Your checking account number is printed on the bottom left of every check you write, and also appears in your online banking portal under account details or settings.
The easiest place to look is a check from your checkbook. Pick up any check and look at the bottom left corner. You will see three groups of numbers separated by vertical lines. The middle group is your account number. It is usually 10 to 12 digits long, though the length varies by bank.
If you do not have checks handy, log into your bank's website or mobile app. Most banks display your account number prominently on the dashboard or in a section labeled "Account Details," "Account Information," or "My Accounts." Some banks require you to click into a specific account to see the full number.
Key Takeaways
- Your account number appears on the bottom left of any check, in the middle group of numbers between two vertical lines.
- Online banking portals show your full account number under account details, account information, or a similar section in settings.
- You can also call your bank's customer service line and provide your name and Social Security number to confirm your account number over the phone.
- Never share your full account number with anyone unless you initiated the contact and trust the recipient completely.
Finding it in your online banking account
Log into your bank's website or app using your username and password. Look for a section that says "Accounts," "Account Summary," "Account Details," or "My Accounts." Click into the checking account you need the number for.
The account number will usually appear near the top of the page, sometimes labeled as "Account Number" or "Checking Account." Some banks hide it behind a "View Details" button or require you to click a small eye icon to reveal the full number for security reasons. If you cannot find it in the obvious places, check the "Settings" or "Profile" section of your account.
Calling your bank directly
If you cannot locate your account number online or do not have checks available, 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 provide your account number over the phone. This method is slower than checking a check or logging in, but it is reliable and works during business hours. Some banks also allow you to retrieve your account number through their automated phone system by following the prompts.
What the numbers on a check actually mean
A check has three separate number groups at the bottom. From left to right: the routing number (nine digits), your account number (usually 10 to 12 digits), and the check number (the sequence number of that specific check). Do not confuse these. Your account number is always the middle group.
The routing number identifies your bank or credit union. The account number identifies your specific account within that bank. The check number is just a counter that increments with each check you write. When you need to provide your account number for a wire transfer, direct deposit setup, or automatic payment, you need only the middle group.
Why you need it and when to share it
Your account number is required to set up direct deposit from an employer, arrange automatic bill payments, receive wire transfers, or provide banking information to a payroll system. It is also needed when you contact your bank to troubleshoot a transaction or update your account.
Share your account number only with people and organizations you trust and who have a legitimate reason to use it. Your employer's payroll department, your bank, and a business you are sending a wire transfer to are safe recipients. Never provide it to someone who called you unsolicited, texted you a link, or emailed you asking for it. Legitimate banks and businesses will never ask for your account number via email or text.
If you cannot find your account number anywhere
If you have lost access to your online banking, do not have checks, and cannot reach customer service by phone, visit your bank in person with a photo ID. A teller can provide your account number immediately and can also print a statement showing it.
Some banks also send account statements by mail, and your account number appears on those statements. If you have an old statement, you can find it there. However, the fastest route is always a phone call to customer service or a visit to a branch.
Frequently Asked Questions
Is my account number the same as my debit card number?
No. Your debit card number is printed on the front of the card and is different from your account number. The account number is what you need for bank transfers and direct deposit. Your debit card number is for purchases and ATM withdrawals.
Can someone access my account if they know my account number?
Not without additional information. Your account number alone does not allow someone to withdraw money or make purchases. They would also need your routing number, PIN, online banking password, or other verification. Still, do not share it casually.
What if I see multiple account numbers in my online banking?
You may have more than one account at your bank — a checking account, a savings account, a money market account, and so on. Each has its own account number. Make sure you are looking at the correct account type for what you need to do.
Do I need both my routing number and account number for direct deposit?
Yes. Your employer's payroll system needs both numbers to deposit your paycheck into the correct account at the correct bank. Both appear on the bottom of a check, or you can get them from your bank's website or a customer service representative.
