Crisfield, MD — rate center

Routing-wise it sits in LATA 242.
Multiple area codes over one rate center (410/443/667) is the overlay pattern: same geography, different first three digits.
With only 3 prefixes, Crisfield sits at the small end of Maryland'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 Crisfield 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.
