About Routing Transit Numbers
A routing transit number (RTN), routing number, or ABA number is a nine digit bank code, used in the United States, which appears on the bottom of negotiable instruments such as checks identifying the financial institution on which it was drawn. This code is also used by Federal Reserve Banks to process Fedwire funds transfers and by the Automated Clearing House to process direct deposits and other automated transfers. The routing number is derived from the bank's transit number originated by the American Bankers Association, which designed it in 1910.
Since 1911, the American Bankers Association has assigned transit numbers through a series of registrars, currently Accuity. The company is responsible for assigning new ABA numbers. Accuity publishes the ABA Number Directory in the American Bankers Association Key to Routing Numbers semi-annually.
There are approximately 28,000 active routing and transit numbers currently in use. Every financial institution in the United States has at least one of these.
