The name of the .biz extension is a short form of the word business, and it tells visitors that the site is about commerce. It was one of the first extensions created to relieve the crowded .com zone, and it is still a practical option for small companies.

A short history
By the end of the 1990s, the .com, .net and .org zones were filling up fast, and the internet community decided to add new generic extensions. In 2000 a group of new domains was approved, and .biz was one of them, together with .info and .name. It was delegated in 2001 and opened to the public that same year. The idea was simple: give businesses a second place where short names could still be found.
Who runs it
For many years the registry belonged to Neustar. In 2020 its registry business, including .biz, was taken over by GoDaddy Registry. Registrars sell the names, and the registry maintains the central database and the name servers of the zone. DNSSEC is supported, which lets you protect your DNS answers from forgery.
Rules in practice
- Intended use: the extension is meant for bona fide business or commercial use. The registry has a dispute process for names used in bad faith.
- Who can register: in practice, anyone worldwide can order a name.
- Technical rules: up to 63 characters with letters, digits and hyphens; internationalised names are supported.
- Periods: registrations run from one to ten years.
Who uses .biz
- Small companies and freelancers who could not get their name in .com.
- Local businesses such as repair shops, studios and consultants.
- Additional addresses for campaigns or business directories.
- Companies that protect their brand by registering several extensions.
Strengths
The extension is clear in meaning and understandable in many languages. Short and exact names are easier to find than in .com, prices are usually moderate, and registration is simple.
Weaknesses
- Reputation: in the past the zone was used for spam, and some visitors and mail filters are more careful with it. A clean history and proper e-mail setup solve most problems.
- Less recognition than .com: some users may mistype the ending.
- Perceived seriousness: large brands rarely use it as the main address.
Tips before you register
- Check the name in .com too, and register both if the brand is important.
- Set SPF, DKIM and DMARC records before sending mail from the domain, because filters check new addresses carefully.
- Use a business e-mail address on the domain in your contacts, not a free mailbox.
- Enable auto-renewal and domain privacy where it is available.
.biz and search engines
Search engines do not rank a site higher or lower because of the extension. Quality content, speed and links matter. Do not expect a .biz name to help by itself, but a short, clear name can improve how people remember and share your address.
Frequently asked questions
Can an individual register .biz? Yes, but the name must be used for business purposes.
Is .biz the same as .com? No. They are different zones with different registries. A name free in one may be taken in the other.
Can I move my .biz domain to another registrar? Yes, using an authorisation code once the domain is not locked and is old enough to transfer.
