Authenticate a Transaction

We’ve developed a single source of truth for all valid transaction certificates issued from active certification bodies from October 2022. Check if the transaction certificate you are holding is authentic by entering the required information and matching the return values. Lodge an enquiry with your certification body if you cannot find your certificate or if the return values do not match.
