This form is used to modify an existing user port number assignment in the IANA Service Name and Transport Protocol Port Number Registry. This is not an application for a new service name or port number assignment.
We require that all current assignees and/or contacts listed in the registry verify the requested changes by email. We also require email confirmation(s) from every updated assignee and/or proposed contact person (if different from the current assignee or contact person).
Once these changes are verified, we will update the registry and notify you when the changes are complete. If you would like to change information for more than one assignment, please submit separate templates. Please enter NEW information in this template.
