The International Standard Recording Code (ISRC) is an international standard code for uniquely identifying sound recordings and music video recordings. The code was developed by the recording industry in conjunction with the
ISO technical committee 46, subcommittee 9 (TC 46/SC 9), which codified the standard as ISO 3901 in 1986, and updated it in 2001.
An ISRC identifies a particular ''recording'', not the work (composition and lyrical content) itself. Therefore, different recordings, edits, and remixes of the same work should each have their own ISRC. Works are identified by
ISWC. Recordings

History
ISO 3901 was completed in 1986. In 1988, the
IFPI
The International Federation of the Phonographic Industry (IFPI) is the organisation that represents the interests of the recording industry worldwide. It is a non-profit members' organisation registered in Switzerland and founded in Italy in 1 ...
recommended that its member companies adopt ISRCs for music videos. In 1989, the ISO designated the IFPI as the
registration authority for ISRCs. The IFPI, in turn, delegated part of the administration of ISRCs to several dozen national agencies, which allocate ISRCs to both
record companies and individuals. The national agencies began assigning ISRCs for music videos in August 1989.
The Japanese recording industry began encoding ISRCs on
audio CDs in November 1989. The IFPI and the
Recording Industry Association of America

(RIAA) then developed detailed recommendations for this practice, and for ISRC assignment in general. The IFPI adopted the recommendations in March 1991 and they went into effect for IFPI members on 1 January 1992.
Format

ISRC codes are always 12 characters long, in the form "CC-XXX-YY-NNNNN". The hyphens are not part of the ISRC code itself, but codes are often presented that way in print to make them easier to read. The four parts are as follows:
* "CC" is the appropriate two-character country code for the ISRC issuer. The code is assigned according to the
ISO 3166-1-Alpha-2 standard. (High demand for ISRCs within the United States has caused the supply of available registrant codes to become exhausted; after December 6, 2010, new registrants in the US use country code "QM". The codes "CP" and "DG" are reserved for further overflow, and "ZZ" is reserved for codes assigned by the International ISRC Agency. Further additions continue to be made.)
* "XXX" is a three character alphanumeric registrant code of the ISRC issuer. This number by itself does NOT uniquely identify the ISRC issuer as the same 3-digit registrant code may be used in various countries for different issuers. To uniquely identify an issuer, the country code and registrant code should be used together.
* "YY" represent the last two digits of the reference year – the year that the ISRC was assigned to the recording. This is not necessarily the date the recording was made.
* "NNNNN" is a 5-digit number that identifies the particular sound or video recording, unique within the scope of the reference year.

Embedding ISRC in files
ISRC may be embedded in most file formats as
metadata. Example formats include MP3, M4A, AAC, FLAC, and WAV for audio and MP4 or M4V for video.

* Audio CDs defined by the
Red Book may also embed ISRC as part of the
CD-Text information.
Metadata formats are not generally interchangeable as format converters may fail to translate the data. As a result, it is recommended to perform the embedding separately for each format.
Obtaining ISRCs
The provision of ISRCs is overseen by appointe
national ISRC agencies These national ISRC agencies issue codes directly to the public and may also utilize authorized ISRC Managers to issue ISRCs. In the United States, the appointed agency is
