Your bank account number is printed on the bottom left of your checks, shown in your online banking portal, and available by calling your bank's customer service line.
The easiest place to look is the bottom of any check you have. Your account number appears as a string of digits between two sets of routing numbers — the routing number comes first on the left, then your account number, then the check number on the right. If you don't have checks handy, log into your bank's website or mobile app and look for account details or account information. Most banks display your full account number there.
If you can't find it online, call the customer service number on the back of your debit card or on your bank statement, and a representative can read it to you over the phone. You'll need to verify your identity first, usually with your name, date of birth, and the last four digits of your Social Security number.

Finding Your Account Number on a Check
The bottom of a check contains three separate numbers in a specific order. On the far left is your bank's routing number, a nine-digit code that identifies your financial institution. Immediately after that is your account number, which is typically nine to twelve digits long depending on your bank. On the far right is the individual check number.
The numbers are printed in a special magnetic ink that allows banks to process checks automatically. If you look closely, you'll see the digits are slightly raised and have a distinctive appearance. This layout is standard across nearly all U.S. banks, so once you know where to look on one check, you'll recognize it on any other check from the same account.
Checking Your Online Banking Portal
Log into your bank's website using your username and password. Most banks place account information in a dashboard or summary page that appears when you first log in. Look for a section labeled "Account Details," "Account Information," or "My Accounts." Click on the specific account you need information for, and your full account number should display on that page.
Mobile banking apps follow the same layout. Open the app, navigate to your account, and tap on the account name or an information icon. Your account number will appear alongside your current balance and recent transactions. If you're having trouble locating it in the app, check the bank's help section or contact customer service — they can walk you through the steps for your specific app version.
Calling Your Bank Directly
The customer service number for your bank appears on the back of your debit card, on your monthly bank statement, or on the bank's website. When you call, have your name, date of birth, and the last four digits of your Social Security number ready. The representative will verify your identity using this information before providing your account number.
Customer service lines are typically available during business hours, though many banks now offer 24/7 phone support. If you call during off-hours, you may reach an automated system that can direct you to the information you need or allow you to schedule a callback with a representative during business hours.
Locating Your Account Number on Bank Statements
Your monthly bank statement includes your account number, usually printed near the top of the page alongside the statement date and your name. If you receive paper statements in the mail, keep at least one recent statement in a safe place for reference. If you receive electronic statements, you can download and save them to your computer or phone.
To access past statements, log into your online banking portal and look for a section called "Statements," "Documents," or "History." You can usually download statements from the past several years as PDF files. This is useful if you need to reference your account number but don't have a current statement or check available.
What to Do If You Can't Find Your Account Number
If you've checked your checks, your online portal, and your statements and still can't locate your account number, contact your bank by phone. This is the most direct route and takes only a few minutes. Have your identification ready, and the representative can provide your account number immediately.
If you're locked out of your online account or can't remember your login credentials, call customer service and ask for help resetting your password. Once you regain access, you can view your account number in the portal. Some banks also allow you to request a new set of checks, which will include your account number printed on them.
Keeping Your Account Number Secure
Your account number is sensitive information. Don't share it with anyone unless you initiated the contact and are certain you're dealing with your actual bank. Legitimate banks will never ask for your full account number via email or unsolicited phone calls. If someone contacts you claiming to be from your bank and asks for your account number, hang up and call your bank directly using the number on your debit card or statement.
When you need to provide your account number for direct deposit, bill payments, or wire transfers, verify that you're sending it through a secure channel. Use your bank's official website or app, or call the organization requesting the information to confirm you have the correct contact details. Scammers sometimes impersonate businesses or banks to trick people into sharing account information.
Frequently Asked Questions
Is my account number the same as my routing number?
No. Your routing number identifies your bank, while your account number identifies your specific account within that bank. Both appear on the bottom of your checks, but they are separate numbers. You need both to set up direct deposit or wire transfers.
Can I use my debit card number instead of my account number?
No. Your debit card number is different from your account number. Some organizations may accept a debit card number for payment, but if they specifically ask for your account number, you must provide the correct one. Using the wrong number can cause delays or failed transactions.
What if I have multiple accounts at the same bank?
Each account has its own unique account number. If you have a checking account and a savings account, they will have different account numbers. When you need to provide an account number, make sure you're giving the number for the correct account.
Do I need my account number to use my debit card?
No. Your debit card works with just the card number, expiration date, and CVV code. You only need your account number when setting up direct deposit, authorizing automatic payments, or conducting banking transactions that require account-level information.
Is it safe to write my account number down?
It's safer to store it in a password-protected document on your computer or phone than to write it on paper. If you do write it down, keep it in a secure location like a locked drawer or safe. Never leave it visible on a desk or in a wallet where others can see it.
