Check your checks or debit card

Your bank account number appears on the bottom left of every check you write. Look at the string of numbers below the routing number — that longer number is your account number. If you do not have checks handy, your debit card statement or the back of your debit card itself may also display it, though some banks print only the last four digits on the card for security.

This is the fastest way to find it if you have physical banking materials at home. The account number is usually between 8 and 12 digits long, depending on your bank. The exact position and format can vary slightly by institution, but it will always be printed below the routing number on any check.

Log into your online banking portal

Nearly every bank displays your full account number in the account details section of its website or mobile app. Sign in with your username and password, then look for a tab labeled "Account Information," "Account Details," or "My Accounts." Your account number will be listed there alongside your account type and current balance.

If you cannot find it in the main account view, try clicking on the specific account you need — some banks hide the full number until you drill down into that account's settings. The mobile app usually shows the same information as the website version. This method takes seconds and works from anywhere you have internet access.

Call your bank's customer service line

The phone number on the back of your debit card connects you to customer service representatives who can read your account number to you over the phone. Have your Social Security number or card number ready so they can verify your identity before sharing the information.

This method takes longer than checking online or your checks, but it works if you have lost access to your online account or do not have physical banking materials. Most banks have customer service available during business hours and some offer 24/7 support. Write down the number they give you so you have it for future reference.

Visit your bank branch in person

Walk into any branch of your bank with a photo ID and ask a teller for your account number. They will verify your identity and provide it immediately. You can also ask them to write it down for you or print a statement that shows it.

This is useful if you prefer face-to-face verification or if you need other account information at the same time. Bring your ID and be prepared to answer security questions about your account. Tellers can also explain any account features or answer questions about your specific banking setup.

Look at your bank statements

Paper statements mailed to your home and digital statements in your online account both display your account number at the top or in the account summary section. If you receive paper statements, check the most recent one in your files. If you have gone paperless, log into your account and download or view a recent statement.

Statements are useful because they also show your routing number in the same place, which you may need together for wire transfers or setting up direct deposit. Keep a copy of your statement in a safe place for future reference, since you may need both numbers again.

Check your direct deposit or wire transfer paperwork

If you have set up direct deposit for paychecks, tax refunds, or government payments, the confirmation email or document from that setup process will contain your account number. The same applies to any wire transfer you have received — the bank's confirmation will list both your routing number and account number.

This works only if you have completed one of these transactions before, but it is a good place to look if you have already provided the number to an employer or government agency. Search your email for messages from your employer's payroll department or from the IRS if you have received a refund deposit.

Frequently Asked Questions

Is it safe to share my account number?

Your account number alone cannot be used to withdraw money without your routing number and other information. However, share it only with people and organizations you trust — your employer for direct deposit, your bank, government agencies processing refunds, and established businesses you are paying. Never share it in response to unsolicited calls or emails.

What if I cannot remember my online banking password?

Use the "Forgot Password" link on your bank's login page to reset it. You will need to verify your identity using your email address, phone number, or security questions. Once you reset the password, you can log in and find your account number immediately.

Can I find my account number on my tax return or refund paperwork?

If you provided your account number when filing your tax return or setting up a refund deposit, the IRS confirmation or your state tax agency's receipt may show it. Check any emails or documents from the tax filing process. If you cannot find it there, use one of the other methods listed above.

Do I need both my routing number and account number together?

Yes, for most banking transactions like direct deposit or wire transfers, you need both numbers. Your routing number identifies your bank; your account number identifies your specific account within that bank. Both appear on your checks in the same location at the bottom.
