The other area codes laid over 516
Area code 516 does not have Nassau County, New York to itself. 1 other code — 363 — serves 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.
363360 blocks, 11 rate centres, mostly VoIP

No carrier holds more than 11% of 516; the blocks are spread thin across many companies.
These are original allocations. A number keeps its digits and its block when its subscriber moves network, so a ported 516 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 516?
Area code 516 covers Nassau County, New York. It is not the only code there: 363 is an overlay on the same rate centres, so a Nassau County, New York number can start with any of them.
Is a 516 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 516 the split runs 41% mobile, 48% landline and 11% VoIP, so landline is the most likely single answer.
Which carriers hold 516 numbers?
The largest holders are Onvoy, Verizon Wireless, Omnipoint Communications, Inc.. That is the carrier the block was allocated to, which is not necessarily the network a given number sits on today.
How many 516 numbers are there?
The code holds 5,607 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 516 covers on the order of 5,607,000 possible numbers — most of which have never been issued to anyone.
