MONAHANS prefixes in area code 432

NANPA records 6 assigned NXX blocks to rate center MONAHANS in area code 432, 1.8% 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. 5 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - IL (2), CSC VOICE, LLC (1), FRACTEL, LLC (1). The earliest assignment on record here is 2001-03-13 and the most recent 2024-03-04. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
