MOUNTAINCY prefixes in area code 423
NANPA records 6 assigned NXX blocks to rate center MOUNTAINCY in area code 423, 0.8% of the 764 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. 5 holders hold those blocks, the largest being SUNCOM DBA T-MOBILE USA (2), BANDWIDTH.COM CLEC, LLC - TN (1), NEW CINGULAR WIRELESS PCS, LLC - GA (1). The earliest assignment on record here is 2001-08-31 and the most recent 2023-04-06. 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 code 775 – overlay codes cover the same geography, so a rate center is served by all of them.
