Code uniquely identifying an audio recording
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 remastered or revised in other ways are usually assigned a new ISRC.

ISO 3901 was completed in 1986. In 1988, the IFPI 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.

ISRC may be embedded in most file formats as metadata. Example formats include MP3, M4A, AAC, FLAC, OGG, and WAV for audio and MP4, M4V, or MKV for video. The standard for the ID3v2.2 tag that was designed for use in MP3 files, was published in March 2019 and defined a way to embed ISRCs in a 'TSRC' frame. In August 2020, Barry Grint and the European Broadcasting Union published a specification for embedding ISRCs in Broadcast Wave Format, a WAV with metadata format. 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.

The provision of ISRCs is overseen by appointed 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 RIAA. ISRC codes can be obtained in large blocks directly from RIAA for an administrative fee ($95 at time of this publication), in quantities as little as 1 from ISRC. com ($2 $5), or in conjunction with other music related services from other authorized ISRC managers. In territories where there is no national ISRC agency, users can obtain ISRC codes directly from IFPI or from ISRC. com, Quansic and Sound Credit.
