Your account number is on your checks, your bank statement, or a call to your bank
The fastest way is to look at a check from your checking account — your account number appears at the bottom, usually after the routing number and before the check number. If you do not have checks, log into your online banking portal or mobile app and look for account details, account information, or a section labeled "accounts." Your account number will be listed there. If neither of those works, 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 the last four digits of your Social Security number — they will read your account number to you.
The account number itself is typically 8 to 12 digits long, though the exact length varies by bank. It identifies your specific account within that bank's system, separate from your routing number (which identifies the bank itself). You will need both numbers together to set up direct deposit, wire money, or receive a transfer from someone else.

Finding your account number through online banking
Log into your bank's website or open the mobile app and look for a section labeled "Accounts," "Account Details," "Account Information," or sometimes just "My Accounts." Most banks display your full account number right there on the main dashboard or in a dropdown menu. Some banks hide the full number for security and show only the last four digits by default — if that happens, look for a button or link that says "Show Full Account Number" or "Reveal Account Number," which may require you to enter your password again.
If you cannot find it in the obvious places, check under settings or profile information. Some banks organize account details under a "Statements" section or a "Documents" area. If you are still stuck, the help or FAQ section of your bank's website usually has a page titled something like "Where is my account number?" that walks you through the exact steps for that specific bank.
Reading your account number from a check
Look at the bottom left of any check. You will see three groups of numbers separated by colons or special symbols. The first group is your routing number (nine digits), the second group is your account number (usually 8 to 12 digits), and the third is the check number. The account number is always in the middle of these three groups.
If your checks are old or faded, the numbers may be hard to read. In that case, move to one of the other methods — online banking or a phone call to your bank. Do not guess at the number, because a wrong account number will send money to the wrong place or cause a transfer to fail.
Calling your bank to get your account number
Find the customer service phone number on the back of your debit card, on your most recent bank statement, or on your bank's website. Call during business hours and tell the representative you need your account number. They will ask you to verify your identity — usually your full name and the last four digits of your Social Security number, though some banks may ask for your date of birth or mother's maiden name as well.
Once you are verified, the representative will read your account number to you. Write it down or ask them to repeat it so you have it correct. This method works even if you have lost your checks or cannot access online banking, and it takes only a few minutes.
What to do if you cannot find your account number
If you have tried checks, online banking, and calling your bank and still do not have the number, the problem is usually that you are looking at the wrong account or the wrong bank. Double-check that you are logging into the correct bank's website and that you are looking at the right account if you have multiple accounts with that bank. Some people have a checking account and a savings account at the same bank, and each one has its own separate account number.
If you recently switched banks or closed an account, you may be looking for a number that no longer exists. In that case, you will need to contact your new bank or the old bank's customer service to clarify which account you actually need. If you have a very old account that you have not used in years, your bank may have closed it, and you will need to open a new account to get a new account number.
Account numbers for different types of accounts
Checking accounts, savings accounts, and money market accounts all have separate account numbers, even if they are at the same bank. If someone asks for your account number, make sure you give them the number for the correct account — sending a check deposit to your savings account number when they meant your checking account will delay the money reaching the right place. The same applies to transfers: if you are setting up direct deposit for your paycheck, use your checking account number unless your employer specifically asks for a different account.
If you have accounts at multiple banks, each account number is unique to that bank. Your account number at Bank A will not work at Bank B, even if the numbers happen to look similar. Always verify which bank the account belongs to before sharing the number with anyone.
Frequently Asked Questions
Is my account number the same as my routing number?
No. Your routing number identifies your bank (nine digits), while your account number identifies your specific account within that bank (usually 8 to 12 digits). You need both numbers together for direct deposit or wire transfers. They appear next to each other at the bottom of a check, with the routing number first.
Can I use my debit card number instead of my account number?
No. Your debit card number is different from your account number. Some systems may ask for one or the other, but they are not interchangeable. If someone asks for your account number, give them the account number, not your card number.
Is it safe to share my account number?
Your account number alone cannot be used to withdraw money from your account — a thief would also need your routing number and your bank's security procedures. It is safe to share your account number with your employer for direct deposit, with your bank for transfers, or with someone who is sending you money. Do not share it on unsecured websites or with people you do not trust.
What if my bank will not give me my account number?
Banks are required to provide you with your account number upon request. If a representative refuses, ask to speak to a supervisor or visit a branch in person. You can also file a complaint with your state's banking regulator or the Consumer Financial Protection Bureau if a bank continues to refuse.
