The .ag extension is the country-code domain of Antigua and Barbuda, a twin-island nation in the eastern Caribbean. Hotels, yacht charter companies, local shops and firms that serve customers on the islands use it to show where they are based. English is the official language, so the zone suits English-language sites well. Use the availability form that follows this text to see whether your name in .ag is still free.

A short history
The .ag zone grew as local businesses moved online. At first it was used mainly by organisations with an international connection. Over time, guesthouses, restaurants, consultants and online shops began to register names of their own, and the zone became part of everyday business on the islands and for companies that serve the wider Caribbean.
Who runs it
A national registry keeps the database of .ag names and sets the registration rules. Customers buy names through registrars, which send the orders on to the registry. The registry's current published terms are the reference for holder eligibility, documents and renewal, and they can change, so read them before you pay.
Rules in practice
- Eligibility: conditions on holders may apply and can depend on where the holder is located, so check them first.
- Contact details: the holder information must be accurate and kept up to date.
- Characters: names use letters, digits and hyphens, within the length limits of the registry.
- Renewal: a lapsed name may be picked up by another customer, so keep the expiry date in view.
Who uses .ag
- Hotels, villas and guesthouses that welcome visitors to the islands and their beaches.
- Yacht charter companies, marine services and sailing groups.
- Shops, restaurants and service providers with customers in the country.
- Companies abroad that work with clients in the Caribbean and want a regional signal.
Strengths
- The ending links the site to Antigua and Barbuda at a glance, which helps local visitors recognise it.
- The name is short, which is useful on a boat name board, a menu or a printed brochure.
- The zone suits English-language content, since English is the official language.
Things to keep in mind
- Outside the country, the letters are often read as the word agriculture or as AG, the company form used in German-speaking countries, so the ending may need a short explanation.
- The zone points to one country, so a business with an international customer base may also need a generic address.
- Visitors from abroad may type .com out of habit, so print the full address on all materials.
- Popular short names may already be registered, so prepare alternatives.
Tips before you register
- Check the name in .com and decide whether you need both addresses.
- Enter the holder details exactly as they appear in your company or personal records.
- Publish clear contact details, opening hours or booking information on the site from the start.
- Set up SPF, DKIM and DMARC records before you send e-mail or newsletters from the domain.
- Enable two-factor login on the registrar account and keep the recovery details up to date.
Frequently asked questions
Do I need to be based in Antigua and Barbuda to register .ag? Conditions for holders may apply and can depend on your situation. Check the current terms at the time of the order.
Does .ag help a Caribbean tourism site rank in search? It is one signal of location. Clear content, accurate listings and fast pages usually matter more.
