Area code 914

In 1951, Long Island (Nassau and Suffolk counties) received area code 516 in a split of 914.

By the end of the 1990s, the increasing demand for cell phones and Internet dial-up connections caused concerns for exhaustion of the numbering pool.

In mitigation, numbering plan area 914 was reduced to Westchester County on June 5, 2000.

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.
