What Area Code Is 347?
Updated General Knowledge
Why it exists: 718 numbers started running out in the late 1990s. 347 was introduced in 1999 so new lines could get a 347 number in the same neighborhoods instead of splitting Brooklyn or Queens onto a new map. You must dial 10 digits (area code + number) even for local calls in these overlays.
What 347 is not:
- Not a different state or a suburb belt like 516 (Long Island) or 914 (Westchester) as its primary identity — 347 numbers are NYC.
- Not only "cell phones." Overlays assign new numbers of any type (mobile, VoIP, landline) once the original code is exhausted. 917 is the one historically associated with NYC mobiles, but 347 shows up on all kinds of lines now.
Nearby NYC codes, for orientation
| Code | Role |
|---|---|
| 212 / 646 / 332 | Manhattan overlays |
| 718 / 347 / 929 | Outer boroughs (718 original; 347 and 929 later overlays) |
| 917 | Citywide overlay, lots of mobiles |
A 347 caller ID usually means the number was issued in the NYC numbering plan, not that the person is standing in a specific borough at that moment (number portability moves lines around).
