Pocomoke, MD — rate center

NANPA rate center & CO code data, current as of July 28, 2026.

Phone numbers "from Pocomoke" are, precisely speaking, numbers whose prefixes are anchored to the Pocomoke rate center of Maryland, under 410, 443, 667.

4 central-office prefixes are currently anchored to this rate center across 4 carriers. 3 prefixes participate in thousands-block pooling, so blocks of 1,000 numbers are shared between carriers.

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 4 prefixes, Pocomoke 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).

Treat this data as geography of the number, not of the caller: porting, VoIP and caller-ID spoofing all detach the two. When a call matters, hang up and call back through an official number.
