BELLEFONTN prefixes in area code 251

NANPA records 8 assigned NXX blocks to rate center BELLEFONTN in area code 251, 1.5% of the 528 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 ONVOY, LLC - AL (2), NEW CINGULAR WIRELESS PCS, LLC - GA (2), PAETEC ITEL, LLC (1). The earliest assignment on record here is 2004-01-19 and the most recent 2023-11-03. 8 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
