Search options

A Check Certificate Authenticity service is available on the website.

Both the Issuance Number and the Business Registration Number are required to look up an organization's registration certificate.

Either Internet Explorer or a user agent switcher which enables your browser to be identified as Internet Explorer are required to access the service.

Find and use identifiers

The service cannot be used to look up the identifier for an organization, only to validate the authenticity of an identifier.
