Business Identity Validator

Business Identity Validator helps you confirm that a Swiss company exists, access its official registry data, and check who is authorised to sign on its behalf.

The data comes from the official Swiss registers: the Swiss UID register, which records companies and institutions under their Swiss enterprise identification number (UID); ZEFIX, the federal index of commercial-register entries; and the cantonal commercial registers that hold signatory and signing-rule data. The service queries those registers for you and returns normalised JSON, so you integrate once instead of against each register separately.
