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

The easiest place to look is the bottom of any check you have. The account number appears after the routing number — it's the second set of digits on that bottom line. If you don't have checks handy, log into your bank's website or mobile app and look for "Account Details" or "Account Information." Your statement — either the paper one mailed to you or the digital version in your online account — also shows your account number near the top.

If you've just opened your account and haven't received checks yet, the bank sent you a welcome packet with this number. Check any letters from your bank, or call the customer service number on the back of your debit card. They can read it to you over the phone.

Key Takeaways

  • Your account number appears on the bottom left of your checks, right after the routing number.
  • You can find it by logging into your bank's website or app under Account Details or Account Information.
  • Paper and digital statements both display your account number near the top of the document.
  • If you don't have checks or online access yet, call your bank's customer service line to get the number read to you.

Finding it on a check

Look at the bottom of any check. You'll see a line of numbers printed in a special magnetic ink. Reading from left to right, the first set of numbers is your routing number (usually nine digits), and the second set is your account number. The account number is typically between 10 and 12 digits long, though this varies by bank.

The account number is the one you'll use when you need to receive money — for direct deposit of a paycheck, for example, or when someone wants to send you a wire transfer. The routing number tells the sending bank which bank to send the money to; the account number tells your bank which account within that bank is yours.

Checking your online account

Log into your bank's website or open the mobile app. Look for a section called "Account Details," "Account Information," "My Accounts," or sometimes just "Accounts." Your account number will be displayed there, usually near your account type (like "Checking" or "Savings") and your current balance.

Some banks also let you copy the account number directly from this screen, which is useful if you need to paste it into a form. If you can't find this section, look for a question mark icon or "Help" button — most banks have a search function where you can type "account number" and it will take you to the right page.

Looking at your statement

Whether you receive a paper statement in the mail or view it online, your account number appears near the top of the first page. It's usually listed alongside your account type and the statement date. Digital statements are often easier to search — you can use your browser's find function (Ctrl+F on Windows, Cmd+F on Mac) and type "account number" to jump straight to it.

Statements are sent monthly, though some banks let you view them online as soon as the month ends. If you haven't received a statement yet because your account is brand new, the welcome materials your bank sent should include this information.

What to do if you can't find it

Call the customer service number on the back of your debit card or on your bank's website. Have your ID ready — the bank will ask you to verify who you are before reading the number aloud. This usually takes less than five minutes. You can also visit a branch in person with your ID, and a teller can write it down for you.

If you're locked out of your online account, the bank can help you reset your password or username so you can log back in and find the number yourself. This is often faster than waiting on the phone.

Why you need both numbers

Your routing number and account number work together. The routing number is like your bank's address — it tells any other bank where to send money. Your account number is like your mailbox number at that address — it tells your bank which account should receive the money. You need both when you set up direct deposit, arrange a wire transfer, or give someone permission to withdraw money from your account.

Some forms ask for both numbers together on one line, written as "routing number-account number." Others have separate fields. Either way, the order matters: routing number first, then account number.

Keeping your account number safe

Your account number is not as sensitive as your PIN or password, but you should still treat it carefully. It's safe to share your account number and routing number with your employer (for direct deposit) or with someone sending you money. However, don't share it with people you don't trust, and don't post it on social media or in public forums.

If you suspect someone has misused your account number, contact your bank right away. Banks can monitor for unauthorized activity and reverse fraudulent transactions in many cases, especially if you report them quickly.

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. The account number is what's printed on your checks and in your online account. You need the account number for direct deposit and wire transfers, but you use the debit card number when you swipe or tap to pay.

Can I use my account number to make purchases online?

No. Online purchases require your debit card number, expiration date, and CVV (the three-digit code on the back). Your account number is for bank-to-bank transfers and direct deposit, not for shopping. Never enter your account number on a retail website.

What if I have multiple checking accounts at the same bank?

Each account has its own account number. If you have a checking account and a savings account, they have different numbers. Make sure you're using the correct one for what you're trying to do — using the wrong account number means money will go to the wrong place.

Do I need my account number to set up online banking?

Usually not. You typically set up online banking with your Social Security number, date of birth, and other identifying information. Once you're logged in, you can see your account number. If you already have online access, you don't need to memorize the number — you can always look it up when you need it.
