The registry for the .AR ccTLD has passed identification rules for registrants for existing and new domains.
All current registrants of .AR domain names must make sure the whois info including its name, address, telephone number fax number is up to date and accurate, and the e-mail address listed on the registration must be valid and working.
In addition, registrants must provide either their tax identification code (Código Único de Identificación Tributaria, or CUIT) or their national identity document number (Documento Nacional de Identidad, or DNI). Thus, any entity which has registered a domain name under a fake name or company must update the domain name ownership details before the given deadline.
Failure to update any registrant information by May 31 2010 will result in the cancellation of the registrant in NIC Argentina’s database, along with the cancellation of any associated domain names on June 1, 2010.
The .AR registry is just one of several ccTLD registry’s that have announced identification requirements.
