# Contact Types

System and Space Contact Types

When working with Contacts is is important to understand the differences in Contact type and how that affects where Contacts will be shown throughout the system.

***

There are 2 types of contact:

#### System Contacts

* These contacts are created by an administrator. 
* They appear in the system contacts list. 
* They can be assigned to any Space by the administrator.
* They will only appear in spaces they have been assigned. 

#### Space Contacts 

* These contacts can be created by any Space member.
* They do not appear in the system contacts list.
* They exist only in the Space where they were created.

Tip: When assigning system contacts to spaces you may want a contact to appear in ALL spaces.

In this the scenario the system contact can be marked as a *global* contact. 

They will then automatically appear in **all** current and future spaces without any explicit assignment.
