Area code 669
Area code 669 covers San Jose, California. We hold 2,545 allocated blocks for it across 11 rate centres, split 47% mobile, 31% landline and 22% VoIP.
The other area codes laid over 669
Area code 669 does not have San Jose, California to itself. 1 other code — 408 — 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.
4085,103 blocks, 14 rate centres, mostly landline
Each holds its own blocks and its own carrier mix, so a 669 number and a 408 number from the same street can report different line types. Filtering San Jose, California by area code needs all 2 of them.

Common questions
Where is area code 669?
Area code 669 covers San Jose, California. It is not the only code there: 408 is an overlay on the same rate centres, so a San Jose, California number can start with any of them.
Is a 669 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 669 the split runs 47% mobile, 31% landline and 22% VoIP, so mobile is the most likely single answer.
Which carriers hold 669 numbers?
The largest holders are Onvoy, AT&T Wireless, 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 669 numbers are there?
The code holds 2,545 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 669 covers on the order of 2,545,000 possible numbers — most of which have never been issued to anyone.
