The .tt extension is the country-code domain of Trinidad and Tobago, a twin-island nation in the southern Caribbean with its capital in Port of Spain. Music groups, carnival organisers, tour operators and local firms use it to show a clear link to the islands. Find out in the availability form just below this text whether your name in .tt is still available.

A short history
The islands are known for their music, especially the steelpan, and for a carnival season that draws performers and visitors every year. The national zone grew alongside the country's businesses and cultural groups as they moved their listings and schedules online. Today the .tt name is used across tourism, the arts, food and professional services, so it reflects both island life and a wide range of work.
Who runs it
The .tt zone is run by a national registry that maintains the database of names and publishes the terms for holders. Registrars take orders from customers and send them to the registry, which keeps the central record. The published terms are the reference point for eligibility, contact details and renewal, so read the current version before you choose a name.
Rules in practice
- Holder details: the registrant's information must be accurate, and it may be verified by the registry or the registrar.
- Characters: names use letters, digits and hyphens, subject to the length limits set for the zone.
- Conditions: some zones restrict who can hold a name, so confirm whether your business or your own situation qualifies.
- Renewal: a name that expires can be released, so keep the renewal date visible to the whole team.
Who uses .tt
- Steelpan orchestras, calypso artists and event promoters that present their programmes online.
- Carnival bands, costume designers and festival organisers with an audience at home and abroad.
- Hotels, guesthouses and tour operators that serve visitors to Trinidad and Tobago.
- Restaurants, food producers, consultants and law or accounting firms serving local clients.
Strengths
- The ending shows at once that a site is linked to Trinidad and Tobago, which helps regional visitors recognise it.
- The English-speaking audience can read the site without a translation, which suits an international event or a tourism business.
- The two-letter code is short, so it fits well on tickets, posters and vehicle graphics.
Things to keep in mind
- The zone is tied to one country, so an artist or company with a global audience may also need a generic address.
- Many visitors will look for the full country name, so include Trinidad and Tobago in the site title and footer.
- Good short names are often taken, so prepare a second choice that includes a place name or an event name.
- Conditions and policies can change, so review the registration details every year.
Tips before you register
- Compare the name with .com and with the social networks you use for bookings.
- Enter the business or personal details exactly as they appear in your official documents.
- Publish event dates, contact numbers and a privacy notice before you start promoting the address.
- Set up SPF, DKIM and DMARC records before you send ticket confirmations by e-mail.
- Store the registrar login in a password manager and enable two-factor login.
Frequently asked questions
Does a .tt name require a local address? Holder conditions differ between zones, so read the current terms before you order.
Can a steelpan group use .tt for its events? Yes. The ending does not restrict subject matter, but a group based abroad should check the zone terms first.
Does .tt help a site appear in local search results? It is a useful geographic signal. Clear event information, accurate listings and genuine local links usually matter more.
