GREELEY prefixes in area code 970

NANPA records 62 assigned NXX blocks to rate center GREELEY in area code 970, 7.9% 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. 14 holders hold those blocks, the largest being QWEST CORPORATION (18), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - CO (11), T-MOBILE USA, INC. (11). The earliest assignment on record here is 2001-04-24 and the most recent 2026-06-01. 39 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 308, 563, 748, 785 – overlay codes cover the same geography, so a rate center is served by all of them.
