OWEGO prefixes in area code 607

NANPA records 8 assigned NXX blocks to rate center OWEGO in area code 607, 1.5% of the 548 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. 6 holders hold those blocks, the largest being TC SYSTEMS, INC. - NY (2), VERIZON NEW YORK, INC. (2), BANDWIDTH.COM CLEC, LLC - NY (1). The earliest assignment on record here is 2020-07-08 and the most recent 2024-02-23. 6 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
