Editing Area codes 716 and 624 (section)

==History==
When the [[American Telephone and Telegraph Company]] (AT&T) devised the first nationwide [[telephone numbering plan]] for [[Operator Toll Dialing]] in the 1940s, New York state was initially divided into five numbering plan areas, the most of any state, assigning a distinct area code to each. In 1947, area code 716 was assigned to an area with a significant portion of [[Central New York]], as far east as [[Corning, New York|Corning]].

In 1954, the numbering plan area was reduced in size by merging its eastern portion with the southern portion of [[area code 315|NPA 315]], to create [[area code 607]].<ref>{{cite web

In 2001, the new [[area code 585]] was created for Rochester and its suburbs. Until 1993, it was bounded at the [[Niagara River]] by [[area code 416]] (now [[area codes 905, 289 and 365|905]]) in [[Ontario]].

Prior to October 2021, area code 716 had telephone numbers assigned for the [[central office code]] 988. In 2020, ''988'' had been 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.<ref name="pl556">{{cite web

A 2022 analysis by the NANP Administrator determined that area code 716 will exhaust its central office prefixes in 2024.<ref name="exhaust">{{cite web|url=https://nationalnanpa.com/reports/2022-1_NPA%20Exhaust_Projections.pdf|date=April 21, 2022|publisher=North American Numbering Plan Administrator |title=2022-1 NRUF and NPA Exhaust Analysis|access-date=April 24, 2022}}</ref> As a result, [[New York Public Service Commission]] approved area code 624, and was assigned to form an all-service [[overlay complex]] in the 716 area, with an in-service date of November 16, 2023.<ref name="npa624overlay">{{cite web
