International Standard Recording Code
An ISRC, as defined in ISO 3901, identifies musical recordings independent from the distribution media, i.e. independent from a specific CD and independent from a digital music store.
" identification system for sound recordings and music videorecordings. Each ISRC is a unique and permanent identifier for a specific recording " 
CCXXXYYNNNNN CC-XXX-YY-NNNNN example: AR-F04-02-00386
- CC: country code
- no new registrant prefixes starting with US- are available, QM now used as CC for new US registrant .
- XXX: three character alphanumeric registrant code, uniquely identifying the organisation which registered the code.
- YY: last two digits of the year of registration
- NNNNN: specific number
Definition of recording
- 4.9.2 Changes in the playing time: " When a change of duration is intended ‘musically or artistically’, a new ISRC should be allocated. The recommended threshold is 10 seconds"
- 188.8.131.52 30-second clips: As even 30-second clips need to be licensed, they can be ‘separately exploited’ (see Section 4.1.2 Separate Exploitation). Therefore they should be allocated a distinct ISRC
- 4.9.6 Restoration of historical recordings: Re-mastering and editing technologies (including re-pitching, re-equalising, de-noising, de-clicking, etc.) offer many ways of processing historical recordings in order that they meet contemporary quality standards. When a full restoration of sound quality is carried out, the processed recording is to be considered a separate recording and thus obtain a new ISRC
Music recordings with the same ISRC can appear on different CDs. So if you suggest to a DJ he should play a specific recording you could do this via ISRC. He himself can then figure out from which CD to obtain it.
Recent CDs contain the ISRC's directly and they can be read with software.
