What is an ISRC?
An ISRC (International Standard Recording Code) is the 12-character ID attached to a single recording. Every version of a song, from the album cut to a remix or a radio edit, gets its own ISRC, and streaming services and collection societies use it to track plays and pay out royalties.
What is a UPC?
A UPC (Universal Product Code) identifies a release: a single, EP or album. It's the barcode number for the product as a whole, while each track inside it carries its own ISRC.
How do I find my ISRC?
Paste the Spotify link to your song above. Your distributor also lists it in your release dashboard, usually under the track details, and it appears on your royalty statements.
ISRC vs UPC:
One release, one UPC. One recording, one ISRC. A ten-track album has one UPC and ten ISRCs. If you re-release the same recording on a new album, the ISRC stays the same and the UPC changes.
