HAYSI prefixes in area code 276

NANPA records 4 assigned NXX blocks to rate center HAYSI in area code 276, 1.1% of the 374 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 EAST KENTUCKY NETWRK, LLC DBA APPALACHIAN WIRELESS (1), TWILIO INTERNATIONAL, INC. (1), TON80 COMMUNICATIONS, LLC (1). The earliest assignment on record here is 2021-12-23 and the most recent 2021-12-23. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
