FAIRMONT prefixes in area code 910

NANPA records 4 assigned NXX blocks to rate center FAIRMONT in area code 910, 0.5% of the 785 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 ONVOY, LLC - NC (1), MCIMETRO ACCESS TRANSMISSION SERVICES LLC - NC (1), BELLSOUTH TELECOMM INC DBA SOUTHERN BELL TEL & TEL (1). The earliest assignment on record here is 2004-08-24 and the most recent 2021-06-01. 4 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 304, 402, 472, 507 – overlay codes cover the same geography, so a rate center is served by all of them.
