An ISRC (International Standard Recording Code) is a unique identifier for each sound recording. Think of it like a fingerprint for your track—it follows that recording for life, no matter who owns it or where it’s released. For example, if you release the same recording as both a single and as part of an album, it keeps the same ISRC.

This article covers what ISRCs are, when you need new ones, and how to find the codes assigned to your music in your CD Baby account.

What is an ISRC?

• An ISRC is a permanent code assigned to a specific recording.
• It applies to the sound recording itself, not the underlying composition.
• Each version of a recording needs its own ISRC.

How long is an ISRC valid?

• Once assigned, an ISRC identifies that track for its entire life.
• It never changes, even if ownership of the recording changes.
• The same ISRC is used any time the original, unaltered track is reused (such as on a compilation or album re-release).

When do I need a new ISRC?

You’ll need a new code if the recording is changed in any meaningful way, such as:

• Remixes or edits.
• Any change to track length of more than 10 seconds.
• Using part of a previously released recording in a new compilation.
• "Full restoration” work like remastering, re-pitching, or noise reduction.
• Rebranding (changing metadata tied to the track). (Not recommended.)
• For a full list of cases, see the ISRC handbook.

How do I get ISRCs from CD Baby?

• CD Baby automatically assigns ISRCs during the inspection stage of your release—unless you already have your own codes.
• If you need them sooner (for example, before release to set up promo materials), you can request ISRCs early.
• To do this, make sure you’ve submitted your track list and paid for your release.

How do I find my assigned ISRCs?

• Log in to your CD Baby account
• Click “Album & Singles” 
• Click "view/edit" next to the release in question
• Scroll down and click the "Tracks & Audio" heading
• From here you will see a summary each track with the ISRC code(s) listed on the right
• To see a full list, click any ISRC to open the ISRC summary page.

What about ISWC codes?

• ISWC = International Standard Musical Work Code.
• ISWCs identify the composition (songwriting), not the recording.
• They are assigned by your performing rights organization (like ASCAP or BMI in the U.S.).
• CD Baby doesn’t assign ISWCs.
• You can usually find ISWCs in your PRO’s public repertoire database.

ISRCs for Brazilian Artists

• Since July 2022, Brazil’s national phonogram register allows ISRCs generated by aggregators like CD Baby.
• Don't worry—ISRCs we assign are valid and can be registered later with no issues.

Things to Note

• Always use your existing ISRCs if you already have them.
• ISRCs are tied to metadata, so avoid rebranding unless necessary.
• CD Baby’s ISRCs are valid worldwide.
• For deeper technical details, check out the official ISRC site.
