MASSENA prefixes in area code 315

NANPA records 11 assigned NXX blocks to rate center MASSENA in area code 315, 1.4% 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. 8 holders hold those blocks, the largest being VERIZON NEW YORK, INC. (3), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - NY (2), NEW CINGULAR WIRELESS PCS, LLC - DC (1). The earliest assignment on record here is 2010-07-07 and the most recent 2016-02-29. 9 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 680, 712 – overlay codes cover the same geography, so a rate center is served by all of them.
