DENVER prefixes in area code 983
NANPA records 33 assigned NXX blocks to rate center DENVER in area code 983, 68.8% of the 48 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. 16 holders hold those blocks, the largest being ONVOY, LLC - CO (7), WIDE VOICE, LLC - CO (6), NEW CINGULAR WIRELESS PCS, LLC (3). The earliest assignment on record here is 2023-06-02 and the most recent 2026-10-20. 32 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 223, 303, 319, 660 – overlay codes cover the same geography, so a rate center is served by all of them.
