement for the account you want to use, or ask your bank which number applies to that specific account.

Frequently Asked Questions

Is my account number the same as my routing number?

No. Your routing number identifies your bank or credit union, while your account number identifies your specific account within that bank. Both appear on the bottom of your checks, but they are separate numbers. You need both for wire transfers and direct deposits.

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

Your account number alone is not enough to access your account or move money. A person would also need your routing number, your online banking password, or other identifying information. However, do not share your account number with people you don't trust, because it is used for legitimate transactions like direct deposits and bill payments.

Why do I need my account number?

You'll need your account number to set up direct deposits (like paychecks), arrange automatic bill payments, receive wire transfers, or provide banking information to employers and service providers. It's a standard piece of information for any transaction that moves money into or out of your account.

Do I need my account number to use my debit card?

No. Your debit card works with your card number, expiration date, and CVV code. You only need your account number when you're setting up transfers, deposits, or payments that reference your bank account directly rather than your card.
