NORWOOD prefixes in area code 970

NANPA records 3 assigned NXX blocks to rate center NORWOOD in area code 970, 0.4% of the 786 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 CENTURYTEL OF EAGLE, INC. DBA CENTURYLINK (1), ONVOY, LLC - CO (1), TON80 COMMUNICATIONS, LLC (1). The earliest assignment on record here is 2007-07-09 and the most recent 2022-03-04. 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 315, 339, 417, 704 – overlay codes cover the same geography, so a rate center is served by all of them.
