Registry Agreement Amendment Templates for Commonly Requested Registry Services

Please note that the English language version of all translated content and documents are the official versions and that translations in other languages are for informational purposes only.

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.

Bulk Transfer After Partial Portfolio Acquisition (BTAPPA) [PDF, 45 KB]

This service permits registry operators to offer to registrars a service where an ICANN-accredited registrar purchases a portion but not all of another ICANN-accredited registrar's domain name portfolio in the top-level domain (TLD).

Internationalized Domain Names (IDNs)

This service permits registry operators to offer Internationalized Domain Names (IDNs), non-ASCII domain names at the second- or lower-levels. Registry operators are encouraged to use standardized, pre-approved Reference Label Generation Rules (LGR) tables.

Registration Validation per Applicable Law

This service permits registry operators to perform registration validation to comply with applicable law in a given jurisdiction. Some registries may additionally request approval to use a supplementary registration proxy in conjunction with registration validation.

Registry Lock [PDF, 40 KB]

This service helps protect against inadvertent transfers, modifications to or deletions of domain name registration data by allowing an authorized representative from the sponsoring registrar to request the activation or deactivation of certain EPP statuses.

Domain Name System
Internationalized Domain Name ,IDN,"IDNs are domain names that include characters used in the local representation of languages that are not written with the twenty-six letters of the basic Latin alphabet ""a-z"". An IDN can contain Latin letters with diacritical marks, as required by many European languages, or may consist of characters from non-Latin scripts such as Arabic or Chinese. Many languages also use other types of digits than the European ""0-9"". The basic Latin alphabet together with the European-Arabic digits are, for the purpose of domain names, termed ""ASCII characters"" (ASCII = American Standard Code for Information Interchange). These are also included in the broader range of ""Unicode characters"" that provides the basis for IDNs. The ""hostname rule"" requires that all domain names of the type under consideration here are stored in the DNS using only the ASCII characters listed above, with the one further addition of the hyphen ""-"". The Unicode form of an IDN therefore requires special encoding before it is entered into the DNS. The following terminology is used when distinguishing between these forms: A domain name consists of a series of ""labels"" (separated by ""dots""). The ASCII form of an IDN label is termed an ""A-label"". All operations defined in the DNS protocol use A-labels exclusively. The Unicode form, which a user expects to be displayed, is termed a ""U-label"". The difference may be illustrated with the Hindi word for ""test"" — परीका — appearing here as a U-label would (in the Devanagari script). A special form of ""ASCII compatible encoding"" (abbreviated ACE) is applied to this to produce the corresponding A-label: xn--11b5bs1di. A domain name that only includes ASCII letters, digits, and hyphens is termed an ""LDH label"". Although the definitions of A-labels and LDH-labels overlap, a name consisting exclusively of LDH labels, such as"""" is not an IDN."
