NEWMILFORD prefixes in area code 272

NANPA records 18 assigned NXX blocks to rate center NEWMILFORD in area code 272, 5.3% of the 337 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. 2 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - DC (17), TON80 COMMUNICATIONS, LLC (1). The earliest assignment on record here is 2022-01-10 and the most recent 2026-04-29. 18 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 570, 779, 815, 860 – overlay codes cover the same geography, so a rate center is served by all of them.
