How do I subscribe to a mailing list?

  • Go to the ITU-T Electronic Registration and Subscription Service page.
  • Click on the “Login” button and identify yourself with your TIES username and password, or your Guest account username and password.
  • Once logged on your services page, click on the “Subscription” button.
  • Expand the tree view (click on ) to see all mailing lists to which you can subscribe.

    Note: Guest accounts will only see public mailing lists.
  • Check the lists that you want to subscribe to and click the “Submit” button.
  • Shortly afterwards you will receive an email confirmation to your default email address.
  • The subscription procedure might take up to 1 hour to be fully completed.
  • Most of the ITU-T mailing lists are reserved to ITU-T members only. If you want to subscribe to a specific mailing list as a guest, you should send a request to the concerned Study Group secretariat.
  • Adding email addresses not associated with an account (TIES or Guest) is no longer allowed.
