Parties that want to connect to AMS-IX Chicago have an option of becoming a member of the AMS-IX Association. Members receive the same services and have the same benefits as customers. The technical requirements and terms and conditions are the same. The additional advantage, and requirement, that membership brings is the ability to attend and vote in the AMS-IX Association General Meeting. Member representatives may also be nominated for the AMS-IX Executive Board.

In the AMS-IX General Meeting a number of items are presented to and discussed with the members, such as the Annual Accounts, the Long Term Commercial Strategy, business and technical updates and operational reviews as well as the elections of the Board. In case a network is willing to actively participate in discussions and exert influence regarding these topics then a membership of the Association is advisable. In case the network sees AMS-IX Chicago as primarily a service provider then being a customer is more straightforward.
