CORRIGAN prefixes in area code 936

NANPA records 8 assigned NXX blocks to rate center CORRIGAN in area code 936, 1.9% of the 422 blocks assigned in the code. A rate center is the billing geography a block is allocated to – NANPA truncates the name to ten characters, so read it as a NANPA label rather than a town. 6 holders hold those blocks, the largest being COMMIO, LLC (2), SOUTHWESTERN BELL (2), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - TX (1). The earliest assignment on record here is 2001-05-17 and the most recent 2026-09-01. 7 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
