STAR LAKE prefixes in area code 315

NANPA records 4 assigned NXX blocks to rate center STAR LAKE in area code 315, 0.5% of the 781 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. 4 holders hold those blocks, the largest being TC SYSTEMS, INC. - NY (1), NORTHLAND NETWORKS, LTD. - NY (1), ONVOY, LLC- NY (1). 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
