2 central-office prefixes are currently anchored to this rate center across 2 carriers. 2 prefixes participate in thousands-block pooling, so blocks of 1,000 numbers are shared between carriers.
The rate center belongs to the Portland-Vancouver-Hillsboro, OR-WA Metropolitan Statistical Area. 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 2 prefixes, Carlton 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).
Treat this data as geography of the number, not of the caller: porting, VoIP and caller-ID spoofing all detach the two. When a call matters, hang up and call back through an official number.
