CLEARFIELD prefixes in area code 385

NANPA records 26 assigned NXX blocks to rate center CLEARFIELD in area code 385, 5.3% of the 495 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. 9 holders hold those blocks, the largest being TELEPORT COMMUNICATIONS AMERICA, LLC - UT (12), BANDWIDTH.COM CLEC, LLC - UT (4), ONVOY, LLC - UT (3). The earliest assignment on record here is 2012-03-30 and the most recent 2025-04-14. 26 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 582, 605, 641, 801 – overlay codes cover the same geography, so a rate center is served by all of them.
