BUENAVISTA prefixes in area code 719

NANPA records 7 assigned NXX blocks to rate center BUENAVISTA in area code 719, 1.1% 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 BANDWIDTH.COM CLEC, LLC - CO (3), QWEST CORPORATION (1), NEW CINGULAR WIRELESS PCS, LLC (1). The earliest assignment on record here is 2002-02-06 and the most recent 2023-06-27. 6 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 229, 540 – overlay codes cover the same geography, so a rate center is served by all of them.
