MANGUM prefixes in area code 580

NANPA records 4 assigned NXX blocks to rate center MANGUM in area code 580, 0.5% 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 CELLCO PARTNERSHIP DBA VERIZON WIRELESS - OK (2), TELEPORT COMMUNICATIONS AMERICA OK - LLC (1), SOUTHWESTERN BELL (1). The earliest assignment on record here is 2002-10-18 and the most recent 2022-02-07. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
