THREE OAKS prefixes in area code 269

NANPA records 5 assigned NXX blocks to rate center THREE OAKS in area code 269, 0.9% of the 545 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. 5 holders hold those blocks, the largest being ONVOY, LLCV - MI (1), AT&T - LOCAL (1), INTERACTIVE SERVICES NETWORK, INC. (1). The earliest assignment on record here is 2002-01-16 and the most recent 2022-09-16. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
