GROVETON prefixes in area code 936

NANPA records 3 assigned NXX blocks to rate center GROVETON in area code 936, 0.7% of the 422 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 CENTURYLINK COMMUNICATIONS, LLC (1), ONVOY, LLC - TX (1), VALOR TELECOMM TX, LP-TX #1 DBA WINDSTREAM COMM SW (1). The earliest assignment on record here is 2017-02-03 and the most recent 2021-07-26. 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 code 603 – overlay codes cover the same geography, so a rate center is served by all of them.
