CITRONELLE prefixes in area code 251

NANPA records 6 assigned NXX blocks to rate center CITRONELLE in area code 251, 1.1% 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. 5 holders hold those blocks, the largest being PAETEC ITEL, LLC (2), LEVEL 3 COMMUNICATIONS, LLC - AL (1), ONVOY SPECTRUM, LLC (1). The earliest assignment on record here is 2008-05-05 and the most recent 2023-06-29. 6 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
