A domain extension is the ending after the dot, such as .com, .io or .us. NameBest sells generic extensions, country extensions and newer extensions, and this page lists every one we offer with its first year and renewal price. Each extension page explains who it suits and any rules its registry sets.

These are the endings people search for most. Open any of them to see its price, its registry rules and a search box limited to that extension.

Extensions fall into three groups. The group tells you who runs the registry, who may register and what rules apply.
Generic extensions, called gTLDs, are open to anyone in any country. The oldest are .com, .net and .org. They follow ICANN policies, which means the same rules on transfers, renewals and disputes apply to all of them. Choose a generic extension when you want a name that reads as global and carries no country.
Country code extensions, called ccTLDs, belong to a country or territory, such as .us for the United States or .me for Montenegro. Each country sets its own rules. Some require a local address or a connection to the country, some limit WHOIS privacy, and some are used worldwide for a meaning that has nothing to do with the country. .io is the code of the British Indian Ocean Territory, .co is Colombia and .ai is Anguilla, yet all three are widely used by tech companies.
New generic extensions, launched since 2014, describe a topic or an industry, such as .app, .dev, .shop or .xyz. They are open to anyone, follow ICANN policies like the old generics, and often have short names still free. Some come with technical rules: .app and .dev are on the HSTS preload list, so they only load over HTTPS.
05
| Extension | Rule | What it means for you |
|---|---|---|
| .ai | Minimum 2 year registration | The first payment covers 2 years |
| .app and .dev | HTTPS only | Your site needs a TLS certificate to load |
| .us | US connection required, no privacy | You confirm a US nexus and your details show in WHOIS |
| .io | Country extension of a territory | Registry rules and prices are set by its operator |
| .co | Country extension of Colombia | Open to anyone, used worldwide as company |
We show these rules in the search result and in the cart, so nothing comes as a surprise at checkout.

Start with the name, then pick the ending. If the .com is free and the price works for you, take it. If it is taken, look at the endings your audience already knows: .io and .dev for developers, .ai for AI products, .shop for stores, a country ending for a local business. Compare the renewal price, because that is what you pay every year after. For more help, read how to choose a domain name and see full price details on the domain prices page.

.com is the safest choice for most businesses because people type it by habit. When it is taken, pick an extension your audience already trusts, such as .io for software or a country ending for a local business.
Generic extensions do not give a ranking advantage over each other. Country extensions can help a site rank in that country, because search engines treat them as a local signal.
It depends on the country. Many, such as .co, .io and .me, are open to anyone. Others, such as .us, require a connection to the country. Each extension page lists its rules.
It is included on every extension whose registry allows it. A few country extensions, such as .us, do not allow privacy, and the table above shows this for each extension.
Buy the main one first. Add other extensions or typo variants only when losing them would hurt your brand, and forward them to your main site. Read should I buy all domain extensions.
