Frequently asked questions about the Spain KYB API
What company data can I verify in Spain?
For a Spain company, the API returns the company record read live from the COLEGIO DE REGISTRADORES DE LA PROPIEDAD Y MERCANTILES DE ESPAÑA (CORPME): the entity name, type, status, registration number, address, and registration date, along with the controlling parties, and the available registry documents. See the table above for the full Spain availability.
Does the API return beneficial ownership (UBO) data for Spain companies?
For Spain, the COLEGIO DE REGISTRADORES DE LA PROPIEDAD Y MERCANTILES DE ESPAÑA (CORPME) does not publish shareholder or beneficial-owner data, so the API returns the company record and the controlling parties and officers rather than a shareholder or beneficial-owner list. Where you need ownership for an entity in a jurisdiction that does publish it, the recursive org-chart (GET /v2/Companies/{caseCommonId}/org-chart) resolves it. See the UBO API.
Can I retrieve official registry documents for Spain companies?
Yes. The default document set for Spain includes Registry Extract, retrieved by default. List and download them with the documents endpoint (GET /v2/Companies/{caseCommonId}/documents).
Is there a free sandbox for testing Spain company verification?
Yes. The Know Your Customer sandbox at https://api.knowyourcustomer.dev is a free, high-fidelity test environment. Request free sandbox access to start testing.
