MECHANCSBG prefixes in area code 717

NANPA records 18 assigned NXX blocks to rate center MECHANCSBG in area code 717, 2.3% 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. 10 holders hold those blocks, the largest being VERIZON PENNSYLVANIA, INC. (8), PAETEC ITEL, LLC (2), LEVEL 3 COMMUNICATIONS, LLC - PA (1). The earliest assignment on record here is 2009-10-15 and the most recent 2016-11-16. 14 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 223, 326, 765, 937 – overlay codes cover the same geography, so a rate center is served by all of them.
