GOLDFIELD prefixes in area code 515

NANPA records 3 assigned NXX blocks to rate center GOLDFIELD in area code 515, 0.5% of the 578 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 UNITED STATES CELLULAR - IA (1), EDGETEL, LLC (1), GOLDFIELD TEL. CO. (1). The earliest assignment on record here is 2017-09-05 and the most recent 2020-01-16. 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 775 – overlay codes cover the same geography, so a rate center is served by all of them.
