Can I get my old subdomain back?

Can I use an existing domain for my account?

No. If your desired subdomain is in use, you receive an error message when you claim the name: That subdomain is taken, but we suggested a new one above.

You can't use the subdomain if another company uses that subdomain. Zendesk doesn't allow two accounts to have the same name because your subdomain is your unique account identifier.

Note: As of November 2022, Zendesk can no longer process requests to change the subdomain on a customer's behalf. However, if you or a colleague used that subdomain for an expired trial or a canceled account, contact Zendesk Customer Support for further help.
