Your checking account number is printed on the bottom left of your checks, in the second set of numbers after the routing number
The easiest place to find it is the bottom of any check you have. Look at the numbers printed along the bottom edge. You will see three separate groups of numbers. The first group (usually nine digits) is your routing number. The second group is your account number, which is typically 10 to 12 digits long. The third group is the check number itself.
If you do not have checks in front of you, your bank's website, mobile app, or a phone call to customer service will show you the number in seconds. Many people find the online method faster because they do not have to locate a checkbook.
Key Takeaways
- Your account number appears on the bottom left of any check, after the routing number and before the check number.
- You can find your account number by logging into your bank's website or mobile app and looking at your account details.
- Calling your bank's customer service line and providing your name and identifying information will get you the number over the phone.
- Some banks print the account number on your debit card or in your welcome paperwork, though not all do.
- Never share your account number with anyone unless you initiated the transaction and trust the recipient.
Finding it online through your bank's website or app
Log into your bank's website or open the mobile app. Look for a section labeled "Account Details," "Account Information," or "My Accounts." Your account number will be displayed there, usually alongside your routing number and current balance.
Most banks show the full account number on this screen, though some mask it for security and only display the last four digits. If you see only partial numbers, click on the account name or an "expand" option to reveal the full number. The page may also let you copy the number directly, which is useful if you need to paste it into a form.
Calling your bank to get the number by phone
Call the customer service number on the back of your debit card or on your bank's website. Tell the representative you need your checking account number. They will ask you to verify your identity—usually your full name, date of birth, and the last four digits of your Social Security number or a PIN you set up.
Once verified, they will read your account number to you. Write it down or ask them to repeat it. This process typically takes two to three minutes. If you are calling during business hours, you will usually reach a person when ready; after-hours calls may route to an automated system that can also provide the number.
Checking your debit card or bank statements
Some banks print your account number on your debit card, usually on the front or back. Check both sides. Not all banks do this—many print only the card number for security reasons—so do not be surprised if it is not there.
Your account number may also appear on paper statements or in your online statement history. If you receive paper statements in the mail, look at the top right corner or the header section. Digital statements usually show it near the account summary. This is slower than checking a check or logging in, but it works if you have statements saved.
What to do if you cannot locate it
If you have no checks, cannot access your online account, and do not have your debit card handy, the fastest option is a phone call. You do not need to know your account number to call—the bank can look it up using your name and Social Security number.
If you are locked out of your online account, use the "Forgot Password" or "Unlock Account" option on your bank's login page, or call the number on your debit card. Do not email your bank asking for your account number; banks will not send sensitive information by email for security reasons.
Why you need it and when to share it safely
Your account number is required for direct deposits (like paychecks or tax refunds), wire transfers, setting up automatic bill payments, and when you need to provide banking details to an employer or government agency. It is not secret information in the way a password is—your checks have it printed on them—but you should still treat it with care.
Share your account number only when you have initiated the transaction and you trust the recipient. If someone calls you asking for your account number, do not give it to them. Legitimate businesses and government agencies will not call and ask for it unprompted. If you are unsure, hang up and call the organization back using a number you find yourself, not one they provide.
Frequently Asked Questions
Is my account number the same as my card number?
No. Your card number is the 16 digits printed on the front of your debit or credit card. Your account number is a separate number that appears on your checks and in your bank account details. They are linked to the same account, but they are different numbers.
Can someone access my account if they have my account number?
They cannot log in or withdraw money with only your account number. However, they could potentially set up unauthorized transfers or payments if they also have your routing number. This is why you should not share both numbers together with someone you do not trust. If you think your account number has been compromised, contact your bank when ready.
What if my bank does not show the full account number online?
Some banks mask the full number for security and show only the last four digits. Call customer service or look at a physical check. If you have neither, a phone call to your bank is the quickest way to get the full number verified and read to you.
Do I need my account number to set up direct deposit?
Yes. Your employer or the organization sending the deposit will ask for both your routing number and account number. You can provide these from a check, your online account, or by calling your bank. Make sure you give them the correct numbers—a mistake will send the deposit to the wrong account.
