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 3 prefixes, Cloverdale 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 Cloverdale 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.
