MIPI Alliance uses a tiered membership structure, similar to other industry organizations, to enable participation from large and small companies representing the mobile and mobile-influenced industries. The members include adopters, contributors, promoters and the board of directors.

Companies that are only interested in licensing and using the specifications can join at the adopter level. Companies that join at the contributor level can attend meetings, participate in working groups and help define specifications. Promoters, which are elected by the board from the set of contributors, have the rights of contributors as well as a voting board seat. Board members have the rights of promoters and permanent board seats.
