The biz domain name extension, or Top Level Domain (TLD), is meant to be used for commercial or business purposes. The biz registry has issued guidelines that biz domain names are not intended for wholly personal or non-commercial purposes.

 

The biz names can only be used for a bona fide business or commercial use. Registering a domain name solely for the purposes of (1) selling, trading or leasing the domain name for compensation, or (2) the unsolicited offering to sell, trade or lease the domain name for compensation does not constitute a "bona fide business or commercial use" of that domain name.
