The other area codes laid over 315
Area code 315 does not have Syracuse to itself. 1 other code — 680 — 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.
6801,762 blocks, 105 rate centres, mostly mobile
Each holds its own blocks and its own carrier mix, so a 315 number and a 680 number from the same street can report different line types. Filtering Syracuse by area code needs all 2 of them.
315 is not confined to Syracuse itself: its blocks sit across 149 rate centres, named in the table below.

Where 315 numbers are concentrated
NANPA truncates rate-centre names to ten characters and drops the spaces, which is why Baldwinsvl and Fayettevl are shortened. Names are reproduced as recorded rather than expanded — the abbreviation is the key the block data is filed under.

The largest holder, Verizon Wireless, has 13% of the code.
These are original allocations. A number keeps its digits and its block when its subscriber moves network, so a ported 315 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 315?
Area code 315 covers Syracuse, New York. It is not the only code there: 680 is an overlay on the same rate centres, so a Syracuse, New York number can start with any of them.
Is a 315 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 315 the split runs 34% mobile, 55% landline and 12% VoIP, so landline is the most likely single answer.
Which carriers hold 315 numbers?
The largest holders are Verizon Wireless, Onvoy, Bandwidth. That is the carrier the block was allocated to, which is not necessarily the network a given number sits on today.
How many 315 numbers are there?
The code holds 6,710 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 315 covers on the order of 6,710,000 possible numbers — most of which have never been issued to anyone.
