Content CredentialsA signed record (C2PA) of how the file was made, sealed so any change shows.

Suno says it attaches C2PA-based Content Credentials to songs when they are downloaded, identifying each as AI-generated content made with Suno, so that downstream services can tell a track came from Suno even after re-sharing. The credentials apply only to new downloads, not to songs already downloaded; Suno gives no start date.

Suno does not name the signer. An example credential on its Safety Center lists the provider as Suno, Inc.

Quoted passage FAQ, What are content credentials?

Content Credentials are based on C2PA, an open industry standard used across the tech industry that shows where a piece of content came from and how it was made. When a song is downloaded from Suno, we attach metadata identifying it as AI-generated content made with Suno.

Yes. Suno’s content credentials use C2PA, the same open standard used by other content companies. This means you don’t have to specifically use our tool to check a song. Any app or service that supports content credentials can read the label in a Suno file, and the label travels with the file wherever it’s shared.
