By default, your Zendesk Support ticket ID starts at 1 and increases. To start your ticket IDs at a different number, admins and agents in custom roles with permission to manage ticket settings can manually set the starting number. This change doesn't affect any existing tickets in your account; it only affects new tickets moving forward.
To change the ticket ID starting number
- In Admin Center, click
Objects and rules in the sidebar, then select Tickets > Settings. - Click Assignments and notifications to expand it.
- In the Ticket IDs field, enter a new number.
You can increase your current ticket ID, but you can't decrease the number.
Changing the ticket ID starting number can't be undone.
- Click Save.
