LOCK HAVEN prefixes in area code 570

NANPA records 12 assigned NXX blocks to rate center LOCK HAVEN in area code 570, 1.5% 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. 8 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - PA (3), VERIZON PENNSYLVANIA, INC. (3), METROPCS, INC. (1). The earliest assignment on record here is 2001-04-18 and the most recent 2016-01-15. 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 code 272 – overlay codes cover the same geography, so a rate center is served by all of them.
