NEWTON prefixes in area code 409

NANPA records 3 assigned NXX blocks to rate center NEWTON in area code 409, 0.7% of the 434 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 VALOR TELECOMM TX, LD-TX #2 DBA WINDSTREAM COMM SW (2), ONVOY, LLC - TX (1). The earliest assignment on record here is 2015-06-10 and the most recent 2021-07-06. 2 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.
