An ISNI (International Standard Name Identifier) is a 16-digit identifier that uniquely identifies a person or organisation involved in creative work. For musicians, ISNI solves a real problem: the same artist name appears across hundreds of databases with inconsistent spellings, different associated works, and no single authoritative reference. ISNI provides that reference.
What is an ISNI?
ISNI (International Standard Name Identifier) is a 16-digit unique identifier for public identities involved in creative works — authors, artists, performers, labels, publishers, and organisations. It is defined by ISO 27729 and managed by the ISNI International Authority (ISNI-IA). An ISNI looks like this: 0000 0001 2103 2683 (the ISNI for David Bowie). It is a persistent, globally unique identifier that remains valid regardless of name changes, misspellings, or the retirement of the system that assigned it. ISNI is the international standard answer to the problem of name disambiguation: two artists with the same name, or the same artist with a name that has been spelled differently across different databases, can be unambiguously distinguished using their ISNIs.
Why musicians need ISNI
The music industry runs on multiple overlapping databases: streaming platforms, collection societies (PRS, PPL, MCPS), rights management systems, libraries, and increasingly AI training datasets. Every database stores artist information independently, and every database has its own approach to name disambiguation. An artist named 'James Brown' or 'The Cure' could refer to dozens of different people or bands in different contexts. Without a persistent identifier, these databases cannot reliably link records for the same creator across systems. ISNI provides that link. A streaming platform, a PRO, and a library database can all reference the same ISNI and be certain they are referring to the same person. For rights attribution and royalty flow, this reliability matters: correct attribution means correct payment.
ISNI vs IPI vs IPN vs ISRC
These four identifiers are related but distinct:
- ISNI: identifies a person or organisation across all creative domains — music, books, film, and more. Issued by ISNI-IA via registration organisations including the British Library.
- IPI (Interested Party Information): identifies songwriters and publishers specifically within the performing rights ecosystem. Assigned by your PRO when you register as a member. IPI is music-industry specific; ISNI is cross-domain.
- IPN (International Performer Number): identifies performers specifically within the neighbouring rights ecosystem (PPL, SoundExchange, SCAPR member societies). Separate from IPI.
- ISRC (International Standard Recording Code): identifies a specific sound recording. Not a creator identifier — ISRC identifies works, not people.
- The relationship: an ISNI record can link to a person's IPI and IPN, creating a connected web of identifiers that allow databases to cross-reference records reliably.
How to get an ISNI in the UK
In the UK, ISNIs for musicians are issued by the British Library, which is one of the official ISNI registration agencies. The process:
- Apply via the British Library's ISNI registration service. The British Library reviews the application and, if the identity meets the ISNI criteria (the person has contributed to publicly available creative work), assigns an ISNI.
- Alternatively, ISNIs can be requested via ISNI-registered intermediaries including some music distributors, publishers, and collecting societies. PRS for Music, for example, encourages members to obtain ISNIs and may facilitate this.
- Provide documentation that uniquely identifies you and your publicly available creative work. For musicians, this typically means your artist name, commercial release history, and any existing IPI or IPN numbers.
- Once assigned, your ISNI appears in the ISNI public database at isni.org, where it can be referenced by any downstream system.
YouTube and ISNI
YouTube has implemented ISNI linking in its Content ID and YouTube Music systems. An artist whose profile on YouTube Music is linked to their ISNI can benefit from more accurate attribution across YouTube's music database and from better disambiguation in YouTube's recommendation systems. YouTube has been actively encouraging artists and their distributors to provide ISNIs as part of artist profile setup. For UK musicians distributing via major aggregators, confirming that your ISNI is included in your artist profile data is increasingly a best practice rather than an advanced option.
ISNI and AI training datasets
As AI systems are trained on creative content, accurate creator attribution in training data becomes commercially and legally significant. AI companies that want to attribute creative content to its creators — either for licensing, compensation, or compliance purposes — use ISNI as the standard identifier. A musician with an ISNI is more identifiable in AI training datasets than one without. In a world where AI-generated content attribution and AI training compensation are evolving rapidly, having a persistent, internationally recognised identity is increasingly valuable.
Code Group Music includes ISNI verification and application in its metadata administration service. Our catalog assessment identifies whether your artist profile has an ISNI and whether it is correctly linked to your IPI and IPN. Start at codegroupmusic.co.uk/#catalog-assessment.
Frequently Asked Questions
Is ISNI the same as an IPI number?
No. IPI (Interested Party Information) is a music-industry-specific identifier for songwriters and publishers within the PRO ecosystem. ISNI is a cross-industry standard that identifies creators across music, books, film, and all other creative domains. Your IPI is assigned when you join PRS. Your ISNI is a separate registration via the British Library or other ISNI registration agency.
Do I need an ISNI as an independent artist?
It is not mandatory, but it is increasingly beneficial. ISNIs enable better attribution across streaming platforms, library databases, and AI systems. For artists with catalog activity across multiple databases and jurisdictions, ISNI provides the disambiguation layer that ensures records are correctly linked.
Is my ISNI publicly visible?
Yes. The ISNI database at isni.org is publicly accessible. Your ISNI, your name, and your linked creative works are visible to anyone who searches the database. This is by design — ISNI's value comes from being a shared reference point across databases.
Can two artists with the same name have separate ISNIs?
Yes, this is precisely what ISNI is designed to handle. Two artists named 'James Brown' are assigned separate ISNIs, each linked to their distinct body of work. Systems that reference the ISNI rather than just the name can unambiguously distinguish between them.
