SARANAC LK prefixes in area code 518

NANPA records 8 assigned NXX blocks to rate center SARANAC LK in area code 518, 1.0% of the 775 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. 7 holders hold those blocks, the largest being VERIZON NEW YORK, INC. (2), TC SYSTEMS, INC. - NY (1), TVC ALBANY, INC. DBA FIRSTLIGHT FIBER (1). The earliest assignment on record here is 2002-01-21 and the most recent 2016-04-04. 5 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 code 838 – overlay codes cover the same geography, so a rate center is served by all of them.
