The .do extension is the country-code domain of the Dominican Republic, which occupies the eastern part of the island of Hispaniola in the Caribbean. Spanish is the official language, and Santo Domingo is the capital. Hotels, beach resorts, schools and local businesses use .do to show their connection to the country. Use the availability form just below this text to see whether your name in .do is still free.

A short history
The national code was set up in the early days of the internet, and the zone has grown alongside tourism, education and commerce on the island. Many businesses use the ending on their websites, from beach resorts to shops in the cities. For the current rules and dates, check the operator's published information rather than older summaries.
Who runs it
The zone is managed by a registry operator that keeps the database of names and sets the rules for registration. Registrars take orders from customers and pass them to the registry. The operator's published terms cover eligibility, contact details and renewal. Because they may change, read the version in force at the time of the order.
Rules in practice
- Holder conditions: conditions on who may register a .do name can apply, so check them before you pay.
- Contact details: the holder information must be accurate, and it may be verified when the registrar asks.
- Characters: names use letters, digits and hyphens, and each label can be up to 63 characters long.
- Renewal: renew before the expiry date, because a lapsed name can be picked up by someone else.
Who uses .do
- Beach resorts, hotels and villas that welcome visitors to the coast and the cities.
- Restaurants, shops and service providers in Santo Domingo, Santiago and other towns.
- Schools, universities and sports organisations with a Dominican audience.
- Businesses and associations among the Dominican diaspora that want a clear link to the country.
Strengths
- The ending links the site to the Dominican Republic at a glance, which helps local customers recognise it.
- Spanish is the main language, so a site in Spanish fits the local audience well.
- The address is short and easy to read on a menu, a van or a shop sign.
Things to keep in mind
- Dominica, a separate island country, uses .dm. Visitors may mix up the two endings, so state the country clearly on the home page.
- The letters form the English word do, so the full address can read in an unexpected way. Check how it looks in print and on a phone.
- Good short names are often taken, so a place name or a service name can make the address easier to register.
- Conditions for holders can change, so check the current terms before you renew.
Tips before you register
- Check the name in .com and in the booking platforms you already use.
- Enter the business details exactly as they appear in the official register.
- Publish the site in Spanish, with English pages if tourists are part of your audience.
- Set up SPF, DKIM and DMARC records before you send bookings or invoices.
- Protect the registrar login with a strong password and keep the contact address current.
Frequently asked questions

Do I need to live in the Dominican Republic to register a .do name? Holder conditions can apply and may depend on your situation. Check the current terms at the time of the order.
