Applying for sunrise applications is a little different than registering normal domain names. In most cases you will need to prove you are the legitimate owner of a trademark using a SMD file that can be obtained through the Trademark Clearinghouse if your brand is registered there.
Follow these steps to apply for a domain in Sunrise:
Log in to the registrar console
Locate the "Launch phase registration" link
Then locate the extension you are trying to register your domain in and click the extension.
If the TLD is configured to require trademark verification, you will be asked to upload an SMD file. For. TLD's not requiring trademark verification this step is omitted.
On the following screen submit your contact info and the domains you would like to register and click "submit SMD request"
