MIDVALE prefixes in area code 385
NANPA records 40 assigned NXX blocks to rate center MIDVALE in area code 385, 8.1% 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. 13 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC (14), ONVOY, LLC - UT (8), COMCAST IP PHONE, LLC (4). The earliest assignment on record here is 2009-08-21 and the most recent 2026-09-15. 40 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 208, 801 – overlay codes cover the same geography, so a rate center is served by all of them.
