GRANDCNYON prefixes in area code 928
NANPA records 7 assigned NXX blocks to rate center GRANDCNYON in area code 928, 1.1% of the 637 blocks assigned in the code.

The earliest assignment on record here is 2020-12-22 and the most recent 2022-02-01. 6 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
