TROY prefixes in area code 518
NANPA records 34 assigned NXX blocks to rate center TROY in area code 518, 4.4% 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. 11 holders hold those blocks, the largest being VERIZON NEW YORK, INC. (16), PAETEC ITEL, LLC (6), TC SYSTEMS, INC. - NY (3). The earliest assignment on record here is 2002-06-04 and the most recent 2024-03-14. 26 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 codes 208, 248, 254, 272 – overlay codes cover the same geography, so a rate center is served by all of them.
