Comparison of the top registered agent services for Arizona LLCs and corporations · Updated 2026-04-30
Picking the right Arizona registered agent means trading off price against privacy, in-state expertise, and customer support quality. Under A.R.S. §29-3115, the agent must keep a physical Arizona street address and be available during normal business hours; a P.O. box alone will not satisfy the Arizona Corporation Commission.
