The International Standard Recording Code (ISRC) was introduced by the International Federation of the Phonographic Industry (IFPI) to facilitate the identification and tracking of the use of sound recordings globally.
Although it was initially developed for use in traditional products such as CDs the codes are becoming increasingly important in the digital environment as they are used to identify digital recordings. Given the vast number of digital recordings used everyday worldwide, the ability to effectively track use is becoming increasingly important if rights holders are to benefit from that use. Therefore, many digital distributors have made the use of the ISRC obligatory.
