SALADO prefixes in area code 254

NANPA records 6 assigned NXX blocks to rate center SALADO in area code 254, 0.9% 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. 4 holders hold those blocks, the largest being ONVOY, LLC - TX (2), LEVEL 3 COMMUNICATIONS, LLC - TX (2), MCIMETRO ACCESS TRANSMISSION SERVICES LLC - TX (1). The earliest assignment on record here is 2006-07-27 and the most recent 2022-12-21. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
