ISTQB Certified Tester List can be found at ISTQB “Successful Candidate Register” (link). 

It is a new central register of successful candidates that is available on the ISTQB® website from June 2017. The Successful Candidate Register will list individuals who pass an ISTQB® certification examination (at all levels and across all modules) and who have given their consent to be included.

To verify a certificate use the search function. Certificate holders meeting the search criteria will be listed with an anonymized certificate number meaning some digits are replaced by ***. This feature allows ISTQB® to protect the certificate number from being misused but gives enough information to verify a certificate number that an individual has provided.

Inclusion is voluntary so not all certification holders may be included. The register is updated regularly but please allow some time for your details to appear – if you have any concerns please contact VTB . Individuals holding an ISTQB® certification before the launch of the register may not yet be listed please contact the certification board who issued your certificate for information on how to be added (note: terms and conditions may vary by Board).
