Your account number is printed on the bottom left of your checks, in your online banking portal, or by calling your bank
The easiest place to find your account number depends on what you have access to right now. If you have a checkbook, look at the bottom of any check — your account number is the middle set of digits, usually 10 to 12 numbers long. If you bank online or have a mobile app, log in and look for "Account Details," "Account Information," or a similar tab; your account number will be listed there. If you have neither, call your bank's customer service line (the number is on your debit card or on your bank's website) and give them your name and identifying information — they will read it to you over the phone.
You need your account number when you set up direct deposit for tax refunds, receive insurance payouts, or authorize automatic payments. Banks keep account numbers on file in multiple places so you can retrieve it without visiting a branch.
Key Takeaways
- Your account number appears on the bottom of your checks as the middle string of digits between the routing number and the check number.
- Online banking portals and mobile apps display your account number under account details or account information sections.
- Calling your bank's customer service line will get you your account number within minutes if you cannot access it any other way.
- Some banks print your account number on your debit card, though not all do — check the back or front of your card.
- Your account number is different from your routing number; you often need both for direct deposit and wire transfers.
Finding your account number on a check
The bottom of a check contains three separate numbers in this order: routing number, account number, check number. Your account number is always in the middle. It is typically 10 to 12 digits long, though the exact length varies by bank. You do not need a blank check — any check from your account will show the same account number.
If you have not ordered checks yet or your checkbook is at home, this method will not work immediately. But if you have even one check lying around, you have your answer.
Checking your online banking account
Log into your bank's website or open their mobile app. Look for a section labeled "Accounts," "Account Details," "Account Information," or "My Accounts." Your account number will be displayed there, usually near your account balance and recent transactions. Some banks show it prominently on the main dashboard; others require you to click into a specific account to see it.
If you cannot find it in the obvious places, use the search function in your app or website (usually a magnifying glass icon) and search for "account number." Most banks will direct you to the right page. You can also look for a "Help" or "FAQ" section that explains where account information is located.
Calling your bank directly
Pick up the phone and call the customer service number on the back of your debit card or on your bank's website. Tell the representative you need your 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 recent transaction amount. Once verified, they will read your account number to you.
This method takes five to ten minutes and works even if you do not have online access or checks. Bank customer service lines are open during business hours and sometimes 24/7, depending on your bank. If you call outside business hours, you may reach an automated system that cannot help, so try again during the day or use online banking instead.
Checking your debit card
Some banks print your account number on your debit card itself. Look at both the front and back of the card. If it is there, it will be a separate number from the card number (which is the long number on the front). Not all banks do this, so do not be surprised if your account number does not appear on your card — it just means you will need to use one of the other methods.
Your debit card number and your account number are not the same thing. You need your account number for direct deposit and bank transfers, not your card number.
Account number vs. routing number: what is the difference
Your account number identifies your specific account at your bank. Your routing number identifies the bank itself. When you set up direct deposit for a tax refund or receive a wire transfer, you usually need both numbers. The routing number tells the sending bank which institution to send the money to; the account number tells that institution which account within the bank should receive it.
On a check, the routing number comes first (on the left), and the account number comes second (in the middle). If you are filling out a form and it asks for both, do not mix them up — entering the wrong number will send money to the wrong place or cause the transaction to fail.
What to do if you cannot find your account number
If you have tried online banking, checked your checks, and cannot reach your bank by phone, visit a branch in person. Bring a photo ID and ask a teller for your account number. They can print it out for you or write it down on the spot. This is the slowest option but works when everything else is unavailable.
If you are waiting for a refund and need your account number urgently, prioritize calling your bank during business hours. Most customer service representatives can retrieve it within a minute or two once you are verified.
Frequently Asked Questions
Is my account number the same as my debit card number?
No. Your debit card number is the long number printed on the front of your card. Your account number is a separate number that identifies your account at the bank. You need your account number for direct deposit and transfers, not your card number.
Can someone steal money from my account if they know my account number?
Your account number alone is not enough to steal money. A person would also need your routing number and usually additional verification like your name or Social Security number. Do not share your account number with people you do not trust, but knowing it is not an immediate security risk.
What if my bank closed and I cannot find my old account number?
Contact the Federal Deposit Insurance Corporation (FDIC) if your bank failed, or reach out to the bank that acquired your old bank's accounts. They can look up your old account number using your name and Social Security number. If you have old checks or statements, those will also show the number.
Do I need my account number to check my balance?
No. You can check your balance by logging into online banking with your username and password, calling your bank's automated phone line, or visiting an ATM with your debit card. Your account number is mainly needed for setting up direct deposit, wire transfers, and authorizing payments.
Will my account number change if I switch banks?
Yes. When you open an account at a new bank, you get a new account number. Your old account number stays with your old bank. If you are moving money or setting up direct deposit at a new bank, use the new account number, not the old one.
