List of ISO 9000 Registered Companies

Independent Association of Accredited Registrars (IAAR) publishes a list but it is not guaranteed to be complete.

It is difficult to maintain a list of ISO 9001 registered companies because:

  • There is not a single body that registers organizations worldwide. ISO does not register people, an accredited Registrar does. (List Below). The ANAB provides more info on the levels of oversight for ISO certification.
  • It is only a 3 year certification - companies may switch registrars after 3 years and this becomes increasingly difficult to track.
  • Companies may be registered by several organizations for different standards
  • It costs money to maintain a list like this.
  • Each company that is registered must go through a rigorous initial process including creating a complete and functioning quality management system or QMS, which they may not actually complete in full

To understand the relationship, see: Who is eligible to grant ISO 9001 Certification? If you would like to learn more general information, including ISO training, you can explore our what is ISO link.
