NORTHAMPTN prefixes in area code 413

NANPA records 19 assigned NXX blocks to rate center NORTHAMPTN in area code 413, 3.1% of the 605 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. 9 holders hold those blocks, the largest being PAETEC ITEL, LLC (5), VERIZON NEW ENGLAND INC. (5), LEVEL 3 COMMUNICATIONS, LLC - MA (2). The earliest assignment on record here is 2001-01-22 and the most recent 2025-04-14. 13 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 484, 610, 835 – overlay codes cover the same geography, so a rate center is served by all of them.
