The full form of .BIZ is Business

.biz is a generic top-level domain (gTLD) in the Domain Name System of the Internet. It is intended for registration of domains to be used by businesses. The name is a phonetic spelling of the first syllable of business.

The biz TLD was created to relieve some of the demand for domain names in the com top-level domain, and to provide an alternative for businesses whose preferred domain name in com had already been registered by another party. There are no specific legal or geographic qualifications to register a biz domain name, except that it must be for “bona fide business or commercial use.” It was created in 2001 along with several other domains as the first batch of new gTLDs approved by ICANN in the expansion of the Domain Name System following the increased interest in internet commerce in the late 1990s. The TLD is administered by GoDaddy and registrations are processed via accredited registrars.
