GLENWD SPG prefixes in area code 970

NANPA records 21 assigned NXX blocks to rate center GLENWD SPG in area code 970, 2.7% of the 786 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 T-MOBILE USA, INC. (7), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - CO (5), QWEST CORPORATION (4). The earliest assignment on record here is 2001-04-24 and the most recent 2025-04-14. 12 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
