ROCHESTER prefixes in area code 603
NANPA records 16 assigned NXX blocks to rate center ROCHESTER in area code 603, 2.1% of the 752 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 CONSOLIDATED COMM OF NO. NEW ENGLAND-NH (4), COMCAST IP PHONE, LLC (2), PAETEC ITEL, LLC (2). The earliest assignment on record here is 2001-09-24 and the most recent 2023-07-05. 12 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.
