Why does my customer's name appear incomplete in Support?

Question

Why does the name of an end user appear without their full name after their creation in Zendesk Support? 

Answer

The name of a customer may appear incomplete if the user was not created via email, but rather by an agent who manually added the user as the requester of a new ticket.

When the agent adds the user's email in the Requester field, the first portion of the email is used to populate the user's name when the user is created. For example, if the email is [e-mail], the new user's name is "watson".

Later, admins or agents with the appropriate permissions can update the user's profile to include the full name. For more information, see the article: Adding end users.
