CROTON FLS prefixes in area code 914

NANPA records 5 assigned NXX blocks to rate center CROTON FLS in area code 914, 0.7% of the 704 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 VERIZON NEW YORK, INC. (2), ONVOY, LLC- NY (1), TC SYSTEMS, INC. - NY (1). The earliest assignment on record here is 2012-10-26 and the most recent 2012-10-26. 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 codes 329, 845 – overlay codes cover the same geography, so a rate center is served by all of them.
