NEW HAVEN prefixes in area code 641

NANPA records 17 assigned NXX blocks to rate center NEW HAVEN in area code 641, 2.9% of the 584 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. 1 holder holds those blocks, the largest being FARMERS TEL. CO. (17). The earliest assignment on record here is 2005-12-01 and the most recent 2006-10-16. The same rate center name also appears in area codes 203, 260, 304, 475 – overlay codes cover the same geography, so a rate center is served by all of them.

The holder is who received the block from the numbering administrator. It is not necessarily the carrier serving a given number: numbers move with their owners, and a pooled block is shared.

Same rate center in other codes

Overlay codes cover the same geography, so one rate center is served by all of them.
