Navigate to https://e-justice.europa.eu and select the BORIS (Beneficial Ownership Registers Interconnection System) search interface
Enter the company name and select the member state (country) of incorporation; BORIS queries the relevant national register via a decentralized lookup
Review returned beneficial owner records including full name, nationality, country of residence, month and year of birth, and nature and extent of ownership interest
For automated or bulk lookups, check whether the target member state's national register exposes a direct API (e.g., Ireland's RBO at rbo.gov.ie, Netherlands KVK at api.kvk.nl) and prefer direct national register APIs for programmatic access
Apply for 'obliged entity' access where required; under the 6th AMLD framework, access tiers differ between competent authorities, AML-obliged entities, and members of the public
Document your legitimate interest justification for each query in jurisdictions that require it; store the justification text alongside the query result for audit purposes
Known gotchas
There is no REST API for BORIS itself; it is a web portal aggregating national register responses — programmatic access requires direct integration with each member state's national register, which varies significantly in API availability and data format
37% of EU national UBO registers require national eID or restrict access to domestic obliged entities; cross-border access is fragmented and the 6th AMLD transposition deadline for operational rules is July 2026, after which access rules will evolve
Ownership threshold for reporting UBO status is generally 25% equity or voting rights in most EU jurisdictions, but some states apply lower thresholds; do not assume uniformity across member states
