Area code 208 is centred on Boise, Idaho. We hold 5,765 allocated blocks for it across 145 rate centres, split 43% mobile, 46% landline and 11% VoIP.
The other area codes laid over 208
Area code 208 does not have Boise to itself. 1 other code — 986 — 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.
9861,295 blocks, 110 rate centres, mostly VoIP
Each holds its own blocks and its own carrier mix, so a 208 number and a 986 number from the same street can report different line types. Filtering Boise by area code needs all 2 of them.
208 is not confined to Boise itself: its blocks sit across 145 rate centres, named in the table below.

Where 208 numbers are concentrated
NANPA truncates rate-centre names to ten characters and drops the spaces, which is why Mt Home and Tygee Vly 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 208 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 208?
Area code 208 covers Boise, Idaho. It is not the only code there: 986 is an overlay on the same rate centres, so a Boise, Idaho number can start with any of them.
Is a 208 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 208 the split runs 43% mobile, 46% landline and 11% VoIP, so landline is the most likely single answer.
Which carriers hold 208 numbers?
The largest holders are Verizon Wireless, Onvoy, Qwest Corporation. That is the carrier the block was allocated to, which is not necessarily the network a given number sits on today.
How many 208 numbers are there?
The code holds 5,765 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 208 covers on the order of 5,765,000 possible numbers — most of which have never been issued to anyone.
