NO JACKSON prefixes in area code 234

NANPA records 3 assigned NXX blocks to rate center NO JACKSON in area code 234, 0.8% of the 398 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 TELNYX LLC (1), CSC VOICE, LLC (1), ONVOY, LLC - OH (1). The earliest assignment on record here is 2021-03-24 and the most recent 2024-03-12. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots. The same rate center name also appears in area code 330 – overlay codes cover the same geography, so a rate center is served by all of them.
