Finding your Server ID
The Server ID is an identifier for your Jira server. When creating a Jira license on my.atlassian.com, you may be prompted to enter the Server ID. You can locate your Server ID on the System info page.
For all of the following procedures, you must be logged in as a user with the Jira system administrator global permissions.
If your license has expired and you cannot find the server ID, go to Pricing, billing & licensing help and ask to extend your trial.
- In the upper-right corner of the screen, select Administration
> System. 
Under the System support (the left-side panel), select System info. The Server ID is displayed in the Jira Info section of the page.
Only admins with global permissions can access System info. If you don't see this section, ask your Jira admins to grant you access or check the Server ID.
Jira setup wizard
If you are installing Jira for the first time, you can view your Server ID on the Specify your license key screen in the Jira setup wizard. You'll see this page if you choose to perform a custom install, or if your server is not connected to the Internet.
