ISWC (International Standard Musical Work Code) is the international identifier assigned to a musical composition — lyrics and melody. While ISRC identifies the sound recording, ISWC identifies the work itself (the publishing side).
ISRC vs ISWC
| Code | Identifies | Used By |
|---|---|---|
| ISRC | Sound recording (master) | Artist, label, distributor |
| ISWC | Composition (lyrics+melody) | Songwriter, publisher |
| UPC/EAN | Release (album/single) | Label, distributor |
How to Get an ISWC
ISWC is automatically assigned when you register your work through your PRO (e.g. MESAM in Turkey, ASCAP/BMI/SESAC in the US). Entering correct work information in your SOOLY Music distribution panel helps ensure accurate royalty tracking.
