FABENS prefixes in area code 915

NANPA records 6 assigned NXX blocks to rate center FABENS in area code 915, 1.6% of the 367 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 VALOR TELECOMM TX, LD-TX #2 DBA WINDSTREAM COMM SW (3), ONVOY, LLC - TX (2), FRACTEL, LLC (1). The earliest assignment on record here is 2015-07-01 and the most recent 2025-02-06. 6 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
