What is an ABA Routing Number?
An ABA routing number, also known as a routing transit number (RTN), is a nine-digit code used by financial institutions in the United States to identify the specific bank or credit union involved in a transaction. This number ensures that funds are directed to the correct institution, whether for wire transfers, direct deposits, or check processing.
ABA routing numbers are essential for domestic transactions within the U.S. and are used by both individuals and businesses. Each financial institution has its unique routing number, which is assigned based on its location and membership in the American Bankers Association (ABA).
For example, if you're setting up a direct deposit for your salary, your employer will require your bank account number and ABA routing number to ensure the funds are deposited into the correct account.
History of ABA Routing Numbers

The ABA routing number system was first introduced in 1910 by the American Bankers Association to standardize check processing. Initially designed to simplify the manual sorting of checks, the system has evolved to accommodate modern electronic banking transactions.
Today, ABA routing numbers are managed by Accuity, a global provider of regulatory and financial data solutions. Accuity ensures the accuracy and integrity of routing numbers, updating them regularly to reflect changes in the banking landscape.
