Area code 845
Area code 845 is a telephone area code in the North American Numbering Plan (NANP) for the U.S. state of New York. The numbering plan area comprises the mid- and lower Hudson Valley, specifically Orange, Putnam, Rockland, and Ulster counties, and parts of Columbia, Delaware, Dutchess, Greene, and Sullivan counties. The area code was created on June 5, 2000, by an area code split from most of the territory of area code 914, which was retained by Westchester County. Prior to October 2021, area code 845 had telephone numbers assigned for the central office code 988. In  2020, "988" was designated nationwide as a dialing code for the National Suicide Prevention Lifeline, which created a conflict for exchanges that permit seven-digit dialing. This area code was therefore scheduled to transition to ten-digit dialing by October 24, 2021. Service area. Numbering plan area 845 includes the following communities.
