Area code 917, Telephone prefix in New York City, United States.
Area code 917 is a telephone prefix covering all five boroughs of New York City: Manhattan, Brooklyn, Queens, the Bronx, and Staten Island. This code operates as an overlay area without geographic boundaries, meaning it can be assigned anywhere within the city limits.
The prefix was introduced in 1992 to meet the growing demand for mobile phone numbers in the city. It became the first overlay code in the North American Numbering Plan, changing the earlier practice of geographically separate area codes.
Many residents associate the 917 prefix with the early mobile phone era in the city and see it as a symbol of digital connection. Those who hold this number often signal a long-standing tie to the metropolis, giving it special meaning in daily life.
Dialing a phone number with this prefix reaches connections throughout the city, regardless of borough. New numbers with 917 continue to be issued by mobile and landline providers when local numbers are available.
Even though newer area codes such as 646 and 332 were added in the city, 917 remains recognized as the original mobile phone prefix. Some residents hold onto their old numbers because they are linked to the early days of mobile communication.
