Welcome to the Trademark Clearinghouse Database (TMDB) web client

As part of ICANN’s commitment to security and stability, ICANN has enhanced the security configuration on the Trademark Database (TMDB) interfaces. These changes are effective since 10 December 2018.

If you have questions, please contact ICANN’s Global Support Center by email.

The Trademark Clearinghouse Database (TMDB) system serves as the central database to provide information to Registries and Registrars supporting the Sunrise and Claims services.

The TMDB system web client enables Registries and Registrars to access the Clearinghouse Database (TMDB) system. Only Registries and Registrars that are authorised by ICANN are authorised to access the TMDB system.

Registry:

As a Registry, you own a Top Level Domain (TLD) and can accept Domain Name registrations from Registrars; maintaining the central Database of Registered Domains. If you are authorized as a Registry, the TMDB web client allows you to:
  • Configure and test your connections with the TMDB
  • Retrieve the SMD Revocation List
  • Retrieve the DNL List
  • Submit a LORDN File
  • Retrieve a LORDN Log File

Registrar:

As a Registrar, you can register Domain Names with the Registry on behalf of the Registrant. If you are authorized as a Registrar, the TMDB web client allows you to:
  • Configure and test your connections with the TMDB
  • Retrieve the SMD Revocation List
  • Retrieve CNIS files
