Purchasers wishing to confirm the validity of an accredited certification should refer in the first instance to the Certification Body shown on the certificate. The IAF website does not list accredited Certification Bodies. If the address or website of the Certification Body is unknown, this can be found from an internet search or from the Accreditation Body whose Mark should also be found on the certificate.

The address or website of the relevant Accreditation Body can be found in Recognized ABs. Clicking on the Accreditation Body’s name on their entry page will link directly to the website where information on the Certification Bodies accredited by that Accreditation Body should be available.
