An ISRC is an International Standard Recording Code, this is a code assigned to every track released. For example, each track on a 5-track EP will have 5 ISRC codes, and one UPC code.
Every single, EP or album released on Spinnup is assigned an ISRC, but if you would like to switch distributors to Spinnup and retain your existing ISRCs you can, click here for more information.
