Astoria, OR — rate center
The Astoria rate center (Oregon) anchors 12 active prefixes under area codes 503, 971. Rate centers, not city limits, are what phone numbers are legally tied to.
The rate center currently carries 12 working prefixes across 8 carriers. 11 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.
A Astoria 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.
