What is an ABA Number?
An ABA number, also known as a routing transit number (RTN), is a nine-digit code assigned to financial institutions in the United States. This number identifies the specific bank or credit union involved in a financial transaction. It ensures that funds are routed to the correct institution, making it an essential component of the banking system.
ABA numbers were introduced by the American Bankers Association (ABA) in 1910 to streamline check processing. Today, they are used for various electronic transactions, including direct deposits, wire transfers, and automated clearing house (ACH) payments.

By providing a standardized method of identifying financial institutions, ABA numbers help prevent errors and fraud in the banking system.
History of ABA Numbers
The concept of ABA numbers dates back to 1910 when the American Bankers Association developed the routing transit number system. Initially, these numbers were used to facilitate check processing.
