EROCHESTER prefixes in area code 585
NANPA records 29 assigned NXX blocks to rate center EROCHESTER in area code 585, 4.3% 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. 10 holders hold those blocks, the largest being FRONTIER TELEPHONE OF ROCHESTER, INC. (11), NEW CINGULAR WIRELESS PCS, LLC - DC (5), OMNIPOINT COMMUNICATIONS, INC. - NY (4). The earliest assignment on record here is 2002-06-10 and the most recent 2024-07-05. 19 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 code 330 – overlay codes cover the same geography, so a rate center is served by all of them.
