MARKLESBG prefixes in area code 814

NANPA records 5 assigned NXX blocks to rate center MARKLESBG in area code 814, 0.6% of the 784 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 COMCAST IP PHONE, LLC (2), BRIGHTSPEED OF PENNSYLVANIA, LLC (1), CORE COMMUNICATIONS, INC. - PA (1). The earliest assignment on record here is 2007-04-18 and the most recent 2009-03-16. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
