It helps prevent confusion between recordings and facilitates rights management across various formats, distribution channels, and products. Once assigned, the ISRC remains a constant reference point, whether the recording is used by music services, internationally, or under different licensing agreements.
The ISRC is assigned by the first maker and must never be altered or modified. It is a mandatory requirement when declaring a sound recording or music video. However, the ISRC code itself cannot be used to identify a copyright holder.
CB-YZ9
Prefix code: Assigned to the first maker. Two letters followed by three alphanumeric characters for a total of 5 characters
25
2 digits indicating the year in which the code was assigned (in the example 25 for the year 2025)
00001
Designation code: Five numbers, chosen and assigned by the first maker. (Ex: 00001, for a first code assigned to a track in 2025)
Each sound recording must be assigned a unique ISRC code. The code always remains unchanged, even if the sound recording is transferred to another rights holder. If any modifications are made later to an already published sound recording, a new ISRC code must be created for the new version of the recording.
