Beaver, OR — rate center
The Beaver rate center (Oregon) anchors 4 active prefixes under area codes 503, 971. Rate centers, not city limits, are what phone numbers are legally tied to.
NANPA records show 4 active prefixes here across 3 carriers. 3 prefixes participate in thousands-block pooling, so blocks of 1,000 numbers are shared between carriers.
Routing-wise it sits in LATA 672.
Multiple area codes over one rate center (503/971) is the overlay pattern: same geography, different first three digits.
With only 4 prefixes, Beaver sits at the small end of Oregon's rate centers — a handful of carrier blocks cover the whole locality, and a number from here is a fairly strong locality signal (before porting is considered).
As always with US numbering: a prefix anchored to Beaver tells you where the block was issued. The person calling may have ported the number, moved away, or be spoofing it entirely — verify callers through independently found contact details.
