MONTEVISTA prefixes in area code 719

NANPA records 6 assigned NXX blocks to rate center MONTEVISTA in area code 719, 0.9% of the 665 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. 5 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - CO (2), NEW CINGULAR WIRELESS PCS, LLC (1), ONVOY, LLC - CO (1). The earliest assignment on record here is 2005-01-12 and the most recent 2022-12-13. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
