Are you familiar with bank routing numbers? These numbers are used to identify the financial institution where an account is held. They are necessary for various financial transactions, such as direct deposits and wire transfers. However, did you know that there is a check digit calculator that can help ensure that the routing number you are using is valid? In this article, we will discuss what a bank routing number check digit calculator is and how to use it.
What is a Bank Routing Number Check Digit Calculator?
A bank routing number check digit calculator is a tool that helps determine the validity of a routing number. It is a formula that uses the routing number to generate a check digit. This check digit is then compared to the actual check digit in the routing number. If the two digits match, the routing number is considered valid.
Why is a Bank Routing Number Check Digit Calculator Important?
Using an invalid routing number can result in significant problems. For example, a direct deposit may be rejected, or a wire transfer may be sent to the wrong financial institution. This can cause delays, additional fees, and other issues. A bank routing number check digit calculator can help prevent these problems by ensuring that the routing number being used is valid.
How to Use a Bank Routing Number Check Digit Calculator
Using a bank routing number check digit calculator is easy. All you need is the routing number you want to check. Simply enter the routing number into the calculator, and it will generate the check digit. You can then compare the check digit to the check digit in the routing number to ensure that they match.
Example of Using a Bank Routing Number Check Digit Calculator
Let’s say you have a routing number of 123456789. You can use a bank routing number check digit calculator to generate the check digit. The formula used to generate the check digit is as follows:
1 x 3 + 2 x 7 + 3 x 1 + 4 x 3 + 5 x 7 + 6 x 1 + 7 x 3 + 8 x 7 + 9 x 1 = 209
The next step is to divide the total by 10 and take the remainder:
209 / 10 = 20 remainder 9
The check digit is the difference between 10 and the remainder:
10 – 9 = 1
The complete routing number, including the check digit, is 1234567891.
