ALAMOSA prefixes in area code 719

NANPA records 13 assigned NXX blocks to rate center ALAMOSA in area code 719, 2.0% 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. 7 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - CO (3), LEVEL 3 COMMUNICATIONS, LLC - CO (3), NEW CINGULAR WIRELESS PCS, LLC (2). The earliest assignment on record here is 2002-05-02 and the most recent 2022-08-12. 8 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
