The other area codes laid over 971
Area code 971 does not have Portland to itself. 1 other code — 503 — 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.
5034,419 blocks, 63 rate centres, mostly landline
Each holds its own blocks and its own carrier mix, so a 971 number and a 503 number from the same street can report different line types. Filtering Portland by area code needs all 2 of them.
971 is not confined to Portland itself: its blocks sit across 55 rate centres, named in the table below.
Oregon is split across 4 area codes — 541, 971, 503, 458. By allocated blocks 971 is the second largest of them, holding 27% of the Oregon total.
Where 971 numbers are concentrated
NANPA truncates rate-centre names to ten characters and drops the spaces, which is why Mcminnvl and Stfrd-Sndy 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 971 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 971?
Area code 971 covers Portland, Oregon. It is not the only code there: 503 is an overlay on the same rate centres, so a Portland, Oregon number can start with any of them.
Is a 971 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 971 the split runs 52% mobile, 29% landline and 19% VoIP, so mobile is the most likely single answer.
Which carriers hold 971 numbers?
The largest holders are AT&T Wireless, Onvoy, Verizon Wireless. That is the carrier the block was allocated to, which is not necessarily the network a given number sits on today.
How many 971 numbers are there?
The code holds 4,519 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 971 covers on the order of 4,519,000 possible numbers — most of which have never been issued to anyone.
