KOSSE prefixes in area code 254

NANPA records 3 assigned NXX blocks to rate center KOSSE in area code 254, 0.4% 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. 3 holders hold those blocks, the largest being BRIGHTSPEED OF EASTERN TEXAS, INC. (1), AMA COMM., LLC DBA AMA*TECHTEL COMMUNICATIONS-TX (1), ONVOY, LLC - TX (1). The earliest assignment on record here is 2015-06-08 and the most recent 2019-07-22. 2 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
