The ISRC (International Standard Recording Code) is the international identification system for sound recordings and music video recordings. Each ISRC is a unique and permanent identifier for a specific recording, independent of the format on which it appears (CD, audio file, etc) or the rights holders involved. Only one ISRC should be issued to a track, and an ISRC can never represent more than one unique recording.
ISRCs are used in digital commerce by download sites and collecting societies. An ISRC can also be permanently encoded into a product as its digital fingerprint. Encoded ISRC provide the means to automatically identify recordings for royalty payments.

ISRC codes are to the digital world what the UPC code is to the retail world.
