ISRC vs UPC — What's the Difference?
Two essential codes in the music industry that serve very different purposes. Here's everything you need to know about how ISRC and UPC codes compare.
Quick Summary
ISRC

UPC

| Length | 12 characters | 12 digits (UPC-A) or 13 digits (EAN) |
| Who assigns it | National ISRC agencies, labels, or distributors | GS1 (via member organizations) or distributors |

| Standard | ISO 3901 | GS1 / ISO 15420 |
Do I Need Both?
Yes, typically you need both. Here's why:
- An album with 10 tracks would have 1 UPC (for the album) and 10 ISRCs (one per track).
- A single release would have 1 UPC and 1 ISRC.
- Most digital distributors (DistroKid, CD Baby, TuneCore, etc.) assign both automatically when you upload a release.
- Streaming platforms require both codes for proper cataloging and royalty tracking.
When to Use Which
Use ISRC when...
- Tracking a specific recording across platforms
- Filing Content ID claims on YouTube
- Registering recordings with collecting societies
- Identifying a track for royalty collection
- Switching distributors (keep the same ISRC to preserve streams)
Use UPC when...
- Listing a release for sale (physical or digital)
- Setting up pre-orders on streaming platforms
- Tracking sales of a specific release
- Barcoding physical products (CDs, vinyl)
- Submitting releases to chart reporting organizations
Key Differences Explained
The simplest way to understand the difference: ISRC = track, UPC = release.
An ISRC is permanently tied to a specific recording. If you remix or remaster a track, the new version gets a new ISRC. But if you put the same recording on multiple albums, it keeps the same ISRC throughout.
A UPC is tied to a product package. Each album, EP, or single release gets its own UPC. If you release the same tracks as both a standard and deluxe edition, each edition gets its own UPC — even though the shared tracks keep the same ISRCs.
