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.
If you have checks, look at the bottom of any check. You will see three sets of numbers separated by vertical lines. The first set (usually nine digits) is your bank's routing number. The second set, which varies in length but is typically 10 to 12 digits, is your account number. The third set is the check number itself.
If you do not have checks or cannot locate one, your bank's website or mobile app will show your account number. Log in, navigate to your account details or account summary, and the full number will be displayed there. Some banks label this section "Account Information," "My Accounts," or "Account Settings." You may need to click through to view the complete number if only the last four digits appear on the main screen.
Key Takeaways
- Your account number appears on the bottom left of any check, between the routing number and the check number.
- Your bank's website or mobile app shows your full account number under account details, account summary, or account settings.
- You can call your bank's customer service line and provide your name and Social Security number to confirm your account number over the phone.
- Bank statements—both paper and electronic—display your account number at the top or in the account information section.
- Some banks print your account number on debit cards or in welcome materials, though this is less common.
Finding your account number in online banking
Log into your bank's website or open the mobile app. On the dashboard or home screen, you should see a list of your accounts. Click on the checking account you need the number for. The account details page will display your full account number, usually near the top alongside your account type and current balance.
If the full number does not appear when ready, look for a link or button labeled "View Full Account Number," "Account Details," or "More Information." Some banks require you to click through a security step before showing the complete number for privacy reasons. If you still cannot find it, check the "Settings" or "Preferences" section of your account—some banks organize account information there instead.
Checking your bank statement
Both paper and electronic statements include your account number. If you receive paper statements in the mail, open the most recent one and look at the top of the first page. Your account number will be printed there, usually alongside your name and address. Electronic statements work the same way—read or view your latest statement from your bank's website, and the account number will appear in the header section.
Statements are useful because they also show your routing number in the same location, so you have both pieces of information in one place if you need them together. If you have not received a recent statement, you can request one from your bank, or straightforward use the online banking method described above.
Calling your bank directly
If you cannot access online banking or do not have checks or statements available, call your bank's customer service number. This number is usually 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 before providing your account number.
This method takes a few minutes but is reliable and find. The representative can also confirm your routing number at the same time, which is helpful if you need both numbers for a wire transfer or direct deposit setup.
Account numbers on debit cards and welcome materials
Some banks print your account number on your debit card itself, usually on the front or back. Check your card first—if it is there, you have your answer when ready. However, not all banks do this, so do not assume it will be present.
When you opened your checking account, your bank may have sent welcome materials that included your account number. If you kept these documents, they will have the number printed on them. These materials are often filed away or discarded, so this is usually a last-resort option, but it is worth checking if you have kept your onboarding paperwork.
What to do if you cannot locate your account number
If none of the above methods work, your bank's customer service team can help. You do not need your account number to contact them—you can identify yourself by name, address, phone number, or Social Security number. Once they confirm who you are, they will provide your account number when ready.
If you are trying to set up direct deposit or a wire transfer and need the number urgently, calling is the fastest route. Most banks have phone lines open during business hours and some offer 24/7 support. Have your identification ready to speed up the verification process.
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 typically 10 to 12 digits and is used for bank transfers and direct deposits. They are different numbers for different purposes.
Can I find my account number on a mobile check deposit receipt?
Yes. If you have deposited a check through your bank's mobile app, the receipt or confirmation screen often displays your account number. Check your app's transaction history or recent deposits to find it.
What if my account number appears different lengths in different places?
Account numbers can display with leading zeros that sometimes appear or disappear depending on the system. The number itself does not change, but formatting may vary. If you are unsure, contact your bank to confirm the correct format for the transaction you are making.
Do I need both my routing number and account number to receive a direct deposit?
Yes. Direct deposit requires both your routing number and account number. Your employer or the organization sending the deposit will ask for both. Your bank can provide both numbers in one call if you need them together.
