How to Convert a Fractional Routing Number to a Nine-Digit Routing Number
A fractional routing number is a code that appears on some checks and deposit slips. It is used to identify the bank and branch where the account is located. The fractional routing number consists of two parts: a numerator and a denominator. The numerator contains the bank's symbol and the city or state where the bank is located. The denominator contains the Federal Reserve Bank's district and branch number.
To convert a fractional routing number to a nine-digit routing number, you need to use a routing number calculator, such as the one provided by Lane Guide. You can enter the fraction from the check or deposit slip, and the calculator will display the corresponding nine-digit routing number. You can also click the Locate Bank button to get more information about the bank and branch.
Here is an example of how to convert a fractional routing number to a nine-digit routing number:
The numerator is 12-3456, which means the bank's symbol is 12 and the city or state is 3456.
The denominator is 7890, which means the Federal Reserve Bank's district is 7 and the branch number is 890.
Enter the fraction into the routing number calculator and click Calculate.
The nine-digit routing number is 071089012.
Click Locate Bank to see that the bank name is ABC Bank and the branch address is 123 Main Street, Chicago, IL 60601.
Now you know how to convert a fractional routing number to a nine-digit routing number using a simple online tool. This can help you verify the bank and branch information for your transactions.Why do banks use fractional routing numbers? Fractional routing numbers are a legacy system that dates back to the early days of banking. Before the advent of electronic banking, checks and deposit slips had to be physically transported to the Federal Reserve Bank for processing. The fractional routing number helped sort and route the paper documents to the correct bank and branch. The numerator indicated the bank's symbol and location, while the denominator indicated the Federal Reserve Bank's district and branch. This way, the documents could be sorted by region and then by bank.
However, with the rise of electronic banking, fractional routing numbers became obsolete. The nine-digit routing number, also known as the ABA routing number or the transit number, became the standard way of identifying banks and branches in electronic transactions. The nine-digit routing number is assigned by the American Bankers Association (ABA) and consists of four parts: a four-digit Federal Reserve routing symbol, a four-digit institution identifier, and a one-digit check digit. The nine-digit routing number is unique for each bank and branch and can be found on the bottom left corner of checks and deposit slips.
Therefore, fractional routing numbers are no longer used for electronic transactions. They are only used for paper transactions or as a backup system in case the nine-digit routing number is not available. However, some banks still print fractional routing numbers on their checks and deposit slips for historical reasons or for customer convenience. In that case, you can use a routing number calculator to convert the fractional routing number to the nine-digit routing number. 0efd9a6b88
