HOOKER prefixes in area code 580

NANPA records 3 assigned NXX blocks to rate center HOOKER in area code 580, 0.4% of the 741 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 PANHANDLE TELECOMMUNICATIONS SYSTEMS, INC. (1), PANHANDLE TELEPHONE COOPERATIVE, INC. (1), LEVEL 3 COMMUNICATIONS, LLC - OK (1). The earliest assignment on record here is 2003-05-29 and the most recent 2026-05-14. 1 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
