ALFRED prefixes in area code 607

NANPA records 3 assigned NXX blocks to rate center ALFRED 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. 2 holders hold those blocks, the largest being CITIZENS TELECOMM CO OF NY DBA FRONTIER COMM OF NY (2), TWC IP ENABLED SERVICES, LLC (1). The earliest assignment on record here is 2007-03-01 and the most recent 2007-03-01. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
