KRUM prefixes in area code 940

NANPA records 3 assigned NXX blocks to rate center KRUM in area code 940, 0.6% of the 506 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 CSC VOICE, LLC (1), BRIGHTSPEED OF TEXAS, INC. (1), FRACTEL, LLC (1). The earliest assignment on record here is 2021-05-07 and the most recent 2021-05-07. 2 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
