NORWICH prefixes in area code 607
NANPA records 12 assigned NXX blocks to rate center NORWICH in area code 607, 2.2% 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 CITIZENS TELECOMM CO OF NY DBA FRONTIER COMM OF NY (4), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - NY (3), OMNIPOINT COMMUNICATIONS, INC. - NY (2). The earliest assignment on record here is 2002-07-10 and the most recent 2026-01-08. 10 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
