How GSEIN works
A permanent reference built from official sources.
GSEIN gives legal and economic entities a permanent, verifiable identifier designed for verification, interoperability and institutional use.
How GSEIN works
Official sources
National registries, LEI and trusted sources.
Entity resolution
Records are matched and resolved.
One GSEIN
One persistent GSEIN identifies the entity across systems.
A common entity identity across your systems
Banks, public authorities, registries and compliance teams keep their own identifiers. GSEIN gives each entity one reference that sits next to all of them.
- National registration ID
- LEI
- Internal customer ID
- Other trusted identifiers
