The restrictions imposed on domains vary depending on what extension you are registering and what country the domain is associated with.

Domains can be formed using only use letters and numbers from the ASCII set of characters e.g. (a-z) (A-Z) (0-9). Hyphens are also allowed but must be surrounded by characters, therefore not at the beginning or end of the domain. You're not allowed to use special characters (like '#*%') and spaces cannot be used.

General Rules

  • Your domain must be unique, i.e. a domain name that is not already in use. You can check if the name has already been taken through our domain name search. 
  • .com .net .org and .info domain names cannot exceed 67 characters.
  • .info and .biz must have at least 3 characters not including .info and .biz
  • Other domain names cannot exceed 22 characters not including the extension. 
  • Domain names are not case sensitive.
  • 2 letter domains are not allowed.

Note: When looking for a domain name you should always compare the renewal price and not just look at the first year offer.
