COALGATE prefixes in area code 580
NANPA records 4 assigned NXX blocks to rate center COALGATE 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. 4 holders hold those blocks, the largest being UNITED STATES CELLULAR - OK (1), IP HORIZON LLC (1), ONVOY, LLC - OK (1). The earliest assignment on record here is 2026-03-06 and the most recent 2026-03-06. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
