What are ISRC and barcode in pre-saves?

What are release source codes?

When creating a pre-save, you may be asked to provide:

ISRC

This identifies your individual track.

Barcode (UPC)

This identifies your overall release.

These codes help connect your pre-save to your release on streaming platforms.

If you’re unsure:

• ISRC = track ID
• UPC = release ID
