CLAYTON prefixes in area code 984

NANPA records 5 assigned NXX blocks to rate center CLAYTON in area code 984, 1.7% of the 296 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 NEW CINGULAR WIRELESS PCS, LLC - GA (2), SUNCOM DBA T-MOBILE USA (1), ONVOY, LLC - NC (1). The earliest assignment on record here is 2017-05-12 and the most recent 2024-02-23. 5 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 codes 208, 217, 315, 317 – overlay codes cover the same geography, so a rate center is served by all of them.
