Things to know about choosing a domain name.
In general, only the following characters may be used in a domain name:
- Letters a through z (no accents of any kind will be accepted). Note that domain names are not case sensitive. This means there will be no distinction made between upper case letters and lower case letters (A = a);
- The numbers 0, 1, 2, 3, 4, 5, 6, 7, 8 and/or 9
- The hyphen character
There are limits on how you can use hyphens:
- A hyphen cannot be used to start or end a domain name
- Two or more hyphens cannot be in consecutive positions
Domain names must:
- Be at least 2 or 3 characters long, depending on the namespace, EXCLUDING the extension(or namespace).
- Be no more than 63 characters EXCLUDING the namespace
- Contain only letters, digits, and hyphens.
- Not start or end with a hyphens.
