MEXIA prefixes in area code 254

NANPA records 10 assigned NXX blocks to rate center MEXIA in area code 254, 1.5% of the 672 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 SOUTHWESTERN BELL (3), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - TX (2), NEW CINGULAR WIRELESS PCS, LLC - IL (2). The earliest assignment on record here is 2001-05-29 and the most recent 2026-02-04. 8 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
