with a date of change for each bank for your reference.
A bank
routing number, or ABA number is a nine digit bank routing number
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 Federal wire
fund transfers and by the Automated Clearing House (ACH) to process
direct deposits and other automated bank wire transfers. The bank
routing number is derived from the bank's transit number originated
by the American Bankers Association (ABA), which designed it in
the year 1910.
Since
1911, the American Bankers Association has assigned bank routing
numbers through a series of registrars, currently Accuity. Accuity
is responsible for assigning new ABA numbers. Accuity publishes
the ABA Number Directory in the American Bankers Association Key
to Bank Routing Numbers semi-annually.
There
are over 22,000 active bank routing and transit numbers currently
in our ACH database. Every financial institution in the United States
of America has at least one of these bank routing numbers.
