FRASER prefixes in area code 970

NANPA records 9 assigned NXX blocks to rate center FRASER in area code 970, 1.1% 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. 6 holders hold those blocks, the largest being T-MOBILE USA, INC. (2), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - CO (2), QWEST CORPORATION (2). The earliest assignment on record here is 2002-02-06 and the most recent 2004-01-20. 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 code 748 – overlay codes cover the same geography, so a rate center is served by all of them.
