You can require customers to enter information, like name, phone number, or a question, by enabling the pre-chat form.
To enable the pre-chat form
- From the dashboard, select Settings > Widget.
 - Click Forms at the top of the page.
 - Next to Pre-Chat Form, click On.
 - Select the information you want end users to enter before they can start a chat, like in the example below:

 
Some of the displayed options vary depending on your settings in other areas:
- 
For the Require Phone Number option to appear, you must select Allow Phone Number under the Visitor Profile section of the same page.
 - 
For the Require Department option to appear, you have to have departments enabled. For details, see Creating agents and departments.
 
In rare situations, information required in the pre-chat form may not be passed into the chat:
- If the chat is started by a proactive trigger, the pre-chat form requirement is bypassed and chats can be created without users having to fill in their name and email address. For more information, see Why do I keep receiving chats with no customer contact information?
 - If a chat is interrupted or disconnected, pre-chat data may not be reapplied upon reconnection, including department and visitor tags.
