Registrar Contact Updates

Depending on the request, changes to registrar contact information can be made in several ways:

Primary Contact Updates

Changes to the Primary Contact or Secondary Contact can be submitted by completing the Registrar Primary Contact Update Form [PDF, 184 KB] and emailing it to globalsupport@icann.org.

ICANN-accredited registrars are required to provide ICANN with accurate and current Primary Contact information. Registrars on the 2013 Registrar Accreditation Agreement (RAA) must notify ICANN of changes to Primary Contact details within five (5) days of the change.

Additional Contact Updates

Changes to additional contacts can be submitted by completing the Registrar Contact Update Form [PDF, 212 KB] and emailing it to globalsupport@icann.org.

Registrar Information Specification Updates

ICANN-accredited registrars under the 2013 Registrar Accreditation Agreement (RAA) must notify ICANN of changes to information contained in the Registrar Information Specification (RIS) within 5 days of the change.

Applicable RIS updates should be emailed to registrarupdates@icann.org. For your convenience, a spreadsheet [XLSX, 142 KB] for providing the information in the RIS is available for download.

Naming Services portal Access

The registrar's Primary Contact is automatically credentialed for access to the Naming Services portal. If you would like additional contacts credentialed for access, you may indicate so on the Registrar Primary Contact Update Form or Registrar Contact Update Form by checking the appropriate box(es). To provide access to other individuals not listed on either form, the registrar Primary Contact may do so by emailing its request to globalsupport@icann.org from its credentialed email address.

Please be advised that any credentialed user added to your account will have full Naming Services portal functionality for the credentialed account. For further details regarding the Naming Services portal and user access, please refer to Naming Services portal for Registrars on icann.org and the user guide.

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""icann.org"" is not an IDN."
