Hormigueros, PR — rate center

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

Routing-wise it sits in LATA 820.

Multiple area codes over one rate center (787/939) is the overlay pattern: same geography, different first three digits.

With only 4 prefixes, Hormigueros sits at the small end of Puerto Rico'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 Hormigueros 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.
