The “ISRC already exists” error is a common issue faced by artists during music distribution. ISRC stands for International Standard Recording Code and is a unique identifier assigned to each sound recording.

This error usually occurs when the same ISRC code is used for more than one track incorrectly. Each unique recording must have its own ISRC.

One common reason is re-uploading the same track with a different distributor while using the same ISRC. This is allowed only if the audio is exactly the same and you are maintaining continuity.

Another reason is duplicate uploads. If you upload the same song multiple times with the same ISRC but different metadata, it may trigger a conflict.

Sometimes, distributors auto-generate ISRCs. If you manually enter an ISRC that already exists in their system, it can cause this error.

To fix this issue, first identify whether the track is a duplicate or a new version. If it is the same recording, reuse the same ISRC correctly and ensure metadata matches exactly.

If it is a different version (remix, remaster, edited version), you must generate a new ISRC.

If the error is caused by a previous release, you may need to take down the old release or contact your distributor for correction.

Best practices to avoid this error:
- Use one ISRC per unique recording
- Do not reuse ISRC for different versions
- Keep metadata consistent across platforms
- Maintain a proper ISRC database for your catalog

Proper ISRC management ensures smooth distribution and accurate royalty tracking.
