Your bank account number appears on checks, online banking, and your bank statement
The easiest place to find your account number is a check from your checking account. Look at the bottom left of the check — you'll see three sets of numbers separated by colons or vertical lines. The middle set is your routing number, and the set on the right is your account number. The account number is typically 8 to 12 digits long, though this varies by bank.
If you don't have checks handy, log into your bank's website or mobile app. Most banks display your account number prominently on the dashboard or in an account details section. Some banks label it "Account Number," while others call it "Account ID" or simply list it under your account name. The exact location depends on your bank's interface, but it's usually one click away from your main account view.
Your bank statement — whether you receive it by mail or email — also shows your account number. Look near the top of the statement, usually next to your name and address. If you've lost access to your online account or don't have recent checks, you can call your bank's customer service line and provide your name, Social Security number, and other identifying information to confirm your account number over the phone.
Key Takeaways
- Your account number appears on the bottom right of any check from your checking account, after the routing number.
- Logging into your bank's website or app will show your account number in the account details or dashboard section.
- Bank statements — mailed or emailed — display your account number near the top, alongside your personal information.
- If you can't locate it through these methods, call your bank's customer service line with your identification information ready.
Finding your account number on different bank platforms
Online banks and traditional banks display account numbers in slightly different places. With online-only banks like Ally, Charles Schwab, or Discover, your account number typically appears on the main dashboard as soon as you log in, often labeled clearly in a box or card showing your account summary. These banks tend to make the number easy to find because they don't issue physical checks by default.
Traditional banks with physical branches — Bank of America, Wells Fargo, Chase, and others — usually hide the account number one level deeper. Log in, select the account you want, then look for a link or button labeled "Account Details," "Account Information," or "View Details." Some banks require you to click a small information icon next to your account name. The number will be displayed there alongside your routing number and other account details.
Credit unions work the same way as traditional banks. Log into your credit union's online portal, find your checking or savings account, and look for an account details or information section. If your credit union doesn't have online banking, visit a branch with your ID and ask a teller to provide your account number in writing.
What to do if you can't access your online account
If you've forgotten your password or lost access to your bank account online, you can still find your account number without logging in. 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 a form of ID ready. The representative will verify your identity and provide your account number over the phone.
Some banks also allow you to reset your password through their website without logging in. Look for a "Forgot Password" or "Can't Log In?" link on the login page. Follow the steps to reset your password using your email address or phone number, then log in and find your account number as described above.
If you have an older bank statement in your files, that's often the fastest route. Statements keep your account number on file for years, so even a statement from six months or a year ago will have the correct number. The account number doesn't change unless you close the account and open a new one.
Account numbers for different account types
Most people have a checking account, but if you hold a savings account, money market account, or other account type at the same bank, each one has its own account number. When you log into your bank's website, you'll see a list of all your accounts. Each account number is unique to that specific account, even though they all share the same routing number.
This matters when you're setting up direct deposit, wire transfers, or automatic payments. You need to use the account number for the specific account where you want the money to go. If you give your checking account number when you meant to use your savings account number, the deposit will go to the wrong place.
If you have accounts at multiple banks, each bank has a different routing number and each account has its own account number. Write them down or store them in a secure place if you use them regularly for transfers or direct deposit setup.
Keeping your account number safe
Your account number, combined with your routing number, is what someone needs to set up unauthorized transfers or payments from your account. While your account number alone isn't as sensitive as your Social Security number or PIN, you should still treat it as private information.
Don't share your account number with anyone who contacts you unsolicited — by phone, email, or text. Legitimate companies you do business with will already have your account number on file, and your bank will never ask you to confirm it via email or text. If someone claims 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 write checks, your account number is printed on them, so anyone who handles a check can see it. This is normal and unavoidable. The risk comes from sharing your account number with strangers or entering it on unsecured websites.
Account number vs. routing number: what's the difference
Your routing number identifies your bank or credit union. All customers at the same bank branch typically share the same routing number. Your account number identifies your specific account within that bank. Together, they form a complete address for your money.
Think of it like a mailing address: the routing number is the city and zip code, and the account number is your specific house number and street. When you set up direct deposit, you need both numbers. If you give the wrong routing number, the money might go to a different bank entirely. If you give the wrong account number, it goes to someone else's account at the same bank.
On a check, the routing number is the first set of numbers on the bottom left, and the account number is the second set. On your bank statement or online account, they're usually listed side by side in the account details section.
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 usually 8 to 12 digits and is not printed on your card. You can find your account number on checks, statements, or through online banking, but not on your debit card itself.
Can I find my account number on a mobile deposit receipt?
Yes. If you've deposited a check through your bank's mobile app, the receipt or confirmation screen often displays the last four digits of your account number. For the full account number, log into your online account or check a recent statement.
What if my bank doesn't issue checks?
Online banks and some newer financial institutions don't send checks. In that case, log into your online account to find your account number, or call customer service. Your account number is still there — you just won't see it printed on paper.
Do I need my account number to transfer money between my own accounts?
It depends on your bank. If both accounts are at the same bank and you're using online banking or a mobile app, you can usually select the accounts by name without entering the account number. If you're transferring between different banks, you'll need the account number and routing number of the receiving account.
Will my account number change if I close and reopen an account?
Yes. When you close an account and open a new one, you get a new account number. The old account number is retired and cannot be used. If you've set up automatic payments or direct deposit to the old account number, you'll need to update those with your new account number.
