EUID Explained

What EUID is for

EUID (European Unique Identifier) is used in the context of interoperability between EU business registers (often referenced in BRIS-related contexts). It helps identify a company across registers and countries.

EUID vs national registry number

• EUID is an interoperability identifier.
• National registry numbers remain the primary legal registration identifier issued by each country’s register.

Where you might encounter EUID

• Cross-border register extracts or filings referencing another member state’s company record.
• Register interoperability portals or datasets.
• Compliance documentation that consolidates cross-border corporate information.

Verification approach

EUID is typically verified by resolving it back to the relevant business register entry and confirming the company details. Use the register’s official extract where required.
