CAMBDG CY prefixes in area code 765

NANPA records 5 assigned NXX blocks to rate center CAMBDG CY in area code 765, 0.7% of the 725 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 FRONTIER NORTH, INC.. - IN (2), NEW CINGULAR WIRELESS PCS, LLC - IL (1), LEVEL 3 COMMUNICATIONS, LLC - IN (1). The earliest assignment on record here is 2001-05-04 and the most recent 2002-08-19. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
