OSWEGO prefixes in area code 315

NANPA records 15 assigned NXX blocks to rate center OSWEGO in area code 315, 1.9% 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. (5), PAETEC ITEL, LLC (3), OMNIPOINT COMMUNICATIONS, INC. - NY (2). The earliest assignment on record here is 2001-08-14 and the most recent 2001-08-14. 12 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 331, 620, 630, 680 – overlay codes cover the same geography, so a rate center is served by all of them.
