IPIs 

An Interested Parties Information (IPI) is a unique 11-digit number that identifies a rights holder as a member of a collective society for the management of musical or other intellectual property.  

When you join APRA or AMCOS your IPI number becomes yours for life - even if you join another collecting society or transfer your membership. 

The IPI system has been designed and developed by the International Confederation of Societies of Authors and Composers (CISAC), is managed by our international affiliate SUISA and is the backbone tool for the administration of collective intellectual property protection. 

You can find your IPI in the App, Writer Portal in your account or in the acknowledgement of membership email you receive from us once you've become a member. 

ISWCs 

The International Standard Musical Work Code (ISWC) is a unique, permanent and internationally recognised reference number for the identification of musical works. 

This identification number is linked to other valuable metadata for the work such as work title, creators, performers and any publishers. The ISWC distinguishes your musical work from other compositions around the world. 

All ISWCs are centrally assigned by the International Confederation of Societies of Authors and Composers (CISAC), and our team automatically allocates ISWCs as the final step in the of the work registration process.  It is possible to collect and pay royalties for performances of your works, even without an ISWC code. 

An ISWC consists of the letter “T” followed by 9 digits plus a “check digit” to protect the ISWC against allocation errors. An example ISWC is T-034.524.680-1.
