LEHI prefixes in area code 385

NANPA records 13 assigned NXX blocks to rate center LEHI in area code 385, 2.6% 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 QWEST CORPORATION (2), FIRSTDIGITAL COMMUNICATIONS, LLC (2), ELECTRIC LIGHTWAVE LLC DBA ALLSTREAM (2). The earliest assignment on record here is 2012-05-29 and the most recent 2024-03-18. 13 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 801 – overlay codes cover the same geography, so a rate center is served by all of them.
