347 Area Code: New York City, New York

The 347 area code is one of several area codes serving New York City, layered onto the same five-borough footprint long served by 212, 718, and 917. The 347 designation has been filling with allocations since the late 1990s, when the city's number demand began outpacing what the older codes alone could support. New York City itself sits at the mouth of the Hudson, organized across five boroughs that span Manhattan's narrow island, the western end of Long Island (Brooklyn and Queens), the Bronx mainland, and Staten Island in the harbor.

Records linked to 347 numbers in the directory often include other New York cities — Albany, Binghamton, Brentwood, and Buffalo among them. None of those are inside the 347 footprint. The pattern reflects standard public-record dynamics, with phone numbers porting across New York and addresses linked across multiple cities. The directory currently documents 725 distinct prefixes within 347 in detail, a working subset of the prefix population the code carries.

New York City's population dominates the demographic story: the city sits among the largest in the world, with the metropolitan area many times its city-level size. Home values in the city run several times the US median, household income comes in slightly above the national reading citywide (with sharp variation by borough and neighborhood), and the median age sits close to the US figure. The 347 footprint shares those demographics with the city's other overlay codes because they all serve the same broad geography in overlapping form.
