ZABCIKVL prefixes in area code 254

NANPA records 3 assigned NXX blocks to rate center ZABCIKVL 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. 2 holders hold those blocks, the largest being ONVOY, LLC - TX (2), BRIGHTSPEED OF TEXAS, INC. (1). The earliest assignment on record here is 2017-05-05 and the most recent 2021-07-27. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
