Your account number is the unique identifier your bank assigns to your specific checking or savings account
Your account number is a string of digits — usually between 8 and 17 characters long, though the exact length varies by bank — that identifies your individual account within your bank's system. It is not the same as your routing number, which identifies the bank itself. You need both pieces of information together to receive direct deposits, set up automatic bill payments, or send wire transfers.
The account number appears on almost every piece of paper your bank sends you. It is printed on the bottom of your checks, in your online banking portal, on your monthly statements, and on any debit card documentation. If you have lost access to these sources, your bank can tell you the number in seconds over the phone or through their website.
Key Takeaways
- Your account number is printed on the bottom left of your checks, right after the routing number.
- You can find your account number in your online banking portal, on your monthly statement, or by calling your bank's customer service line.
- The account number alone is not enough to access your account — you also need the routing number and your personal identification to complete most transactions.
- Different accounts at the same bank have different account numbers, so a checking account and savings account will each have their own unique identifier.
Where to find your account number on a check
If you have a checkbook, the easiest place to find your account number is at the bottom of any check. The bottom of a check displays three sets of numbers in this order: the routing number (9 digits), your account number, and the check number. The account number is the middle set and is typically 10 to 12 digits long, though this varies by bank.
The routing number always comes first on the left. Your account number follows immediately after. The check number appears on the far right. If you are unsure which set is which, your bank's website or a quick phone call can confirm, but the middle set at the bottom of the check is almost always your account number.
Finding your account number online or through your bank app
Log into your bank's website or mobile app and navigate to your account details or account summary page. Most banks display your account number prominently near the top of the page, often labeled "Account Number" or "Checking Account" or "Savings Account" depending on which account you are viewing. Some banks require you to click a link or button to reveal the full number for security reasons.
If you cannot locate it in the obvious place, look for a section called "Account Information," "My Accounts," or "Account Details." You may also find it on your digital statements or transaction history. If your bank's app or website does not show the account number clearly, call customer service — they can read it to you over the phone after you verify your identity.
Getting your account number from your monthly statement
Your bank's monthly statement lists your account number near the top, usually in a section labeled "Account Information" or "Your Account." It appears on both paper statements and digital statements you download or view online. The statement also includes your routing number, so you will have both pieces of information in one place if you need them together.
If you receive paper statements by mail, keep one in a safe place for reference. If you receive digital statements only, you can download and save a PDF copy to your computer or phone for future use. Statements are typically available online for at least one year, so you can retrieve an older statement if your current one is not handy.
Calling your bank to confirm your account number
Call the customer service number on the back of your debit card or on your bank's website. Have your Social Security number, date of birth, and the last four digits of your card or account number ready to verify your identity. Once the representative confirms who you are, they will read your account number to you.
This method takes only a few minutes and is the safest option if you are not comfortable sharing your account number online or if you cannot access your statements or online banking. Some banks also allow you to retrieve your account number through their automated phone system without speaking to a representative, though you will still need to verify your identity.
Why you should not share your account number carelessly
Your account number alone cannot be used to drain your account — a person would also need your routing number, your name, and often additional verification to complete a transaction. However, sharing your account number with unknown people or on unsecured websites increases the risk that someone could attempt unauthorized transactions or use the information for fraud.
Share your account number only with people and organizations you trust, such as your employer for direct deposit, your landlord for rent payments, or established companies you do business with. Never share it in response to an unsolicited email, text, or phone call, even if the sender claims to be from your bank. Your bank will never ask you to confirm your account number via email or text.
Account numbers for different account types
If you have multiple accounts at the same bank — such as a checking account and a savings account — each one has its own unique account number. When you set up direct deposit or automatic payments, make sure you are using the correct account number for the account you want the money to go into. Using the wrong account number will send the funds to the wrong place.
You can find all your account numbers by logging into your online banking portal and viewing each account separately, or by calling your bank and asking them to list all your accounts and their corresponding numbers. Keep a record of each account number in a safe place so you have them available when you need them.
Frequently Asked Questions
Is my account number the same as my card number?
No. Your card number is the 16-digit number printed on the front of your debit or credit card. Your account number is a separate identifier that your bank uses internally. They are not interchangeable, and you should not use one in place of the other.
Can someone access my account with just my account number?
Not easily. A person would need your account number, routing number, your name, and usually additional verification such as your Social Security number or answers to security questions. Sharing your account number alone is lower risk than sharing your full banking details, but it is still best to share it only with trusted sources.
What if I cannot find my account number anywhere?
Call your bank's customer service line at the number on the back of your debit card or on their website. Have your identification ready, and they will provide your account number within minutes. This is the fastest and most reliable way to get the information if other sources are not available.
Do I need both my account number and routing number for direct deposit?
Yes. Direct deposit requires both your routing number and your account number. The routing number tells the employer's bank which bank to send the money to, and the account number tells your bank which account to deposit it into. You cannot complete direct deposit with just one of these numbers.
Will my account number change if I close and reopen an account?
Usually yes. If you close an account and later open a new one at the same bank, the new account will have a different account number. If you reopen the same account after a brief closure, you may get the same number back, but this depends on your bank's policies. Contact your bank to confirm before setting up any recurring payments.
