The ABA routing number was developed by the American Bankers Association in 1910. It identifies the specific financial institution responsible for the payment of a negotiable instrument.
Originally designed to identify only check processing endpoints, it has evolved to designate participants in automated clearinghouses, electronic funds transfer and online banking. The ABA routing number has changed over the years to accommodate the Federal Reserve System, the advent of MICR, and the implementation of the Expedited Funds Availability Act and Check 21.
Who Is Eligible for an ABA Routing Number?
An ABA Routing Number can be issued only to a federal or state chartered financial institution which has been determined to be eligible for a master account by a Federal Reserve Bank. The assignment of a routing number does not expand or change in any way the powers of the financial institution as specified in its charter. For more details, see the entire Routing Number Policy. Once in receipt of the assigned routing number, the financial institution must actually be granted the master account at one of the twelve Federal Reserve Banks in order to have direct access to the Federal Reserve’s payment systems and to settle transactions with other participants in the central banking system.

Where is the ABA routing number on my checks?
