CLAREMONT prefixes in area code 828

NANPA records 7 assigned NXX blocks to rate center CLAREMONT in area code 828, 1.0% of the 724 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. 6 holders hold those blocks, the largest being BANDWIDTH.COM CLEC, LLC - NC (2), BELLSOUTH TELECOMM INC DBA SOUTHERN BELL TEL & TEL (1), WINDSTREAM COMMUNICATIONS, INC. - NC (1). The earliest assignment on record here is 2006-12-27 and the most recent 2022-07-05. 6 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 507, 603, 605, 618 – overlay codes cover the same geography, so a rate center is served by all of them.
