The .tf extension is the country-code domain of the French Southern Territories, a French overseas territory made up of remote islands and land areas in the southern Indian Ocean. The territory has no permanent population, although scientific stations are staffed by researchers and support teams. Because the zone is much less familiar than the major endings, a name in .tf tends to suit a narrow audience. Check the availability form at the end of this paragraph to see whether your name in .tf is still available.

A short history
The territory is known mainly for its research stations, which support work in fields such as climate, biology and geophysics. Access is limited, and the people who spend time there are mostly scientists, technicians and support staff. The national code was assigned as the territory became part of the global internet, and the zone is used by a small number of organisations connected with the territory.
Who runs it
The zone is run by a national registry that maintains the central database and sets the registration rules. Registrars sell names to customers and pass orders to the registry. Because the terms come from the registry, read the current conditions for holders, contact details and renewal, and do not treat any summary, including this one, as a replacement for them.
Rules in practice
- Holder conditions: the registry may set rules on who can register a .tf name, and these may differ from those of open zones.
- Contact details: holder information must be accurate, and the registry may request confirmation.
- Characters: names use letters, digits and hyphens, subject to the registry's length rules.
- Renewal: set the reminder early and make sure more than one person knows the expiry date.
Who uses .tf
- Research teams, universities and scientific projects that work on or around the territory.
- Organisations that publish public information about the islands' science and nature.
- Suppliers and logistics firms that work with research programmes in the region.
- Writers and enthusiasts who document the territory's history and wildlife.
Strengths
- The ending points clearly to a French overseas territory in the Indian Ocean, which suits projects with that focus.
- The two-letter code is short and easy to print on a poster, a report or a project badge.
- A name tied to a remote territory can be easy to remember for a narrow audience.
Things to keep in mind
- The zone is less familiar than the major endings, so visitors may not recognise it, and the full address should be written out clearly.
- With no permanent population, a .tf site suits a specialised audience better than a broad consumer market.
- Registration terms are set by the registry and can change, so check them directly before you decide.
- The zone's rules may differ from those of .fr, which many French-speaking readers know better.
Tips before you register
- Check the name in .com and in the national zone of the organisation's home country, if that is different.
- Use the exact organisation name in the holder details, matching the official documents.
- Describe the project on the first page, so that visitors who do not know the territory understand the site.
- Set up SPF, DKIM and DMARC records before the domain sends e-mail to partners.
- Store the registrar login safely and name a second contact who knows the renewal process.
Frequently asked questions
Can anyone register a .tf name? Conditions can apply, and they may differ from those of open zones, so check the registry's current rules before you order.
Does .tf help a site appear in search results? It is one geographic signal, but the content, the authors and the sources of a site matter far more.
Is .tf a good choice for a science blog? It can suit a project focused on the territory. For a broader science blog, a descriptive name may be easier for readers to find.
