GYPSUM prefixes in area code 970
NANPA records 5 assigned NXX blocks to rate center GYPSUM in area code 970, 0.6% 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. 5 holders hold those blocks, the largest being ONVOY, LLC - CO (1), CENTURYTEL OF EAGLE, INC. DBA CENTURYLINK (1), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (1). The earliest assignment on record here is 2003-04-08 and the most recent 2023-02-13. 3 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 785 – overlay codes cover the same geography, so a rate center is served by all of them.
