A gTLD (generic top-level domain) is a top-level domain that is not a country code — for example, .com, .org or .app. Generic TLDs are usually global in scope, and they make up the large majority of the more than 1,500 TLDs in the IANA root zone — around 1,200 of them.
Whenever a web address ends in something that is not a two-letter country code, you are almost certainly looking at a generic TLD. .com, .net, .store, .blog — all generic. The category is broad on purpose: it covers everything from the original handful of extensions to the wave of new endings introduced in the last decade.
The cleanest way to define a gTLD is by what it is not. The TLD universe splits into a few groups, and the two you meet most are generic TLDs and country-code TLDs (ccTLDs). If it is not a country code — and not one of the rare infrastructure entries — it is generic.
What makes a TLD “generic”?
“Generic” here means not tied to a single country. A ccTLD such as .de belongs to Germany; a gTLD such as .com belongs to no nation in particular and is intended for a worldwide audience. That global reach is the defining trait.
Some gTLDs are wide open to anyone, while others are themed or restricted to a particular kind of registrant. What unites them all is that none represents a country or territory. For the head-to-head comparison with country codes, see gTLD vs ccTLD.
Generic top-level domain — any top-level domain that is not a country code, generally global in scope, spanning the original legacy extensions and the newer ones introduced through ICANN’s expansion program.
What are the sub-types of gTLD?
Not all generic TLDs are the same. It helps to sort them into a few practical sub-types, based on when they appeared and who operates them:
| Sub-type | What it is | Examples |
|---|---|---|
| Legacy / original | The early generic extensions that pre-date the modern expansion. | .com .org .net .info |
| New gTLD | Extensions delegated through ICANN’s program that began in 2012, often themed. | .app .shop .blog .xyz |
| Brand TLD | A new gTLD matching a company’s trademark, run for that brand. | .google .bmw .barclays |
| Geographic | A new gTLD naming a city or region (still generic, not a country code). | .london .nyc .berlin |
Of these, the legacy names like .com remain the most recognized, while the new gTLDs added the variety. Geographic gTLDs are worth a note: a city extension such as .london is still generic, because country codes are reserved for the two-letter ISO entries — not for cities or regions.
Where .com came from
.com was created for commercial organizations, which is what the three letters originally stood for. Those restrictions fell away long ago: today .com is open to anyone and serves as the default extension for brands worldwide.
How were the new gTLDs created?
For years, the list of generic extensions barely changed. That ended with ICANN’s New gTLD Program, which launched in 2012 and invited applications for brand-new endings. The first new gTLDs began entering the root zone around 2013 and 2014, and the available choices expanded dramatically — from a short list into many hundreds.
Each new gTLD is operated by a registry approved by ICANN and delegated by IANA into the root. That is how niche endings like .app, .dev and .shop came to exist alongside the originals. For a closer look at that expansion, see new gTLDs explained.
Generic does not always mean unrestricted
A gTLD can still carry rules. Some require you to be in a particular industry or to meet eligibility criteria set by the registry. “Generic” describes the extension’s non-country nature, not whether anyone can register it.
How do gTLDs fit among the TLD types?
Generic TLDs are the largest branch of the top-level domain system. Of the more than 1,500 TLDs in the IANA root zone, roughly 1,200 are generic, around 300 are country codes, and a small remainder are sponsored or infrastructure entries. So when you pick an extension, you are most often choosing among gTLDs.
To see how all of these pieces connect — and where each sits in the naming tree — begin with what is a TLD, then explore how the DNS hierarchy works when you are ready to go deeper.
Should you choose a new gTLD or a legacy one?
With so many generic extensions now available, the real question is usually not whether to use a gTLD but which one. The legacy names — above all .com — carry the most instant recognition and are the safe default, which is exactly why the best ones are so often already taken.
That scarcity is where the newer gTLDs earn their place. A descriptive ending such as .shop, .app or .studio can let you register a short, memorable name that matches what you do, and it tells visitors something about the site before they read a word of it. The trade-off is familiarity: a brand-new extension may need a little more explaining than a .com. Weigh memorability against recognition, check the registry’s pricing and any eligibility rules, and let the decision follow your audience.

★ Key takeaways
- A gTLD is a generic top-level domain — any TLD that is not a country code, like
.comor.app. - Sub-types include legacy, new, brand and geographic gTLDs.
- ICANN’s New gTLD Program launched in 2012, with the first delegations around 2013–2014.
- Around 1,200 of the 1,500+ TLDs in the IANA root zone are generic.
Frequently asked questions
What is a gTLD in simple terms?
A gTLD is a generic top-level domain — an extension that is not a country code. Examples include .com, .org, .net and newer names like .app and .shop. Generic TLDs are usually open to a global audience rather than tied to one nation.
What is the difference between a gTLD and a ccTLD?
A gTLD is a generic, non-country extension such as .com or .blog, generally global in scope. A ccTLD is a two-letter country-code extension such as .us or .de, tied to a specific country or territory. The split comes down to geography.
When were the new gTLDs introduced?
ICANN’s New gTLD Program launched in 2012, opening the door to hundreds of new generic extensions. The first of these new gTLDs began appearing in the root zone around 2013 and 2014, greatly expanding the range of available endings.
How many gTLDs are there?
There are approximately 1,200 generic top-level domains in the IANA root zone, the large majority of all TLDs. The figure shifts over time as new extensions are delegated and a few older ones are retired, so treat any exact number as approximate.
What is a brand TLD?
A brand TLD is a type of new gTLD that matches a company’s trademark, such as .google or .bmw. The brand owner runs the extension as its own registry, typically for its own websites rather than offering it for public registration.
