TICONDROGA prefixes in area code 518

NANPA records 5 assigned NXX blocks to rate center TICONDROGA in area code 518, 0.6% 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. 5 holders hold those blocks, the largest being TC SYSTEMS, INC. - NY (1), CROWN POINT NTWK TECH INC DBA BRIDGE POINT COMM-NY (1), VERIZON NEW YORK, INC. (1). The earliest assignment on record here is 2012-12-17 and the most recent 2012-12-17. 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.
