Area code 369
Area code 369 is centred on Santa Rosa, California. We hold 405 allocated blocks for it across 32 rate centres, split 63% mobile, 5% landline and 32% VoIP.
The other area codes laid over 369
Area code 369 does not have Santa Rosa to itself. 1 other code — 707 — 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.
7076,813 blocks, 75 rate centres, mostly landline
Each holds its own blocks and its own carrier mix, so a 369 number and a 707 number from the same street can report different line types. Filtering Santa Rosa by area code needs all 2 of them.
369 is not confined to Santa Rosa itself: its blocks sit across 32 rate centres, named in the table below.
California is split across 40 area codes — 657, 707, 559, 209, 530, 369 and others. By allocated blocks 369 is the 38th largest of them, holding 0% of the California total.
Where 369 numbers are concentrated
NANPA truncates rate-centre names to ten characters and drops the spaces, which is why Bridgevl and Ptlm Swift are shortened. Names are reproduced as recorded rather than expanded — the abbreviation is the key the block data is filed under.

These are original allocations. A number keeps its digits and its block when its subscriber moves network, so a ported 369 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 369?
Area code 369 covers Santa Rosa, California. It is not the only code there: 707 is an overlay on the same rate centres, so a Santa Rosa, California number can start with any of them.
Is a 369 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 369 the split runs 63% mobile, 5% landline and 32% VoIP, so mobile is the most likely single answer.
Which carriers hold 369 numbers?
The largest holders are AT&T Wireless, Onvoy, T-Mobile Usa, Inc.. That is the carrier the block was allocated to, which is not necessarily the network a given number sits on today.
How many 369 numbers are there?
The code holds 405 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 369 covers on the order of 405,000 possible numbers — most of which have never been issued to anyone.
