MARLIN prefixes in area code 254

NANPA records 11 assigned NXX blocks to rate center MARLIN in area code 254, 1.6% 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. 5 holders hold those blocks, the largest being T-MOBILE USA, INC. (4), SOUTHWESTERN BELL (3), LEVEL 3 COMMUNICATIONS, LLC - TX (2). The earliest assignment on record here is 2002-05-06 and the most recent 2024-11-11. 11 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
