By default your Zendesk Support ticket ID will start at 1, then increase. If you want your ticket IDs to begin at another number, you can manually set the starting number for the ticket ID counter. This change does not affect any current tickets existing in your account, only new tickets moving forward.
- Click the Admin icon () in the sidebar, then select Settings > Tickets.
- In Ticket IDs, enter a new number.
Note: The value must be greater than your current highest ticket ID number and can be no longer than nine digits. For example, if you currently have 1000 tickets, you must start numbering from 1001 or higher.
- Click Save tab.
