List of ISO 9000 Registered Companies

Finding a list of ISO 9001 registered companies has been problematic in the past. As of today, IAF’s Database Management Committee (DMC); represented by the Accreditation Bodies – including ANAB, Certification Bodies, and Industry, is developing a global database to provide a source for validating accredited certifications issued worldwide. You can find a link to the database below, and search for ISO 9001 certified companies. Beyond this global database, some Registrars provide a database of their customers on their own websites, it is recommended to try their websites to find a list of ISO 9001 registered companies.


IAF CertSearch – *Note that this database only includes certifications submitted by Certification Bodies, and may not include ALL ISO 9001 certified companies.
