Composition of domain names and
special exception rules for .biz domains

Not every domain name can actually be registered, since some names are not allowed for registration as a matter of principle. A designated domain name has to meet the following conditions.
  • Domain names may only consist of the letters from »a« to »z«, the digits »0« to »9«, and the hyphen. In addition to this, the use of the german umlaut characters »ä«, »ö« and »ü« is also permitted since October 12th, 2004. (For more information on this topic, please refer to the IDN page.)
  • Domain names must consist of more than two characters, and they may not be longer than 63 characters. This is also true for the punycode notation in the case of Internationalized Domain Names. You can use our handy conversion tool to find out the punycode notation of a domain name with special characters.
  • Domain names may neither start nor end with a hyphen.
  • Domain names may not include a hyphen as the third or fourth character. For example the registration of »xn--xeno.biz« is not possible.
  • The domain name may not be listed in one of the lists of exceptions below.
