COLMESNEIL prefixes in area code 409

NANPA records 3 assigned NXX blocks to rate center COLMESNEIL in area code 409, 0.7% of the 434 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. 2 holders hold those blocks, the largest being VALOR TELECOMM TX, LD-TX #2 DBA WINDSTREAM COMM SW (2), TON80 COMMUNICATIONS, LLC (1). The earliest assignment on record here is 2015-07-01 and the most recent 2022-02-16. 2 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
