Comparison
ISRC vs UPC: What's the Difference?
ISRC vs UPC explained — recording codes vs product barcodes, when you need each, and how they work together in your metadata.
ISRC and UPC are the two codes in your release metadata, and artists often mix them up. The short version: ISRC identifies a single track, UPC identifies the whole release product.
ISRC
- Unique to each recording
- 12-character international code
- Follows the recording across releases
- Crucial for royalty matching
- Embedded in digital metadata
UPC
- Unique to each release/product
- Retail barcode standard
- One per album, single or EP
- Required by retailers
- Printed on physical packaging
The Verdict
You need both: one ISRC per track and one UPC per product. Correct codes are the foundation of accurate royalties and a clean catalog.
ISRC identifies the recording
Each track gets a unique 12-character ISRC. Platforms use it to match plays, streams and royalties to the exact recording.
Keep the same ISRC for the same recording across re-releases; new versions get new codes.
UPC identifies the product
Each release (single, EP or album) gets a UPC barcode that identifies it as a sellable product across retail and streaming.
An album has one UPC and as many ISRCs as it has tracks. Different formats (digital vs vinyl) are different products with different UPCs.
How they work together
Both codes travel in your metadata and are required for professional distribution. Accurate pairing keeps your release data clean across 200+ platforms.
Zaventra Music Group assigns and registers both codes for every release.
Frequently Asked Questions
Can a single have the same UPC as the album?
No — the single and the album are separate products with separate UPCs.
Do I need ISRC for every remix?
Yes — each distinct recording, including remixes and alternative versions, needs its own ISRC.
Who issues these codes?
ISRCs come from national agencies or distributors; UPCs come from GS1 or distributors. Zaventra assigns both.
