LATROBE prefixes in area code 724

NANPA records 9 assigned NXX blocks to rate center LATROBE in area code 724, 1.1% 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. 5 holders hold those blocks, the largest being VERIZON PENNSYLVANIA, INC. (5), LEVEL 3 COMMUNICATIONS, LLC - PA (1), FIDIUM ENTERPRISE SERVICES, LLC (1). 7 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
