Area code 339 is centred on Massachusetts. We hold 1,113 allocated blocks for it across 35 rate centres, split 37% mobile, 39% landline and 23% VoIP.
The other area codes laid over 339
Area code 339 does not have None to itself. 1 other code — 781 — 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.
7816,252 blocks, 40 rate centres, mostly landline
Each holds its own blocks and its own carrier mix, so a 339 number and a 781 number from the same street can report different line types. Filtering None by area code needs all 2 of them.
339 is not confined to None itself: its blocks sit across 35 rate centres, named in the table below.
Massachusetts is split across 9 area codes — 978, 781, 774, 508, 413, 339 and others. By allocated blocks 339 is the 8th largest of them, holding 3% of the Massachusetts total.
Where 339 numbers are concentrated
NANPA truncates rate-centre names to ten characters and drops the spaces, which is why Lynn and Bryantvl are shortened. Names are reproduced as recorded rather than expanded — the abbreviation is the key the block data is filed under.

The largest holder, Onvoy, has 25% of the code.
These are original allocations. A number keeps its digits and its block when its subscriber moves network, so a ported 339 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 339?
Area code 339 covers Massachusetts. It is not the only code there: 781 is an overlay on the same rate centres, so a Massachusetts number can start with any of them.
Is a 339 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 339 the split runs 37% mobile, 39% landline and 23% VoIP, so landline is the most likely single answer.
Which carriers hold 339 numbers?
The largest holders are Onvoy, Verizon Wireless, Bandwidth. That is the carrier the block was allocated to, which is not necessarily the network a given number sits on today.
How many 339 numbers are there?
The code holds 1,113 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 339 covers on the order of 1,113,000 possible numbers — most of which have never been issued to anyone.
