MINA prefixes in area code 775

NANPA records 6 assigned NXX blocks to rate center MINA in area code 775, 1.0% of the 601 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 ONVOY, LLC - NV (3), UTILITY TELECOM GROUP, LLC - NV (1), NEW CINGULAR WIRELESS PCS, LLC (1). The earliest assignment on record here is 2001-07-10 and the most recent 2021-08-18. 2 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
