Typically, through your distributor and once your songs are distributed.
An ISRC (International Sound Recording Code) is a 12-character alphanumeric code used to identify a unique sound recording. One song can have multiple ISRCs if more than one recording of the song has been released - like live, acoustic, or cover versions. Publishers, collection societies, and music services use ISRCs to match specific recordings to the underlying compositions.
ISRCs are typically assigned by labels or distributors. An ISRC looks like this: USS1Z9900001.
Each recording can only have one ISRC attached to it. This code should never be reused. For example, if an artist plans on releasing a 15-song album for public consumption, it would contain 15 unique ISRCs (one for each track).
Songtrust makes it easy to associate ISRC information with your song when you register, using our tool that pulls recording data from Spotify’s API.
If your songs have not been released on Spotify, but have been distributed, you should contact your distributor directly to get the correct ISRCs for your tracks.
You don’t need ISRCs until you have scheduled a commercial release for your music. If you don’t have commercially released music, you don’t need ISRCs (and very likely won’t need a publishing administrator).
