Your checking account number is printed on the bottom left of your checks, in your online banking portal, or by calling your bank
The account number is a string of digits unique to your checking account — usually between 8 and 12 numbers long. It identifies your specific account at your bank, separate from your routing number (which identifies the bank itself). You will need both numbers together to set up direct deposit, arrange wire transfers, or give someone permission to withdraw money from your account.
The fastest way to find it depends on what you have access to right now. If you have a checkbook, look at the bottom of any check. If you use online banking, log in to your account dashboard. If neither of those works, a quick call to your bank's customer service line will get you the number in under a minute.
Key Takeaways
- Your account number appears on the bottom left of your checks, printed 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 viewing your account details.
- Calling your bank's customer service number on the back of your debit card will connect you to someone who can read your account number to you over the phone.
- Some banks print the account number on your monthly statement or on the debit card itself, though placement varies by bank.
- Never share your full account number with someone unless you trust them completely and know exactly what they will use it for.
Reading your check to find the account number
If you have checks from your account, the account number is printed on the bottom of every check. Look at the bottom edge — you will see a series of numbers separated by colons or spaces. The first set of numbers is your routing number (nine digits). The second set, usually longer, is your account number.
The order is always: routing number, then account number, then check number. For example, the bottom might read 121000248 : 1234567890 : 0001. In this example, 121000248 is the routing number, 1234567890 is the account number, and 0001 is the check number.
If you do not have checks or cannot read the print clearly, move to one of the other methods below. Do not guess or try to reconstruct the number from memory — you need the exact digits.
Finding it through online banking or your mobile app
Log into your bank's website or open the mobile app on your phone. 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.
Some banks show the full account number right away. Others hide most of the digits for security and show only the last four numbers on the main screen — you may need to click "View Full Account Number" or a similar button to see all the digits. If you cannot find it after looking through the account details section, try searching the app or website for "account number" using the search or help function.
This method is often the fastest if you already use online banking regularly, because you do not have to wait on hold or dig through papers.
Calling your bank directly
Pick up the phone and call the customer service number on the back of your debit card, or search online for your bank's main customer service line. When you reach someone, tell them you need your checking account number. They will ask you to verify your identity — usually by providing your name, date of birth, and the last four digits of your Social Security number or a PIN you set up when you opened the account.
Once you are verified, the representative will read your account number to you. Write it down carefully as they say it, or ask them to repeat it so you can confirm you have it right. This method works even if you have lost your checks or do not use online banking.
Checking your monthly statement
If your bank sends you a paper statement in the mail, your account number is usually printed near the top of the first page, often next to your name or account type. If you receive statements by email, open the PDF and look in the same place.
Statements are typically sent once a month, so this method only works if you have a recent one on hand. If you need the number right away, one of the other methods will be faster.
Looking at your debit card
Some banks print your account number on the front or back of your debit card, though not all do. If your bank does, it will be a series of digits separate from the card number itself. The card number (the long number on the front) is different from your account number — do not confuse the two.
Check both sides of your card carefully. If you do not see an account number printed there, your bank may not include it on the card, and you will need to use one of the other methods above.
What to do if you cannot find your account number
If you have tried the methods above and still cannot locate it, call your bank. This is the safest option when you are stuck, because a real person can verify who you are and give you the correct number. You do not need to have anything in front of you — just your identity information and a few minutes on the phone.
Do not try to guess your account number or use a number you think might be right. Banks need the exact digits, and using the wrong number can send money to the wrong account or cause a transaction to fail.
Frequently Asked Questions
Is my account number the same as my card number?
No. Your card number is the 16-digit number printed on the front of your debit or credit card. Your account number is a separate set of digits that identifies your checking or savings account at the bank. You need the account number for things like direct deposit or wire transfers, not the card number.
Can someone take money from my account if they know my account number?
They would also need your routing number and, in most cases, your permission or access to your online banking login. Knowing only the account number is not enough to drain an account, but it is still information you should not share casually. Only give it to people and organizations you trust completely.
Why do I need both a routing number and an account number?
The routing number tells the banking system which bank to send money to. The account number tells that bank which specific account within the bank should receive the money. Together, they may support money goes to the right place. Without both, a transfer cannot be completed.
What if the numbers on my check are smudged or hard to read?
Use online banking or call your bank instead. Do not try to guess or fill in missing digits — banks need the exact numbers. A phone call to customer service takes just a few minutes and guarantees you have the right information.
Do I need my account number to use my debit card at a store?
No. You only need your card number, expiration date, and CVV (the three-digit code on the back) to make purchases. Your account number is for banking transactions like direct deposit, wire transfers, or setting up automatic bill payments.
