FRANKLIN prefixes in area code 607

NANPA records 3 assigned NXX blocks to rate center FRANKLIN in area code 607, 0.5% 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. 3 holders hold those blocks, the largest being TWC IP ENABLED SERVICES, LLC (1), ONVOY, LLC- NY (1), CITIZENS TELECOMM CO OF NY DBA FRONTIER COMM OF NY (1). The earliest assignment on record here is 2007-01-25 and the most recent 2023-07-05. 3 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 207, 217, 270, 304 – overlay codes cover the same geography, so a rate center is served by all of them.
