## What Is an IPI?

An IPI (Interested Parties Information) number uniquely identifies a music rights holder — a songwriter, composer, lyricist, or music publisher. Every professional songwriter registered with a PRO has an IPI number.

- Format: 9–11 digit numeric code  e.g. 00521765837
- Managed by: SUISA on behalf of CISAC
- Legacy name: Formerly called CAE (Composer, Author, Publisher) numbers
- Key distinction: IPI identifies a person or company holding music rights, not a specific song. An IPI maps to a catalog of works and recordings. Compare with ISNI, which covers creative contributors across all industries (not just music rights holders).
