POST prefixes in area code 806

NANPA records 5 assigned NXX blocks to rate center POST in area code 806, 0.7% of the 734 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 CEBRIDGE TELECOM TX , L.P. - TX (2), VALOR TELECOMM TX, LP-TX #1 DBA WINDSTREAM COMM SW (2), POKA LAMBRO TELEPHONE COMPANY (1). The earliest assignment on record here is 2005-05-24 and the most recent 2015-07-01. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
