HILO prefixes in area code 808
NANPA records 101 assigned NXX blocks to rate center HILO in area code 808, 14.6% of the 694 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. 17 holders hold those blocks, the largest being HAWAIIAN TELCOM, INC. - HI (45), T-MOBILE USA, INC. (11), NEW CINGULAR WIRELESS PCS, LLC (10). The earliest assignment on record here is 2001-04-24 and the most recent 2026-05-04. 44 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
