ROCHESTER prefixes in area code 585
NANPA records 296 assigned NXX blocks to rate center ROCHESTER in area code 585, 43.8% 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. 38 holders hold those blocks, the largest being FRONTIER TELEPHONE OF ROCHESTER, INC. (116), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - NY (54), NEW CINGULAR WIRELESS PCS, LLC - DC (28). The earliest assignment on record here is 2001-04-20 and the most recent 2026-10-09. 175 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 217, 248, 270, 360 – overlay codes cover the same geography, so a rate center is served by all of them.
