NEW HAVEN prefixes in area code 475
NANPA records 43 assigned NXX blocks to rate center NEW HAVEN in area code 475, 14.7% of the 292 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. 14 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - CT (11), ONVOY, LLC - CT (8), OMNIPOINT COMMUNICATIONS, INC. - CT (6). The earliest assignment on record here is 2010-02-17 and the most recent 2026-08-06. 43 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 203, 260, 304, 502 – overlay codes cover the same geography, so a rate center is served by all of them.
