Your checking account number is printed on the bottom left of your checks, in your bank's online portal, or by calling your bank's customer service line
The easiest place to look is the bottom of any check you have. The account number appears after the routing number and before the check number — it's typically 8 to 12 digits long. If you don't have checks handy, log into your bank's website or mobile app; your account number is usually visible on the account summary page or in account settings. If you can't access online banking, call the customer service number on the back of your debit card or on your bank's website, and a representative can read it to you over the phone.
You'll need your account number when setting up direct deposit, making wire transfers, paying bills online, or providing banking information to employers and government agencies. Having it readily available saves time and reduces the chance of errors when entering it into forms or payment systems.

Finding your account number on a check
Look at the bottom of any check. You'll see a series of numbers printed in magnetic ink. Reading from left to right, the first set of numbers is your bank's routing number (usually 9 digits), the second set is your account number, and the third set is the check number itself.
The account number is the longest of the three and typically ranges from 8 to 12 digits depending on your bank. Some banks print it more clearly than others, but it's always in that same position on every check you have from that account. If the print is faded or hard to read, you can use your bank's online tools or call customer service instead.
Locating your account number online
Log into your bank's website or open the mobile app on your phone. Most banks display your account number prominently on the main account page or dashboard. Look for a section labeled "Account Summary," "Account Details," or "Account Information."
Some banks hide the full account number for security reasons and show only the last four digits on the main page. If that's the case, click into "Account Settings," "Full Account Details," or a similar option to view the complete number. You may need to verify your identity with a password or security question before the full number is displayed.
Getting your account number by phone
Call the customer service number printed on the back of your debit card or visit your bank's website to find the main customer service line. Have your Social Security number and a form of identification ready when you call.
Tell the representative you need your checking account number. They will verify your identity and read the number to you. Write it down carefully as they say it, or ask them to repeat it so you can confirm each digit. Some banks also allow you to access account information through their automated phone system by entering your PIN or Social Security number.
What to do if you can't find your account number
If you've checked your checks, your online banking portal, and called customer service without success, contact your bank in person at a local branch. Bring a government-issued ID and your debit card. A teller can print out your account information or write down your account number for you on the spot.
If you've recently opened your account and haven't received checks yet, your bank may have sent your account number in a welcome letter or email. Check your email inbox and spam folder for messages from your bank. The account number is often included in the subject line or in the body of the letter.
Keeping your account number safe
Your account number, combined with your routing number, is enough information for someone to set up unauthorized transfers or payments from your account. Don't share it with anyone you don't trust, and be cautious when entering it into unfamiliar websites or forms.
When you need to provide your account number to a business or government agency, verify that you're using an official website or phone number first. Scammers sometimes create fake payment pages or call pretending to be from legitimate organizations. If you're unsure whether a request is real, hang up and call the organization directly using a number you find independently.
Account numbers for different account types
If you have multiple accounts at the same bank — such as a checking account, savings account, and money market account — each one has its own unique account number. The routing number stays the same across all your accounts at that bank, but the account number changes for each account.
When setting up direct deposit or making transfers, make sure you're using the correct account number for the account you want the money to go into. Using the wrong account number will send the funds to the wrong place, and you'll need to contact your bank to correct the error.
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 your card and is different from your account number. Your account number is what's printed on your checks and in your online banking portal. You need the account number for direct deposit and wire transfers, not the debit card number.
Can I use my account number to make purchases online?
No. Your account number is for bank-to-bank transfers and direct deposit, not for online shopping. When you buy something online, you use your debit card number, expiration date, and CVV code — not your account number. Giving your account number to a merchant for a purchase is not safe.
What if I see my account number on a receipt or document I lost?
Contact your bank immediately. Some businesses print partial account numbers on receipts for your records, but if you've lost a document with your full account number visible, let your bank know so they can monitor the account for suspicious activity. You don't need to close the account unless your bank recommends it.
Do I need both my routing number and account number for direct deposit?
Yes. Your employer or the organization setting up direct deposit will ask for both numbers. The routing number tells the system which bank to send the money to, and the account number tells it which specific account within that bank. Both are required for the transfer to work correctly.
Can I change my account number?
Most banks do not allow you to change your account number. If you're concerned about your account number being compromised, contact your bank to discuss your options. In rare cases, your bank may close your current account and open a new one with a different number, but this is not a standard service and may take time to set up.
