HOPEVALLEY prefixes in area code 401

NANPA records 10 assigned NXX blocks to rate center HOPEVALLEY in area code 401, 1.7% of the 581 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. 9 holders hold those blocks, the largest being OMNIPOINT MIAMI E LICENSE, LLC (2), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (1), AT&T - LOCAL (1). The earliest assignment on record here is 2001-01-16 and the most recent 2004-03-03. 9 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
