You must have a User Center account.
And as mentioned in our Certification FAQ:
It is important that the email address used when registering for an exam is the email address associated to your User Center profile. This ensures that all certifications are reflected within the User Center and the e-certificate can be downloaded via the account.
Please email certification@checkpoint.com once you have a UC account and let us know when you passed the exam and what email is on your Pearson Vue account.
Thanks,
Tug
