Garibaldi, OR — rate center
Phone numbers "from Garibaldi" are, precisely speaking, numbers whose prefixes are anchored to the Garibaldi rate center of Oregon, under 503, 971.
The rate center currently carries 3 working prefixes across 3 carriers. 2 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 3 prefixes, Garibaldi 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).
A Garibaldi prefix on caller ID is a starting point, not proof of origin — numbers travel with their owners and displays can be spoofed. Use official callback numbers for anything sensitive.
