Even though paper checks are not as ubiquitous today as they were in the past, the information that financial institutions need to facilitate a transaction between two accounts is the same, whether the transfer is initiated electronically or via check: a specific account number, along with a routing number and other information.

The account number is a unique identifier for your personal bank account. It tells the bank exactly which account to take money from and which one it goes to.

It is important to identify your account number before setting up electronic activity like online purchases, wire transfers or direct deposits. Failure to provide the correct account number could result in delayed or missing paychecks or payments on your monthly bills, such as rent, mortgages or student loans.

4 ways to find your account number

Find your account number on a check

Find your account number on a check

The easiest way to find your account number is to look at your checks. An account number typically is located at the bottom of a check. It’s the second group of numbers from the left, next to your nine-digit routing number. Banks have varying amounts of digits in the account numbers (as many as 12 digits) they assign to their customers.

Find it on your bank statement

If you don’t have a check, you may find your account number on your monthly bank statement. Look at the top of the document for a series of numbers labeled “account number.”

Find it through online banking

You also may look up your account number by signing into your online banking account via a mobile banking app or desktop computer.

If you have a savings account and a checking account at the same bank, you likely will have two different account numbers — one for each account. It’s important to know which account you intend to use for a given transaction before looking for the account number.

Make sure that you have a secure internet access when accessing financial information like this. It is never a great idea to conduct online banking via Wi-Fi at a coffee shop!

Call your bank

If you still can’t find your account number, call your bank’s customer service department, or visit a local branch to ask for help in looking up your bank account.
