CHOCTAW prefixes in area code 405

NANPA records 3 assigned NXX blocks to rate center CHOCTAW in area code 405, 0.4% of the 783 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 COMCAST IP PHONE, LLC (1), OKLAHOMA COMMUNICATION SYSTEM, INC. (1), ONVOY, LLC - OK (1). The earliest assignment on record here is 2021-06-17 and the most recent 2021-06-17. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
