After your Trademark Agent account has been verified and you have received your credentials for the production environment, you need to request your credentials for the OT&E environment. You can do this by creating a ticket in our dedicated Customer Support System, either by clicking on "GET SUPPORT" on the TMCH interface or by sending an email to support[at]trademark-clearinghouse[dot]com.

Please note that it may take up to 30 minutes before the IP address is whitelisted.
