TELLURIDE prefixes in area code 970

NANPA records 7 assigned NXX blocks to rate center TELLURIDE in area code 970, 0.9% 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 QWEST CORPORATION (2), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - CO (2), LEVEL 3 COMMUNICATIONS, LLC - CO (1). The earliest assignment on record here is 2001-02-13 and the most recent 2005-03-01. 6 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
