MASONTOWN prefixes in area code 724

NANPA records 3 assigned NXX blocks to rate center MASONTOWN in area code 724, 0.4% 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. 3 holders hold those blocks, the largest being TELEPORT COMMUNICATIONS AMERICA, LLC - PA (1), VERIZON PENNSYLVANIA, INC. (1), CORE COMMUNICATIONS, INC. - PA (1). The earliest assignment on record here is 2001-03-12 and the most recent 2001-03-12. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
