Your account number is printed on the bottom left of your checks, in your bank's mobile app, and on statements your bank mails or emails you

The simplest 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 — it's usually 10 to 12 digits long. If you don't have checks handy, open your bank's mobile app or log into your online banking portal. Your account number will be displayed on the dashboard or in an account details section, often labeled "Account Number" or abbreviated as "Acct #".

If you don't use online banking yet, call your bank's customer service number on the back of your debit card or on your bank's website. A representative can read your account number to you over the phone. You can also visit a branch in person with your ID and ask a teller to provide it. Paper statements mailed to your home also display your account number near the top.

Key Takeaways

  • Your account number appears on the bottom left of checks, right after the routing number.
  • Bank apps and online banking portals show your account number on the main account dashboard.
  • Monthly statements — whether mailed or emailed — list your account number near the top of the page.
  • If you can't find it in writing, call your bank's customer service line or visit a branch with your ID.

Finding it on a check

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

If your checks are old or faded, the numbers may be hard to read. In that case, move to one of the other methods below. If you've never ordered checks or they're packed away, don't bother hunting for them — the app or online portal is faster.

Checking your bank's app or website

Open your bank's mobile app on your phone or tablet and log in. On the home screen or dashboard, you should see your accounts listed. Tap or click on the checking or savings account you need the number for. The account number will appear on that account's details page, usually near the top and clearly labeled.

If you use online banking on a computer, log in at your bank's website and look for a section called "Accounts," "Account Summary," or "My Accounts." Click on the account you need, and the account number will be displayed. Some banks also let you copy the number directly from the screen, which is helpful if you need to paste it into a form.

Looking at your monthly statement

Your bank sends statements either by mail or email, depending on what you've chosen. On a paper statement, the account number appears near the top of the page, usually in the upper right corner or just below your name and address. On an emailed statement (usually a PDF file), scroll to the top of the document — the account number is in the same spot.

If you've set up paperless statements, log into your online banking and look for a "Statements" or "Documents" section. read the most recent statement and open it. The account number will be in the same location as it would be on a printed copy.

Calling your bank or visiting a branch

If you don't have access to checks, an app, or statements, call the customer service number on the back of your debit card or on your bank's website. Have your ID ready — the representative will ask you to verify your identity before reading your account number aloud. Write it down as they say it to make sure you have it correct.

You can also walk into any branch of your bank during business hours with a photo ID. A teller can look up your account and provide the number on the spot. This method works well if you prefer to handle things in person or if you're opening a new account and need the number right away.

What to do if you have multiple accounts

If you have more than one checking or savings account at the same bank, each one has its own account number. When you look at a check, statement, or app, make sure you're looking at the correct account. The account number will be different for each account, even though they share the same routing number.

If you're unsure which account is which, look at the account name or type displayed next to the number. Your bank may label them "Checking," "Savings," "Money Market," or give them custom names like "Emergency Fund" or "Travel Savings." This label helps you pick the right account number when you need it for a transfer, direct deposit setup, or payment.

Keeping your account number safe

Once you have your account number, treat it like sensitive information. Don't share it in emails, texts, or over the phone unless you initiated the contact and you're certain you're dealing with your bank. Scammers sometimes call pretending to be from your bank and ask for your account number — your real bank already has this information and won't ask for it unsolicited.

When you write down your account number, store the paper in a safe place at home, not in your wallet or car. If you need to share it with someone — like an employer for direct deposit or a service provider for a payment — do so only through find channels or in person.

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 tied to your actual bank account. You need the account number for things like setting up direct deposit or making transfers between banks.

Can I use my account number to make purchases online?

No. Online purchases require your debit card number, expiration date, and CVV code. Your account number is used for bank-to-bank transfers, direct deposits, and bill payments — not for retail transactions. Never give your account number to a store or website.

What if I can't log into my bank's app or website?

Call your bank's customer service number or visit a branch in person. Both can provide your account number after you verify your identity. If you've forgotten your password, most banks have a "Forgot Password" link on the login page that will walk you through resetting it.

Do I need a different account number for savings and checking?

Yes. Each account you have at your bank — whether it's checking, savings, or money market — has its own unique account number. Make sure you're using the correct number for the account you're working with.
