HENRIETTA prefixes in area code 585
NANPA records 12 assigned NXX blocks to rate center HENRIETTA in area code 585, 1.8% of the 676 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 FRONTIER TELEPHONE OF ROCHESTER, INC. (4), MCIMETRO ACCESS TRANSMISSION SERVICES LLC - NY (1), TWC IP ENABLED SERVICES, LLC (1). The earliest assignment on record here is 2007-09-29 and the most recent 2024-12-30. 10 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 816, 940 – overlay codes cover the same geography, so a rate center is served by all of them.
