JAFFREY prefixes in area code 603

NANPA records 3 assigned NXX blocks to rate center JAFFREY in area code 603, 0.4% 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. 3 holders hold those blocks, the largest being CONSOLIDATED COMM OF NO. NEW ENGLAND-NH (1), PAETEC ITEL, LLC (1), COMCAST IP PHONE, LLC (1). The earliest assignment on record here is 2003-06-26 and the most recent 2022-09-29. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
