Registry operators planning to offer a modification to an existing registry service or a new registry service must submit a request for ICANN approval pursuant to the Registry Services Evaluation Policy (RSEP). The definition of a registry service is provided in the page linked above.

In some cases, an amendment to the registry agreement between ICANN and the registry operator may be required to implement the new or modified service.  Below you will find a list of commonly requested registry services, a brief description of each service, and a link to the standard contractual language for each. This page will be updated from time to time with additional amendment templates for commonly requested services.
