Why can’t I change my UPC after my release is approved?

A UPC identifies the release and can’t be changed after approval. This includes a UPC assigned by CD Baby or one you supplied.

Why the UPC is locked

Stores use the UPC to identify and track a release. Changing it after approval can disrupt matching and reporting.

If the UPC is incorrect

You’ll need to cancel the release and submit it again with the correct UPC. See more here: How do I cancel a release?
