WELLSBORO prefixes in area code 570

NANPA records 5 assigned NXX blocks to rate center WELLSBORO in area code 570, 0.6% of the 782 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 COMMONWEALTH TELEPHONE COMPANY LLC (2), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - PA (1), NEW CINGULAR WIRELESS PCS, LLC - DC (1). The earliest assignment on record here is 2004-08-25 and the most recent 2009-03-20. 3 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 code 272 – overlay codes cover the same geography, so a rate center is served by all of them.
