Domain Extensions & TLD FAQs

A domain extension (also called a TLD or top-level domain) is the suffix at the end of a domain name, such as .com, .net, or .org. You may also see them called domain endings or URL extensions. There are over 1,500 domain extensions delegated by ICANN, and our TLD search tool lets you search across 800+ of the most relevant ones instantly.

The most popular domain extensions are .com, .net, .org, .info, and .co. The .com extension accounts for roughly half of all registered domains worldwide with over 150 million registrations. Newer extensions like .io, .ai, .app, and .dev have grown rapidly in popularity, especially among technology companies and startups. Use our domain search to check availability across all of them at once.

There are over 1,500 domain extensions (TLDs) delegated by ICANN, and our tool lets you search across 800+ of the most relevant ones instantly. The number of available extensions has grown significantly since ICANN began approving new gTLDs in 2012, adding hundreds of industry-specific, geographic, and brand extensions to the original set.

Some of the cheapest domain extensions include .xyz, .online, .site, .store, and .shop, which often cost under $5 per year for the first year. Keep in mind that renewal prices are typically higher — a $1 first-year deal may renew at $30+. Classic extensions like .com ($9–$12/year) offer better long-term value. Use our extension search tool to compare prices across 20+ registrars and find the best deal for any TLD.

Google treats all domain extensions equally for ranking purposes — a .xyz site can rank just as well as a .com. However, .com domains tend to get higher click-through rates because users trust them more. Country code TLDs like .uk, .de, and .ca can boost visibility in local search results for those regions. The best SEO strategy is to choose a memorable, brandable domain name regardless of extension, then focus on quality content and backlinks. Use our domain checker to find available options across every extension.

Use our domain extension checker to search all available TLDs at once. Type any domain name and instantly see which of 800+ extensions are available, taken, premium, or for sale. You can filter results by status and compare prices across multiple registrars — all from a single search.

Domain extension and TLD (top-level domain) mean the same thing. Both refer to the last part of a domain name after the dot, such as .com or .org. The term "domain extension" is more commonly used in everyday language, while "TLD" is the technical term used by ICANN and the domain industry. You may also see them called "domain endings" or "URL extensions."

Most domain extensions are open for anyone to register, but some have restrictions. Country code TLDs like .us, .eu, and .ca may require residency or a local presence. Some industry extensions like .bank and .pharmacy require verification. Our TLD search tool shows which extensions are available for registration and where to buy them.

If your preferred .com domain is taken, you have several options. Try alternative extensions like .io, .co, .ai, or an industry-specific TLD that fits your brand. Our extension search checks 800+ TLDs simultaneously, so you can quickly find which alternatives are available. You can also explore aftermarket domains or use our domain name generator to discover creative variations.

New domain extensions (also called new gTLDs) are TLDs that ICANN has approved since 2012. These include industry-specific endings like .app, .dev, .shop, .tech, and .online, as well as brand TLDs like .google and .amazon. ICANN's next round of new gTLD applications is expected to open soon, which will add even more options. Browse our full list of domain extensions to see every available TLD.
