Your account number is printed on the bottom left of your checks, or you can find it online through your bank's website or mobile app

The account number is a unique identifier your bank assigns to your specific checking or savings account. It is different from your routing number, which identifies the bank itself. You will need both numbers together to set up direct deposit, make wire transfers, or authorize automatic payments.

The fastest way to find it depends on what you have access to right now. If you have a checkbook, look at the bottom of any check. If you do not have checks or they are not handy, log into your bank's website or open the mobile app — your account number will be displayed in the account details section, usually on the main dashboard or under "Account Information."

Key Takeaways

  • Your account number appears on the bottom left of your checks, between the routing number and the check number.
  • You can find your account number by logging into your bank's website or mobile app under account details or account information.
  • If you call your bank's customer service line, they can read your account number to you after verifying your identity.
  • Some banks print the account number on bank statements, deposit slips, and debit cards, though not all do.
  • Never share your full account number with anyone unless you initiated the transaction or verified the recipient is legitimate.

Finding it on a check

Look at the bottom of any check you have written or received. You will see three sets of numbers printed in magnetic ink. Reading from left to right, the first set is your routing number (nine digits), the second set is your account number (usually 10 to 12 digits), and the third is the check number.

The account number is the longer middle section. Write it down exactly as it appears, including any leading zeros. If your checks are old or the ink is faded, the numbers may be hard to read — in that case, use one of the other methods below instead of guessing.

Finding it online through your bank

Log into your bank's website using your username and password. On the main dashboard or home page, you should see a summary of your accounts. Click on the account you need the number for, and look for a section labeled "Account Details," "Account Information," or "Account Summary." Your account number will be displayed there.

If you use your bank's mobile app, the process is the same. Open the app, navigate to the account you need, and tap into the account details section. Some banks display the full account number; others show only the last four digits on the main screen but reveal the full number when you tap "View Details" or a similar option.

Finding it on bank statements and other documents

Your account number often appears at the top of your monthly bank statement, usually in the upper right corner or near your name and address. If you have a deposit slip from your bank, the account number is printed on it as well. Some banks also print it on the back of your debit card, though this is less common.

If you have recently opened the account and have not yet received a statement, check any welcome letter or account confirmation email from the bank — these sometimes include the account number for your reference.

Calling your bank to get the number

If you cannot find your account number through any of the above methods, call your bank's customer service line. The number is on the back of your debit card, on your bank statements, or on the bank's website. Be prepared to verify your identity by providing your full name, date of birth, and possibly the last four digits of your Social Security number or a recent transaction amount.

Once verified, the representative will read your account number to you. Ask them to spell it out or repeat it so you can write it down correctly. If you are calling about a specific transaction, let them know — they may be able to help you with the next step as well.

What to do if you cannot locate your account number

If you have tried all the above methods and still cannot find it, the fastest solution is to call your bank directly. Do not guess or use a partial number — an incorrect account number can send money to the wrong account or cause a transaction to fail.

If you are trying to set up direct deposit for payroll or a government benefit, your employer or the benefit program can usually contact your bank on your behalf to verify the account number once you provide it. Some programs will also accept a voided check as proof of the account and routing number, which eliminates the need to type the numbers yourself.

Protecting your account number

Your account number is sensitive information. Do not share it with anyone unless you initiated the contact or you have verified that the person or organization is legitimate. Scammers sometimes call or email claiming to be from your bank and ask for your account number — your bank will never ask for this information unsolicited.

If you are making a payment or setting up a transfer, confirm you are using the correct website or phone number for your bank. Type the bank's web address directly into your browser rather than clicking a link in an email, and call the number on the back of your debit card rather than using a number from an email or text message.

Frequently Asked Questions

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

No. Your debit card number is a separate 16-digit number printed on the front of your card. Your account number is typically 10 to 12 digits and is not printed on the card itself, though some banks do print it on the back. You need the account number for bank transfers and direct deposit, not for card purchases.

Can someone access my account if they know my account number?

Not without additional information. Your account number alone is not enough to transfer money out of your account. Someone would also need your routing number, and depending on the transaction type, they may need your PIN, password, or other verification. That said, do not share your account number with people you do not trust.

What if I have multiple accounts at the same bank?

Each account has its own unique account number. When you log into your bank's website or app, you will see all your accounts listed separately, each with its own number. Make sure you are looking at the correct account before you write down the number, especially if you have both checking and savings accounts.

Do I need my account number to use my debit card at a store?

No. You only need your debit card number, expiration date, and CVV (the three-digit security code on the back) to make purchases online or over the phone. Your account number is used for bank-to-bank transfers, direct deposit, and automatic bill payments — not for everyday card transactions.

What if my bank statement shows a different account number than my checks?

This is unusual and suggests either a printing error or that you are looking at the wrong account. Call your bank to confirm which number is correct. Do not use a number you are unsure about, as it could cause a transaction to fail or go to the wrong place.
