IPI stands for Interested Parties Information and is a unique number identifier for writers and publishers. IPIs are 11 digits in length and are used throughout the industry by Performance Rights Organizations (PRO) and Mechanical Rights Organizations (MRO). If you do not already have one for your publisher entity, CMRRA will request one from SUISA (Swiss Cooperative Society for Music Authors and Publishers or Swiss Society for the Rights of Authors of Musical Work). This process takes approximately 4 weeks from the time of request to SUISA, which is carried out monthly. Once received, CMRRA will make the update to your account and proceed with processing your Electronic Song Registration Form.
