What characters can I use in my domain name?
A domain name can contain the numbers 0-9, the letters a-z and the hyphen character ("-"). Note however that domain names cannot begin or end with a hyphen.
A domain name can contain up to 67 characters, although some domain registrars have still not reconfigured their services to accommodate these longer domain names (domain names used to be limited to 26 characters until mid-1999)
This 67 character limit includes the "." (dot) and the top level domain. So in the case of a ".com" name, for instance, you'll be able to specify up to 63 characters.
Some top domains from specific countries have additional limitations on length and on the number of characters in a domain. Some even specify a minimum length for a domain name, such as 3 characters or more. For the specific rules of each of the over 200 top-level domains, you'll have to read the small print when you register a domain.
