MCCAMEY prefixes in area code 432

NANPA records 3 assigned NXX blocks to rate center MCCAMEY in area code 432, 0.9% of the 341 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. 3 holders hold those blocks, the largest being ONVOY, LLC - TX (1), FRACTEL, LLC (1), SOUTHWESTERN BELL (1). The earliest assignment on record here is 2017-03-14 and the most recent 2021-05-06. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
