CHEYENNE prefixes in area code 307
NANPA records 60 assigned NXX blocks to rate center CHEYENNE in area code 307, 12.0% of the 499 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. 28 holders hold those blocks, the largest being QWEST CORPORATION (14), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - WY (8), ONVOY, LLC - WY (5). The earliest assignment on record here is 2002-06-11 and the most recent 2026-01-07. 42 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 580 – overlay codes cover the same geography, so a rate center is served by all of them.
