What is an IDN variant?
An Internationalized Domain Name (IDN) variant is an alternative form of the domain name. The most common example is if you register a Chinese domain name. Chinese has two scripts for the same character, simplified and traditional. Someone may have already registered the simplifed version of a domain, preventing you from registering the traditional version.
Unfortunately, due to the current design of Verisign, the central registry for .COM, .NET, .CC, and .TV, we cannot check if a variant exists ahead of time. We can only try to register the domain and if a variant exists, we get an error message (though sometimes you will see a variant error message in our search results if we received this error on that same domain name recently). Then we automatically give you an account credit for any domains we could not register.
