Area code 518
Area code 518 is centred on Albany, New York. We hold 6,554 allocated blocks for it across 135 rate centres, split 33% mobile, 55% landline and 12% VoIP.
The other area codes laid over 518
Area code 518 does not have Albany to itself. 1 other code — 838 — 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.
8381,833 blocks, 107 rate centres, mostly VoIP
Each holds its own blocks and its own carrier mix, so a 518 number and a 838 number from the same street can report different line types. Filtering Albany by area code needs all 2 of them.
518 is not confined to Albany itself: its blocks sit across 135 rate centres, named in the table below.

Where 518 numbers are concentrated
NANPA truncates rate-centre names to ten characters and drops the spaces, which is why Saratogspg and Gloversvl are shortened. Names are reproduced as recorded rather than expanded — the abbreviation is the key the block data is filed under.

No carrier holds more than 11% of 518; 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 518 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 518?
Area code 518 covers Albany, New York. It is not the only code there: 838 is an overlay on the same rate centres, so a Albany, New York number can start with any of them.
Is a 518 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 518 the split runs 33% mobile, 55% landline and 12% VoIP, so landline is the most likely single answer.
Which carriers hold 518 numbers?
The largest holders are Verizon Wireless, Verizon New York, Inc., Onvoy. That is the carrier the block was allocated to, which is not necessarily the network a given number sits on today.
How many 518 numbers are there?
The code holds 6,554 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 518 covers on the order of 6,554,000 possible numbers — most of which have never been issued to anyone.
