NEWTON prefixes in area code 617

NANPA records 48 assigned NXX blocks to rate center NEWTON in area code 617, 6.2% of the 768 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. 12 holders hold those blocks, the largest being VERIZON NEW ENGLAND INC. (20), PAETEC ITEL, LLC (5), NEW CINGULAR WIRELESS PCS, LLC - DC (5). The earliest assignment on record here is 2001-05-02 and the most recent 2005-02-28. 27 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 229, 304, 316, 334 – overlay codes cover the same geography, so a rate center is served by all of them.
