Frequently Asked Questions
Contact the ISRC Agency for your territory. An up to date, alphabetical list of ISRC Agencies is available on the ISRC Agency Contact page. If there is no ISRC Agency in your territory, you can obtain an ISRC from the International ISRC Registration Authority.
The ISRC is made up of three elements: Prefix Code, Year of Reference and Designation Code. For more details see the syntax description in the ISRC Handbook [at Section 3.3.1].
The five characters you have been allocated are your unique Prefix Code. To generate individual ISRCs per recording, you will need to add a two digit Year of Reference element to the Prefix, followed by a unique five digit Designation Code.
- The Year of Reference is the last two digits of the year in which the ISRC is assigned.
- The Designation Code is a set of five digits generated by you, usually in sequence beginning from number 00001 and unique to you within each Year of Reference. See full syntax description in the ISRC Handbook at Section 3.3.1
No. Once an ISRC has been assigned to a track the ISRC should remain the same for the lifespan of the track. This is the case even if the ownership of the track changes.
For more information see ISRC Handbook Section 4.6.
These are some of the modifications to a recording that would require the assignment of a new ISRC:
• Restoration of historical recordings, where creative changes are involved
• Changes in playing time which exceed 10 seconds
• Remixes/edits
More detailed information can be found in the ISRC Handbook at Annex A.6 onwards.
Yes. A sound recording and a music video recording are different recordings, even if the audio component in the video is the same as the sound recording. Because they are different recordings, the music video and sound recording must be assigned different unique ISRCs.
More detailed information can be found in the ISRC Handbook at Section 3.1.
No. ISRC is not for identifying audio-visual works. It is for identifying sound recordings and music video recordings. The only exception to this would be short excerpts such as interviews contained within a music concert recording, which may be assigned ISRC for consistency with other elements in the overall recorded content. In general, audio-visual works are identified by ISAN [ISAN (International Standard Audiovisual Number)] and EIDR | EIDR – A universal unique identifier for movie and television assets).
No. Once assigned, an ISRC must not be re-used under any circumstances. More detailed information is available in the ISRC Handbook at Section 4.1.3
It is possible to embed ISRC into a video file format which supports ID3 tags, such as MP4. Tag editing tools exist which can be used to insert ISRC into the ID3 tag field of a recording or batch of recordings (eg: Kid3 - Audio Tagger (kde.org))
The method of providing ISRCs to YouTube together with video content depends on how you access YouTube.
The MP4 video format allows ISRC to be embedded in the video file. This facilitates dissemination of ISRC together with the video, including when uploaded to YouTube. This method may be appropriate for individuals uploading to YouTube via YouTube Studio, where there is currently no method of supplying ISRC in the metadata panes provided with YouTube Studio.
If you are a YouTube Music Partner you will have been provided with tools to provide ISRC and other data to YouTube.. More information is available from YouTube on their website
If you are uploading directly to YouTube with a DDEX feed, ISRC should be provided as part of the DDEX data.
If you are uploading to YouTube through a third party service provider (i.e. a music aggregator or distribution service) please check with your service provider as to the status of providing ISRCs of your recordings to YouTube. Most providers can deliver ISRCs assigned by right holders, and/or they can assign ISRC on behalf of right holders and supply them in their feeds to YouTube.
Compact Disc
In the case of Compact Discs the ISRCs and other PQ-data are encoded in the disc subcode (Q channel) in the disc mastering process. For this reason, ISRCs must be encoded for each track in the Pre-Master for CD. The ISRCs together with the Digital Copy Prohibited flag (if appropriate), and the relevant point of sale code (e.g. EAN/UPC) should be inserted on the Pre-Master during the pre-mastering process from the original Master.
Electronically Distributed Music
Most formats for electronically distributed music allow the inclusion of an ISRC, which can be inserted by authoring software. Where electronically distributed formats include several tracks, the ISRC of each track should be associated with it in the metadata of the file.
MP3s
The MP3 format does allow rights management information like ISRC to be included however it is rarely used. What is used is the ID3 system of tags, which is not part of the international standard, but does enable ISRC to be encoded. It is therefore recommended that an ISRC be encoded into the ID3 tag.
For more information see ISRC Handbook Section 4.9.
Yes, ISRCs can be applied to promotional material such as 30-second clips and hidden tracks particularly if at any time in the future the asset may be separately exploited – this does not necessarily imply monetary value. More detailed information is available in the ISRC Handbook at Sections 4.1.2 and 4.6
Classical music often comprises parts such as movements or arias which are separately exploited. It is generally appropriate to identify with distinct ISRCs each part which can be separately exploited, A further distinct ISRC should be used to identify the overall recording. More detailed information is available in the ISRC Handbook at Annex A.14.
Yes. Ring sounds are short audio recordings, and can be assigned an ISRC. More detailed information is available in the ISRC Handbook at Annex A.9.11
The international ISRC database is one of a number of searchable locations for ISRC. It is provided to the music industry by Soundexchange. The international ISRC database references repertoire data submitted to Soundexchange and is updated on a daily basis. If the recording you are searching for does not appear, it may be because the Soundexchange database has not completed its daily update, or the repertoire has not been submitted to Soundexchange.
ISRC is the International Sound Recording Code. ISRC is used to identify sound recordings and music videos. ISWC is the International Standard Musical Work Code. ISWC is used to identify musical works (compositions).
ISWC is maintained for ISO by the ISWC International Agency and identifies musical compositions produced by composers and authors. The ISWC International Agency is operated by the International Confederation of Societies of Authors and Composers CISAC
CISAC offers online access to ISWC data via the ISWCnet search.
No. ISRC is only assigned to identify recording. It does not identify the product into which the product is embedded or carried, regardless of whether this is a CD or digital file. Music products require their own identifiers, which allow management of aspects such as price, tracking within supply chains and distinguishing between different formats or encodings. ISRC identifies the recording regardless of supply chain, price or format.
Music products are generally identified by UPC/EAN barcodes for physical and digital releases. UPC/EAN codes may be required by collective rights management organisations as part of the repertoire registration process. Each different product requires its own UPC/EAN code.
