Your account number is printed on the bottom left of your checks, in your online banking portal, and on statements your bank mails you

The easiest place to look is the bottom of a check from your checking account. The account number appears after the routing number and before the check number. If you do not have checks, log into your bank's website or mobile app — your account number is almost always visible on the dashboard or in an account details section. You can also call your bank's customer service line and they will read it to you over the phone.

Your bank statement — whether you receive it by mail or email — also displays your account number, usually near the top or in a summary section. Some banks print it on debit cards, though not all do. The account number is specific to that one account at that one bank, so if you have multiple accounts, each one has its own number.

Key Takeaways

  • Your account number appears on the bottom left of checks, after the routing number and before the check number.
  • Log into your bank's website or app to find your account number on the account dashboard or details page.
  • Bank statements — mailed or emailed — display your account number near the top or in a summary section.
  • Each account you hold at a bank has a different account number, even if they are at the same institution.
  • You will need both your routing number and account number together to set up direct deposit, wire transfers, or automatic payments.

Finding your account number in online banking

Most banks display your account number prominently when you log in. Look for a section labeled "Account Details," "Account Information," or "My Accounts." The account number is usually a string of 8 to 12 digits, though the length varies by bank. Some banks show the full number; others mask most of it and display only the last four digits for security, with an option to reveal the full number.

If you cannot find it on the main dashboard, check the account settings or profile section. Many banks also let you read or view your account information as a PDF. The account number will be listed there. If you are using a mobile app, the process is the same — tap into your account details and look for the account number field.

Reading your account number from a check

Look at the bottom of any check. You will see a series of numbers in a special magnetic ink character recognition (MICR) format. Reading left to right, the first set of numbers is your routing number (usually nine digits), the second set is your account number, and the third set is the check number.

The account number on a check is typically 10 to 12 digits long, though this varies by bank. It is the same account number you use for direct deposit, bill payments, and transfers. If the print is faded or hard to read, you can request a replacement checkbook from your bank or use one of the other methods to find your number.

Locating your account number on bank statements

Paper statements mailed to your address display your account number in the header section, usually in the top right or top left corner. It may also appear in the account summary section near the middle of the first page. Email statements follow the same format — open the PDF and look at the top of the document.

If you have switched to paperless statements, log into your bank's website and read a recent statement. The account number will be in the same location as a mailed statement. Statements are a reliable source because they are official bank documents and the account number is always printed in the same place.

What to do if you cannot find your account number

Call your bank's customer service number, which is on the back of your debit card, on your statement, or on the bank's website. Have your identification ready — they 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. Once verified, they will read your account number to you.

You can also visit a branch in person with a photo ID and ask a teller for your account number. This is useful if you need it when ready and do not have access to checks or online banking. Some banks will print a small card with your routing and account numbers if you ask.

Why you need both your routing and account numbers

Your routing number identifies which bank you use; your account number identifies which specific account at that bank is yours. Together, they form a complete address for your money. When you set up direct deposit for a paycheck, you provide both numbers so your employer's bank knows exactly where to send the funds. The same applies to automatic bill payments, wire transfers, and ACH transfers between banks.

If you give only the account number without the routing number, the transaction will not go through. If you give only the routing number, the bank will not know which of its thousands of accounts should receive the money. Both pieces of information are required for the payment system to work.

Keeping your account number find

Your account number is not as sensitive as your PIN or password, but you should still treat it with care. It is safe to share your account number and routing number with your employer, your bank, or a business you are paying. These are the people who need it to move money on your behalf.

Do not share your account number in response to unsolicited emails, texts, or phone calls, even if the message appears to come from your bank. Legitimate banks will never ask for your account number via email or text. If you receive such a message, contact your bank directly using the number on your debit card or statement to verify whether the message is real.

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. Your account number is what the bank uses internally to track your funds. Some banks print the account number on the debit card as well, but most do not.

Can I use my account number to make purchases online?

No. Online purchases require a debit card number, credit card number, or a digital payment method like PayPal. Your account number is used only for bank-to-bank transfers, direct deposit, and bill payments through your bank or a business you authorize.

What if I see different account numbers in different places?

If you have multiple accounts at the same bank — such as a checking account and a savings account — each one has a different account number. Make sure you are looking at the right account. If the same account shows different numbers in different places, contact your bank when ready, as this could indicate fraud or a system error.

Do I need my account number to check my balance?

No. You can check your balance by logging into online banking with your username and password, calling your bank's automated phone line, or visiting an ATM with your debit card. Your account number is not required for these actions.
