WARRENTON prefixes in area code 252

NANPA records 7 assigned NXX blocks to rate center WARRENTON in area code 252, 1.0% of the 695 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 LEVEL 3 COMMUNICATIONS, LLC - NC (2), MCIMETRO ACCESS TRANSMISSION SERVICES LLC - NC (2), BRIGHTSPEED OF EASTERN NORTH CAROLINA, LLC (1). The earliest assignment on record here is 2004-11-29 and the most recent 2007-09-06. 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 codes 503, 540, 636, 706 – overlay codes cover the same geography, so a rate center is served by all of them.
