CARLISLE prefixes in area code 717

NANPA records 24 assigned NXX blocks to rate center CARLISLE in area code 717, 3.1% 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. 8 holders hold those blocks, the largest being BRIGHTSPEED OF PENNSYLVANIA, LLC (9), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - PA (4), D&E/OMNIPOINT WIREL JOINT VENT LP DBA PCS ONE (3). The earliest assignment on record here is 2001-06-27 and the most recent 2016-07-22. 17 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, 859, 870 – overlay codes cover the same geography, so a rate center is served by all of them.
