Where can I find my Zendesk subdomain?
Your subdomain is its unique identifier. There are two ways to find it:
Check your URL
If you have not enabled the host-mapping feature in Zendesk Support, your subdomain can be identified from the account's URL: https://[yoursubdomain].zendesk.com
Request an Email
You can also get a list of Zendesk subdomains that your email address is associated with from the Remind me page where you will be presented with this prompt:
Type your email address and you will receive your subdomain via email.
If you have troubles receiving the email, make sure to check the spam folder of your inbox. Alternatively, this means that there is no account with the email address chosen.
