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.
• etc.

To understand the relationship, see: Who is eligible to grant ISO 9001 Certification?
