SAFFORD prefixes in area code 928
NANPA records 34 assigned NXX blocks to rate center SAFFORD in area code 928, 5.3% of the 637 blocks assigned in the code.

The earliest assignment on record here is 2001-12-18 and the most recent 2026-01-14. 28 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
