The .fi extension is the country-code domain of Finland, a Nordic country in northern Europe with Helsinki as its capital. Finnish companies, clubs, schools and local services use it to show that they are based in Finland and that they speak to Finnish visitors. Finnish and Swedish are both official languages in the country, so a site may be written in either of them. Use the availability form just below this text to see whether your name in .fi is still free.

A short history
Finland received its national code in the early days of the internet, when universities, research institutes and technology firms were among the first organisations to go online. As Finnish businesses and public bodies built their own websites, the zone grew to cover companies of every size, from small service firms to large industrial and technology groups. Today .fi is the usual address for a Finnish business, and it has become a normal part of everyday online life in the country.
Who runs it
The zone is managed by a national registry that publishes its own rules on holders, names and registrations. Registrars sell .fi names to customers and send the orders to the registry, which keeps the central database and the technical records of the zone. Because the rules come from the national registry, they are the reference point for any question about eligibility, holder data or transfers, and they can be updated over time.
Rules in practice
- Holder conditions: the registry sets rules on who may hold a .fi name, so read the current conditions before you order.
- Contact details: the holder data must be complete and correct, and the registry may ask for it to be confirmed.
- Letters and length: names use letters, digits and hyphens, and a single label can be up to 63 characters long.
- Finnish letters: names with the letters ä, ö and å may be possible as internationalised names, depending on the registry rules.
Who uses .fi
- Companies of every size, from sole traders to national firms.
- Restaurants, hotels, shops and service providers in Finnish towns and cities.
- Sports clubs, schools, associations and community groups with a Finnish audience.
- Tour operators that promote Finland, including travel companies that offer trips to Lapland.
Strengths
- The ending gives a clear signal of Finnish origin, and Finnish users recognise it at a glance.
- Search engines can treat a country-code ending as one hint about the audience, so a Finnish-language site may match local searches well.
- The name is short and familiar on vehicles, menus and printed materials across the country.
Things to keep in mind
- The zone suits a Finnish audience best, so an export business may also need a generic address.
- Finnish visitors often expect Finnish-language content, and an English-only site may feel less natural to them.
- Many short and descriptive names are already taken, so prepare two or three alternatives.
- Rules for holders can change, so keep your registration details current.
Tips before you register
- Check the same name in .com and decide whether a second address is worth it.
- Enter the company details exactly as they appear in the official business register.
- Prepare Finnish content and clear contact and company information for the website.
- Host the site close to Finnish visitors so that pages load quickly.
- Set up SPF, DKIM and DMARC records before you use the domain for e-mail.
Frequently asked questions
Do I need a Finnish company to register .fi? The registry sets conditions for holders, and they decide who may register a name. Read the current rules before you order.
Can an English-language site use .fi? Yes. The ending says where the business is based, not which language the site uses, but Finnish visitors will still appreciate some Finnish content.
Can I use the letters ä, ö and å in a .fi name? It may be possible through internationalised names. Test how the address displays in several browsers before you print it on materials.
