TONKAWA prefixes in area code 580
NANPA records 5 assigned NXX blocks to rate center TONKAWA in area code 580, 0.7% 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 BANDWIDTH.COM CLEC, LLC - OK (2), SOUTHWESTERN BELL (1), T-MOBILE USA, INC. (1). The earliest assignment on record here is 2002-04-16 and the most recent 2021-08-26. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
