Area code 646
Area code 646 covers New York City, New York. We hold 7,460 allocated blocks for it across 1 rate centre, split 49% mobile, 44% landline and 7% VoIP.
The other area codes laid over 646
Area code 646 does not have New York City to itself. 3 other codes — 212, 332, 917 — 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
9174,266 blocks, 14 rate centres, mostly mobile
Each holds its own blocks and its own carrier mix, so a 646 number and a 212 number from the same street can report different line types. Filtering New York City by area code needs all 4 of them.
New York is split across 21 area codes — 347, 929, 646, 845, 315, 518 and others. By allocated blocks 646 is the third largest of them, holding 8% of the New York total.

Common questions
Where is area code 646?
Area code 646 covers New York City, New York. It is not the only code there: 212, 332, 917 are overlays on the same rate centres, so a New York City, New York number can start with any of them.
Is a 646 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 646 the split runs 49% mobile, 44% landline and 7% VoIP, so mobile is the most likely single answer.
Which carriers hold 646 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 646 numbers are there?
The code holds 7,460 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 646 covers on the order of 7,460,000 possible numbers — most of which have never been issued to anyone.
