You noticed an end user in Zendesk Support that you do not recognize. How can a user be created in Zendesk?
There are several ways that a user record can be created in Zendesk. See the information in this table:
|Email to a support address*||When you receive an email at one of your support addresses, Support automatically creates a user record if one does not exist already.|
When a customer initiates a chat or fills out the offline message form, Zendesk Chat creates a new user record, either using the email address the user provided or creating a generic Visitor record.
|Incoming call||When you receive a call from a new number, Zendesk Talk creates a Caller [Number] user record.|
|Facebook/Twitter||If you have a social media integration with Facebook or Twitter, a message or tweet from a customer creates a new user record if one doesn't exist already.|
|Manual registration via Help Center*||A user can manually create an account by going to your Help Center and signing up or submitting a request.|
|Manual addition by an agent in Zendesk||An agent with the appropriate role can manually create a new user via the agent interface.|
|User import||You can bulk import users via a CSV file.|
|CC on an email||If one of your users replies to a ticket or creates a ticket and CCs another email address, Support creates a new user for that email identity if one does not exist already. This happens provided the "Anybody can submit tickets" setting is enabled.|
|API request||A user can be created either via a direct request to the users API endpoint, or via a ticket creation API call that includes a new user.|
|SSO user provisioning||Depending on your SSO solution, a user record is created the first time a user visits or attempts to sign into your Help Center.|
|Salesforce integration||If you have configured Salesforce Contact/Lead to Zendesk user sync, Salesforce automatically creates user records whenever a sync is triggered.|
|Ticket sharing||When an agent at a sharing partner site shares a ticket to your Zendesk instance for the first time, Support creates a dummy user record for any users who have commented on that ticket.|
