This document can be used to change the name of the corporation, its articles of incorporation, its registered agent, its principal office, or its directors and officers. There are two types of Arizona Articles of Amendment — Nonprofit: Short Form and Long Form. The Short Form is used when the changes being made are limited to the name of the corporation, its registered agent, and/or its principal office. The Long Form is used for all other changes, such as amendments to the articles of incorporation or changes to the directors and officers. Both forms must be signed by the corporation's president and secretary and filed with the Arizona Corporation Commission.
