Jira comes with standard, built-in fields, like “Summary”, “Description”, and “Components” but you can also create additional Custom Fields to track more data.
Your instance starts out with 8-30 fields, depending on whether you have Cloud or Server. For example, Jira Server 7.7.1 comes with 8 custom fields. Installing Jira Service Desk on top of Jira Server adds 6 additional fields. More fields can be created by Jira, by application administrators, or by add-ons, plugins, and applications.
So how do you distinguish the standard fields from the ones created by applications and admins? Use this baseline list from a clean Jira install.
