Issue:
My name is not displayed on my Udemy Certificate of Completion. Only a user number is displayed on the Udemy Certificate .
Cause:
Udemy integration can use anonymous authentication, so it is expected for a unique User Number to appear on the certificate instead of the user's name in some cases.
Resolution:
Your organization has chosen to anonymize its users within Udemy so any certification that is completed will receive a user number instead. The user number displayed on the certificate is unique to you.
Please see an image example below (the number is blocked out to keep user privacy):
