Detroit, AL — rate center
The Detroit rate center (Alabama) anchors 2 active prefixes under area codes 205, 659. Rate centers, not city limits, are what phone numbers are legally tied to.
The rate center currently carries 2 working prefixes across 2 carriers. 2 prefixes participate in thousands-block pooling, so blocks of 1,000 numbers are shared between carriers.
Routing-wise it sits in LATA 476.
Multiple area codes over one rate center (205/659) is the overlay pattern: same geography, different first three digits.
With only 2 prefixes, Detroit sits at the small end of Alabama'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 Detroit 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.
