WALNUT SPG prefixes in area code 254

NANPA records 3 assigned NXX blocks to rate center WALNUT SPG 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 TON80 COMMUNICATIONS, LLC (1), VALOR TELECOMM TX, LD-TX #2 DBA WINDSTREAM COMM SW (1), LEVEL 3 COMMUNICATIONS, LLC - TX (1). 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
