GUYMON prefixes in area code 580

NANPA records 7 assigned NXX blocks to rate center GUYMON in area code 580, 0.9% 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. 4 holders hold those blocks, the largest being PANHANDLE TELECOMMUNICATIONS SYSTEMS, INC. (3), PANHANDLE TELEPHONE COOPERATIVE, INC. (2), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - OK (1). The earliest assignment on record here is 2004-12-10 and the most recent 2004-12-10. 2 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots. The same rate center name also appears in area code 806 – overlay codes cover the same geography, so a rate center is served by all of them.
