A domain name must not, at the time of registration

  • correspond to another protected name or trademark at the time of registration unless the domain name holder can provide an acceptable justification for its registration
  • resemble another protected name or trademark if it is registered with the apparent intent of gaining unfair advantage or causing harm.

 

Allowed characters in a domain name

The intermediary must advise its customers about the characters
, which are the letters a-z and the numbers 0-9, allowed in domain names. Other permitted
characters include the national characters å, ä and ö and the Sámi language characters of
spoken in Finland, as well as the hyphen-minus sign. When marketing and brokering domain names
, brokers must take into account the restrictions on domain names containing national characters. Customers applying for and considering a domain name should be aware of the technical limitations of domain names containing national characters. In particular, customers should be aware of the possible need to apply for both
domain names with national characters and corresponding domain names without national characters, such as ääkkönen.fi and aakkonen.fi.
The use of characters outside the Latin alphabet is made possible by the punycode, also known as ACE (ASCII Compatible Encoding). The name server system understands a domain name containing national characters if it is technically defined in ACE format. For example, ääkkönen.fi is in ACE format: xn--kknen-fraa=0m.fi. There are numerous websites offering conversion tools. Such a tool can also be found on the website of the Finnish Transport and Communications Agency.
