The other area codes laid over 917
Area code 917 does not have New York City to itself. 6 other codes — 212, 332, 347, 646, 718, 929 — serve the same rate centres, laid over the same ground rather than dividing it. That is an overlay: a new code added when the old one ran out of numbers, covering the same streets. Two neighbours can hold different area codes, so the code says roughly when a number was issued rather than where it sits.
2122,202 blocks, 1 rate centre, mostly landline
3321,721 blocks, 1 rate centre, mostly mobile
3478,282 blocks, 13 rate centres, mostly mobile
6467,460 blocks, 1 rate centre, mostly mobile
7183,590 blocks, 13 rate centres, mostly landline
9297,731 blocks, 13 rate centres, mostly mobile
Each holds its own blocks and its own carrier mix, so a 917 number and a 212 number from the same street can report different line types. Filtering New York City by area code needs all 7 of them.

These are original allocations. A number keeps its digits and its block when its subscriber moves network, so a ported 917 number still reports the carrier it started with. Closing that gap needs a live query against the routing database. How line type is derived.

Common questions
Where is area code 917?
Area code 917 covers New York City. It is not the only code there: 212, 332, 347, 646, 718, 929 are overlays on the same rate centres, so a New York City number can start with any of them.
Is a 917 number a mobile or a landline?
It can be either, and the digits do not say which. North American mobile and landline numbers share the same ranges, so the answer comes from the carrier holding the block. In 917 the split runs 61% mobile, 29% landline and 10% VoIP, so mobile is the most likely single answer.
Which carriers hold 917 numbers?
The largest holders are Omnipoint Communications, Inc., T-Mobile USA, Inc., Verizon Wireless. That is the carrier the block was allocated to, which is not necessarily the network a given number sits on today.
How many 917 numbers are there?
The code holds 4,266 allocated blocks in our copy of the numbering plan. A block is 1,000 or 10,000 consecutive numbers depending on how deeply it has been pooled, so 917 covers on the order of 4,266,000 possible numbers — most of which have never been issued to anyone.
