New York City, New York · EST/EDT (UTC-5) · United States
All five NYC boroughs — primarily cell phones and pagers
Introduced in 1992 as the first US area code exclusively assigned to mobile phones and pagers — before 917, all cell numbers used geographic codes. Now covers all five NYC boroughs alongside 212, 646, 718, 929, and 347. A 917 number is widely recognised as a Manhattan or NYC-based mobile contact. High scam-call awareness due to NYC's density.
Dial 1 + 917 + 7-digit number for calls from outside the area. Local calls within the same area code may use 7-digit dialing where available.
From outside United States: dial your country's exit code + 1 + 917 + number. From most countries, the format is +1-917-XXX-XXXX.
Area code 917 is in EST/EDT (UTC-5). Business hours are typically 9:00 AM – 5:00 PM local time. Remember that clocks shift during DST (March–November).
While (917) is a legitimate area code, scammers can spoof any number. Never share personal info with unknown callers. Verify by calling the organization directly.
