Area code 707

Area code 707 is centred on Santa Rosa, California. We hold 6,813 allocated blocks for it across 75 rate centres, split 33% mobile, 48% landline and 20% VoIP.

The other area codes laid over 707

Area code 707 does not have Santa Rosa to itself. 1 other code — 369 — 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.

369

405 blocks, 32 rate centres, mostly mobile

Each holds its own blocks and its own carrier mix, so a 707 number and a 369 number from the same street can report different line types. Filtering Santa Rosa by area code needs all 2 of them.

707 is not confined to Santa Rosa itself: its blocks sit across 75 rate centres, named in the table below.

California is split across 40 area codes — 657, 707, 559, 209, 530, 213 and others. By allocated blocks 707 is the second largest of them, holding 4% of the California total.

Where 707 numbers are concentrated

NANPA truncates rate-centre names to ten characters and drops the spaces, which is why Ptlm Main and Ptlm Swift 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 16% of the code.

These are original allocations. A number keeps its digits and its block when its subscriber moves network, so a ported 707 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 707?

Area code 707 covers Santa Rosa, California. It is not the only code there: 369 is an overlay on the same rate centres, so a Santa Rosa, California number can start with any of them.

Is a 707 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 707 the split runs 33% mobile, 48% landline and 20% VoIP, so landline is the most likely single answer.

Which carriers hold 707 numbers?

The largest holders are Onvoy, Pacific Bell, AT&T Wireless. That is the carrier the block was allocated to, which is not necessarily the network a given number sits on today.

How many 707 numbers are there?

The code holds 6,813 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 707 covers on the order of 6,813,000 possible numbers — most of which have never been issued to anyone.
