ABA is a trade association for the U.S. banking industry, established in 1875. It represents banks of all sizes, providing professional development and setting industry standards.
An ABA routing number is a nine-digit code used to identify financial institutions in the U.S.  Developed by the ABA, this number is used to transfer money domestically when processing various transactions (e.g. checks, direct deposits), to ensure that funds are sent to the right account. 
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
