GRAND JCT prefixes in area code 970
NANPA records 57 assigned NXX blocks to rate center GRAND JCT in area code 970, 7.3% 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. 15 holders hold those blocks, the largest being QWEST CORPORATION (16), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - CO (10), T-MOBILE USA, INC. (8). The earliest assignment on record here is 2001-02-21 and the most recent 2025-10-30. 33 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 269, 515, 731 – overlay codes cover the same geography, so a rate center is served by all of them.
