Identity Domains

Identity domains are structured systems or namespaces that govern how unique identifiers are assigned, managed, validated, and recognized across organizations, industries, or governments.

What Identity Domains Define?

Identity Domains define:

• ✅ Scope – what type of entity is being identified (e.g. person, product, country, organization, etc.)

• 🏛️ Authority / Policy – who issues and maintains the ID (e.g. government, standards body, global registry)

• 🔄 Interoperability – how those IDs are used and trusted across systems

🤔Think of them like “realms” where IDs are meaningful

Examples

a passport number is valid within the government-issued identity domain, while a GTIN is valid within the global product trade domain.
