Group Company Membership

Best Value!


Individuals who are employed by the same company that would like to benefit from IIAR’s offerings can join collectively as a Group Company Membership. Group members may be employed at the same facility or at an additional facility that is not an autonomous division or wholly owned subsidiary. The group must select a group administrator who assigns all members of the group.  The administrator must select one individual who is identified as the Voting Member, who will be the company representative for the group in all matters of IIAR coming before membership and requiring a vote. All other members within a group membership are considered non-voting.  A company may have an unlimited number of group members based on pricing structure outlined below. Please contact IIAR if you have any questions about your eligibility membership@iiar.org.

Group Company Membership Pricing

  • $2,000 – 2 to 5 individuals
  • $4,000 – 6 to 10 individuals
  • $6,000 – 11 to 15 individuals
  • $8,000 – 16 to 20 individuals

Note: If a group membership is purchased, and all persons defined, then a few months later, the company wished to add a new member they would have to ask IIAR to update invoicing manually.  A special request must be submitted.


Individual Company Membership


Individual Company membership is a single membership where you, as the member, are registered under your company of employment. You are automatically designated as the voting member who will be the company representative in all matters of IIAR coming before membership and requiring a vote. If additional employees from the company would like to join, it would require you to upgrade to Group Company Membership. 

The price for an Individual Company Membership is $1,000

If think your company might already have a group company membership and you wish to be added to that Group, please contact us at  membership@iiar.org, and we can confirm and put you in touch with the group company administrator.
