The fastest way: check your checks or debit card

Your bank account number is printed on the bottom left of every check you have. It comes after the routing number and before the check number on the far right. If you do not have checks, look at your debit card — many banks print the last four digits of your account number on the front or back, though this is not universal.

If neither of those works, your next fastest option is to log into your bank's website or mobile app. Once you are signed in, look for a section called "Account Details," "Account Information," or sometimes just "Accounts." Your full account number will be listed there.

Key Takeaways

  • Your account number appears on the bottom of every check you write, right after the routing number.
  • Your bank's website or mobile app shows your full account number in the account details section once you log in.
  • You can call your bank's customer service line and give them your name and Social Security number to confirm your account number over the phone.
  • Bank statements — whether printed or digital — list your account number at the top or in the account summary section.

Finding it on your bank statement

If you have a recent bank statement, your account number is usually printed near the top of the page, often next to your name and address. On digital statements you receive by email, it appears in the same place. Some banks put it in a summary box; others list it as part of the account header.

This method works whether your statement is from last month or several months ago — your account number does not change unless you close the account and open a new one.

Calling your bank directly

If you cannot locate your account number through any of the above methods, call the customer service number on the back of your debit card or on your bank's website. Have your name, date of birth, and Social Security number ready. The representative will verify your identity and read your account number to you.

This call is free and takes about five minutes. You do not need to visit a branch in person.

What to do if you have multiple accounts

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 account number. When you log into your online banking, you will see all your accounts listed separately, each with its own number.

Make sure you are looking at the correct account before you use the number. If you are setting up a direct deposit for your paycheck, for example, you need the account number for the account where you want the money to land, not just any account you have at that bank.

Account numbers and security

Your account number by itself is not enough for someone to drain your account — they also need your routing number and usually additional verification. However, treat your full account number the same way you treat your debit card number: do not share it with people you do not trust, and do not type it into websites unless you initiated the contact and you are certain the site is legitimate.

If you are giving your account number to set up direct deposit, a wire transfer, or an automatic payment, make sure you are doing so through your employer's payroll system, your bank's official website, or a company you called yourself — not through a link someone sent you.

Why you need your account number

Your account number is required for direct deposit, wire transfers, automatic bill payments, and when you need to send money to someone else's account. It is also what your bank uses to identify your account when you call customer service or visit a branch.

The account number is specific to you and that particular account. Your routing number (which identifies your bank) stays the same for all your accounts at that bank, but your account number is unique to each individual account you hold.

Frequently Asked Questions

Is my account number the same as my debit card number?

No. Your debit card number is different from your account number. Some banks print the last four digits of your account number on your debit card for reference, but the full card number is separate. You need your account number for transfers and direct deposit, not your card number.

Can I use my account number instead of my card to make purchases?

No. Your account number is for bank-to-bank transfers and direct deposits. To make purchases, you use your debit card, credit card, or online payment services like Venmo or PayPal. Stores and online retailers do not accept account numbers as payment.

What if I cannot remember my online banking password?

Most banks have a "Forgot Password" link on their login page. Click it and follow the steps to reset your password using your email address or phone number. You do not need to call the bank unless the reset process does not work.

Do I need my account number to open a savings account at the same bank?

No. When you open a new account, the bank will assign you a new account number. You do not need your existing account number to open another one, though you may be asked to verify your identity using information from your current account.
