The chapter, section by section

  1. Section 1

    Read the Arizona requirement

    Every LLC must name a registered agent with an in-state street address.

    Reference: azleg.gov (edition of October 2026)

  2. Section 2

    Determine who may serve

    An Arizona resident, or a corporation or LLC formed in Arizona or authorized to do business there. The appointment takes effect only once the agent accepts it in writing. Authority: A.R.S. § 29-3115.

  3. Section 3

    The address rule

    The address has to be a place of business or residence in Arizona with a street address. A P.O. box can be listed only as a separate Arizona mailing address.

    The public record shows the service's address.

  4. Section 4

    Serve as your own agent or hire one

    If you qualify, you may name yourself. A professional from the list costs $99 to $149 annually.

  5. Section 5

    Name the agent in the filing

    The agent is named when the Articles of Organization (Form L010) is filed, and a later change is a separate filing with the Arizona Corporation Commission.

    Reference: azcc.gov (edition of October 2026)

  6. Section 6

    Update the record when facts change

    Nothing is filed yearly here, so the statutory agent is what needs attention.
