CARY-RTP prefixes in area code 984

NANPA records 3 assigned NXX blocks to rate center CARY-RTP in area code 984, 1.0% 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. 3 holders hold those blocks, the largest being TELNYX LLC (1), METROPCS, INC. (1), ONVOY SPECTRUM, LLC (1). The earliest assignment on record here is 2015-03-06 and the most recent 2021-10-15. 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 919 – overlay codes cover the same geography, so a rate center is served by all of them.
