WILLIAMSPT prefixes in area code 570

NANPA records 33 assigned NXX blocks to rate center WILLIAMSPT in area code 570, 4.2% 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. 11 holders hold those blocks, the largest being VERIZON PENNSYLVANIA, INC. (9), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - PA (7), NEW CINGULAR WIRELESS PCS, LLC - DC (7). The earliest assignment on record here is 2001-04-18 and the most recent 2016-03-22. 21 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, 240, 272, 301 – overlay codes cover the same geography, so a rate center is served by all of them.
