CAZENOVIA prefixes in area code 315

NANPA records 3 assigned NXX blocks to rate center CAZENOVIA in area code 315, 0.4% 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. 2 holders hold those blocks, the largest being WINDSTREAM NEW YORK, INC. - FULTON (2), TWC IP ENABLED SERVICES, LLC (1). The earliest assignment on record here is 2011-05-09 and the most recent 2011-05-09. 2 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 608 – overlay codes cover the same geography, so a rate center is served by all of them.
