NEW HAVEN prefixes in area code 260

NANPA records 8 assigned NXX blocks to rate center NEW HAVEN in area code 260, 1.8% of the 444 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. 5 holders hold those blocks, the largest being FRONTIER NORTH, INC.. - IN (3), ONVOY, LLC - IN (2), COMCAST IP PHONE, LLC (1). The earliest assignment on record here is 2007-05-02 and the most recent 2023-02-01. 6 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, 304, 475, 502 – overlay codes cover the same geography, so a rate center is served by all of them.
