The .bg extension is the country-code domain of Bulgaria, a country in south-eastern Europe with a coastline on the Black Sea. Bulgarian companies, schools, tourism operators and local services use it to show that they are based in Bulgaria and that they serve Bulgarian visitors and customers. The capital is Sofia, and the official language is Bulgarian. Use the availability form just below this text to see whether your name in .bg is still free.

A short history
Bulgaria received its national code in the early years of the internet, when the network was used mainly by universities, research institutes and technology groups. As Bulgarian businesses moved online, the zone grew to cover shops, service firms, media outlets and organisations of many kinds. Today .bg is a familiar ending across the country, and it remains a common choice for businesses that want an address rooted in their home market.
Who runs it
The .bg zone is administered by the national registry, which keeps the central database of names and publishes the rules for registration and for the holders of domains. Accredited registrars sell names to customers and send the orders to the registry. Because the registry sets the conditions, its published terms are the reference point for any question about eligibility, holder data or renewal, and those terms can change over time.
Rules in practice
- Holder conditions: the registry sets rules on who may hold a .bg name, so read the current terms before you pay for a registration.
- Contact data: the holder details must be accurate, and they may be checked when the registry asks for confirmation.
- Length and characters: a label uses letters, digits and hyphens, and can be up to 63 characters long, which is the general limit for a single label in the domain name system.
- Renewal: put the expiry date in your calendar and enable automatic renewal, because a lapsed name can be registered by someone else.
Who uses .bg
- Bulgarian companies of every size, from sole traders to larger firms.
- Hotels, guest houses and restaurants on the Black Sea coast and in the mountain resorts.
- Software, outsourcing and other technology firms that work with Bulgarian clients.
- Schools, clubs, cultural projects and local community groups with a Bulgarian audience.
Strengths
- The ending shows a clear Bulgarian base, which helps local visitors recognise the business at once.
- Search engines can treat a country-code ending as one signal of the intended audience, so Bulgarian-language content may match local searches well.
- The zone is short and easy to type, and it works well on signs, menus, vehicles and business cards.
Things to keep in mind
- A .bg name points to Bulgaria, so a business with mostly overseas customers may also want a generic address.
- Good short names are often taken, so prepare two or three alternatives before you start.
- Bulgarian is written in Cyrillic, while a domain name uses Latin letters. Decide on one transliteration of your name and use it everywhere.
- Registry terms can change, so an older registration may need updated holder details later.
Tips before you register
- Check the same name in .com and decide whether you need both addresses.
- Enter the company and holder details exactly as they appear in your official records.
- Prepare Bulgarian content, clear contact pages and the company information that Bulgarian websites are expected to publish.
- Set SPF, DKIM and DMARC records before the domain sends any e-mail.
- Turn on auto-renewal and protect the registrar account with two-factor login.
Frequently asked questions
Do I have to live in Bulgaria to register a .bg name? Holder conditions apply, and they can depend on your situation, so check the current terms at the time of the order.
Does .bg help a site appear in Bulgarian search results? It is one useful geographic signal. Clear Bulgarian content, fast pages and relevant local links usually matter more.
Can I use Cyrillic letters in a .bg name? Internationalised names may be possible under the registry rules. Test how the address displays in several browsers before you print it on materials.
