Successful Candidate Register

To verify a certificate use the search function below. 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 your certificate issuer. Individuals that obtained an ISTQB® certification before January 2017 may not yet be listed. Please contact the certification body (ISTQB® Member Board or Exam Provider) who issued your certificate for information on how to be added (note: terms and conditions may vary by Board/ Exam Provider).

If you would like to withdraw or amend your information from the register please contact the Member Board or the Exam Provider who issued your certificate.
