Find any 646- phone number in New York

The 646 area code is a telephone numbering plan code in the North American Numbering Plan. The code serves parts of the boroughs of Manhattan, Brooklyn, Queens and the Bronx in New York City. The 646 area code began use in the summer of 1999 and replaced the 212 area code. The area code is the location where a telephone number is assigned, and the numbers assigned within that particular area code are what are used to distinguish the callers.

Area codes are chosen by a system known as the North American Numbering Plan (NANP). This system is in use by the United States, Canada, and a number of Caribbean nations. The NANP assigns each geographic area with a three-digit area code and seven-digit local telephone numbers. The assignment of area codes is based on population trends, wiring configurations and traffic volume. As population grows and an area code becomes congested with too many telephone numbers, the area code is split into two or more distinct parts and new area codes are created. This is the case with the 646 area code, as it was created when the 212 area code become overcrowded.
