SOMERSET prefixes in area code 814

NANPA records 14 assigned NXX blocks to rate center SOMERSET in area code 814, 1.8% 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. 9 holders hold those blocks, the largest being VERIZON NORTH, INC. - PA (4), NEW CINGULAR WIRELESS PCS, LLC - IL (2), ONVOY, LLC - PA (2). The earliest assignment on record here is 2001-03-14 and the most recent 2019-07-30. 9 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 220, 534, 582, 606 – overlay codes cover the same geography, so a rate center is served by all of them.
