Westchester County, New York shares the 914 area code — one of the original 86 area codes assigned when the North American Numbering Plan launched on January 1, 1947. Back then, 914 covered ten counties across the entire Hudson Valley and Long Island. Today, after two splits, it covers just one: Westchester.
This guide covers 914's cities and coverage, the two splits that shrank its territory from ten counties to one, what's driving demand across this corporate-and-commuter corridor, and how to dial correctly.
Coverage at a glance
914 covers all of Westchester County — White Plains, Yonkers, New Rochelle, Mount Vernon, Peekskill, Rye, and Tarrytown among its cities and towns — with small overlapping pockets in neighboring Putnam and Rockland counties.
Ten counties down to one
1947 — 914 launched as one of North America's original area codes, covering ten counties: Westchester, Putnam, Rockland, Orange, Dutchess, Ulster, Sullivan, Delaware, Nassau, and Suffolk.
1951 — 516 split off to cover Nassau and Suffolk counties on Long Island.
2000 — 845 split off to cover the rest of the Hudson Valley — Dutchess, Orange, Putnam, Rockland, Sullivan, and Ulster — leaving 914 with just Westchester County, the footprint it holds today.
What's driving demand across Westchester County
Westchester's economy has shifted from a historic tech corridor into finance, biotech, and a deep commuter base:
Corporate headquarters Mastercard and PepsiCo both anchor global headquarters in Westchester, alongside a long-standing IBM presence that shaped the county's identity for decades.
Biotech and pharma Regeneron Pharmaceuticals anchors a large research and administrative workforce in Greenburgh, part of a growing biotech cluster.
NYC commuter base Fast rail access into Manhattan makes Westchester one of the wealthiest and most in-demand suburban corridors in the country.
Many of these Westchester businesses are moving their phone systems onto UCaaS (Unified Communications as a Service) — one cloud platform for calling, video, and messaging that scales as a company adds offices across the county, the same pattern behind other original-1947 codes like 910 in North Carolina.

Features worth adding on a 914 number
