CLEARFIELD prefixes in area code 801

NANPA records 19 assigned NXX blocks to rate center CLEARFIELD in area code 801, 2.4% of the 783 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. 4 holders hold those blocks, the largest being QWEST CORPORATION (14), TELEPORT COMMUNICATIONS AMERICA, LLC - UT (2), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (2). 7 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 385, 582, 605, 641 – overlay codes cover the same geography, so a rate center is served by all of them.
