NEW CASTLE prefixes in area code 724

NANPA records 24 assigned NXX blocks to rate center NEW CASTLE in area code 724, 3.1% of the 783 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. 10 holders hold those blocks, the largest being VERIZON PENNSYLVANIA, INC. (7), AERIAL COMMUNICATIONS, INC. (3), LEVEL 3 COMMUNICATIONS, LLC - PA (3). The earliest assignment on record here is 2001-03-12 and the most recent 2017-03-09. 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 302, 540, 765, 878 – overlay codes cover the same geography, so a rate center is served by all of them.
