Account Number

A bank account number is a combination of numbers and letters that serves as a unique identifier for both the account and its holder.

What Is an Account Number? 

An account number is a string of numbers (and sometimes letters) that is used to identify a specific bank account and account holder. In this manner, financial institutions are able to give access to the account in a secure manner so that customers may send and receive payments.

When you create an account with a bank, the very first piece of information that is provided to you is a unique account number. Either a checking account or a savings account can serve this purpose. Every single form of banking transaction necessitates the use of an account number, regardless of whether the transaction takes place within the same branch or between two different financial institutions.

In the past, social security numbers were assigned to serve this purpose. However, the prevalence of their use led to an increase in instances of fraud and theft of identity. As a result, financial institutions have steadily distanced themselves from the practice. Even though social security numbers are still in use, account numbers are required in order to conduct banking transactions nowadays.

In today’s world, even though security precautions, such as multi-factor authentication, have helped reduce the number of instances of fraud and theft over the course of time, the numbers associated with bank accounts are still at risk of being stolen and put to harmful uses if account holders aren’t careful enough to engage in secure online banking practices.

What Is a Routing Number?

A nine-digit number that specifies the financial institution (bank or credit union) where an account is stored is referred to as the routing number. These numbers are also known as ABA routing numbers, which is a reference to the American Bankers Association, the organization responsible for assigning them. A routing number is proof that a financial institution is chartered at either the federal or state level and has an account with the Federal Reserve. This is a number that is exclusively used within the United States.

How to Find Your Bank Account Number and Routing Number?

You may locate your account and routing numbers: 

  1. At the bottom left-hand side of the check that is associated with your checking account

  2. By logging in to your online banking account, or 

  3. By asking a representative of the financial institution where you have your account.


Because the routing number associated with your financial institution is not linked solely to your account, it is possible that you can locate it online easily. If this is the case, you will need to ensure that the website you use is the one that is owned by your financial institution. It may be possible that other websites compile the routing number information for a number of different financial institutions in order to make things more convenient. However, it is preferable to obtain the number directly from the institution.

When you are ready to offer your bank’s routing and account numbers for a transaction involving your bank, double-check the information you obtained from your sources to ensure that the numbers are accurate. Even if you’re wrong by a single number, the transaction won’t go through successfully. In certain circumstances, you might be asked to input your account number twice before the system will accept it. This is done to ensure that the information is accurate and to reduce the likelihood of mistakes.
