MUNCY prefixes in area code 570

NANPA records 5 assigned NXX blocks to rate center MUNCY in area code 570, 0.6% of the 782 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 WINDSTREAM PENNSYLVANIA, INC. (2), MCIMETRO ACCESS TRANSMISSION SERVICES LLC - PA (1), CORE COMMUNICATIONS, INC. - PA (1). The earliest assignment on record here is 2007-10-24 and the most recent 2009-03-19. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
