What does an ISRC identify?
An ISRC is associated with an individual sound recording. It helps connect observations of the same recording across releases and catalog data.
ISRC lookup for recording metadata and releases.
An ISRC identifies a specific sound recording. DistroCheck uses recording identifiers together with metadata and other signals rather than treating an ISRC by itself as distributor proof.
Look Up an ISRCISRC does not equal distributor
An ISRC is useful recording identity evidence, but it does not by itself establish who currently distributes the music. DistroCheck keeps recording identity and distributor evidence separate.
ISRC and UPC work at different levels
A release may contain multiple recordings, each with its own ISRC, while the release can have a UPC at the product level. Using both helps build a clearer map of recording and release relationships.
