YUMA prefixes in area code 928
NANPA records 65 assigned NXX blocks to rate center YUMA in area code 928, 10.2% of the 637 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. 12 holders hold those blocks, the largest being QWEST CORPORATION (20), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - AZ (14), T-MOBILE USA, INC. (9). The earliest assignment on record here is 2001-12-18 and the most recent 2025-08-07. 46 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 520, 970 – overlay codes cover the same geography, so a rate center is served by all of them.
