HYDEN prefixes in area code 606

NANPA records 5 assigned NXX blocks to rate center HYDEN in area code 606, 0.8% of the 639 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 (2), NEW CINGULAR WIRELESS PCS, LLC - GA (1), LESLIE COUNTY TEL. CO. (1). The earliest assignment on record here is 2002-06-26 and the most recent 2007-10-12. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
