History

Creation: Area code 646 was put into service on July 1, 1999 and was the 262nd area code in service. It was one of 23 area codes introduced in 1999. It was the 10th area code in the state of New York. New York currently has 22 area codes. It was created to relieve the pressure on the 212 area code as the numbers in 212 were being exhausted.

Mnemonics: Prior to 1995, the middle digit of area codes was restricted to a 0 or 1 which do not correspond to a letter on a phone’s dialing pad. So, only area codes created in 1995 or later can have a mnemonic. The mnemonics for area code 646 include MGM, MGN, MGO, MHM, MHN, MHO, MIM, MIN, MIO, NGM, NGN, NGO, NHM, NHN, NHO, NIM, NIN, NIO, OGM, OGN, OGO, OHM, OHN, OHO, OIM, OIN, and OIO.
