ALEXNDRIBY prefixes in area code 315

NANPA records 5 assigned NXX blocks to rate center ALEXNDRIBY in area code 315, 0.6% 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. 5 holders hold those blocks, the largest being TC SYSTEMS, INC. - NY (1), VERIZON NEW YORK, INC. (1), LEVEL 3 COMMUNICATIONS, LLC - NY (1). 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
