CORSICA prefixes in area code 814

NANPA records 3 assigned NXX blocks to rate center CORSICA in area code 814, 0.4% 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. 3 holders hold those blocks, the largest being WINDSTREAM PENNSYLVANIA, INC. (1), COMCAST IP PHONE, LLC (1), CORE COMMUNICATIONS, INC. - PA (1). The earliest assignment on record here is 2008-09-09 and the most recent 2009-03-17. 2 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 582, 605 – overlay codes cover the same geography, so a rate center is served by all of them.
