The perfect domain is just a click away: find your domain →
Every 3 letter .com domain is already registered and has been since the late 1990s, but that is only true for .com. Across the rest of the domain system there are still hundreds of unregistered 3 letter combinations you can buy at a normal registration price today, and a quick domain name search will show you which ones.

TL;DR: are there 3 letter domains available
3 letter .com domains ran out decades ago and the only way to get one now is to buy it from whoever owns it, usually for six figures. The wider domain system tells a different story. Newer extensions and some country codes still have unregistered 3 letter names sitting at standard registration prices, and a few of them are genuinely usable.
You'll learn:
Why every 3 letter .com was gone before the year 2000
How many 3 letter combinations actually exist
Which extensions still have unregistered 3 letter names
What a 3 letter .com sells for on the aftermarket today
Why domain registries charge premium prices for short names
Four realistic ways to get hold of a short domain

The short answer on 3 letter domain availability
There is no unregistered 3 letter .com left. Every combination was claimed during the first land rush of the 1990s, and by April 2000 the press was already reporting that the last 3 letter .com had gone. Since then the only route to one has been buying it from the current owner.
That does not put short domains out of reach. .com is one extension out of well over a thousand, and the newer ones have not been picked over anywhere near as thoroughly. Some still have 3 letter names available at the same price as any other domain.
The catch is which combinations survived. The obvious ones went first, so what remains tends to cluster around the letters nobody was fighting over.

How many 3 letter domains are there?
The maths is small, which is exactly why supply ran out so fast. A 3 character domain label can use letters, digits and hyphens, and the total depends on which of those you count.
3 letter domains with letters only
There are 26 letters in the English alphabet and 3 positions in the domain label:
26 × 26 × 26 = 17,576
So there are 17,576 possible 3 letter combinations using letters only. This includes combinations such as abc.com, xyz.com and qwe.com, without considering whether they form words or have a particular meaning.
For .com, this pool is effectively exhausted. All 17,576 possible letter-only combinations have been registered, so you won't find an unregistered 3 letter .com by simply trying different combinations.
How many 3 letter domains use letters and numbers?
If numbers are allowed, the pool gets larger. There are 26 letters plus 10 digits, giving you 36 possible characters for each position:
36 × 36 × 36 = 46,656
That means there are 46,656 possible 3 character combinations using letters and numbers.
Hyphens add another 1,296 theoretical combinations:
37 × 37 × 37 = 50,653
But not all of these are valid domain labels because a hyphen cannot appear at the beginning or end. Removing those invalid combinations leaves 47,952 valid 3 character labels when letters, numbers and hyphens are allowed.
These calculations describe the size of the possible pool. They don't mean that every combination can be registered on every domain extension. Registry rules, reserved names and existing registrations can affect what's actually available.
What counts as a 3 letter domain name?
The term 3 letter domain normally refers to the domain label, not the full domain including the extension. So abc.com is a 3 letter domain because abc contains 3 letters.
A different use of the term is a domain that's only 3 characters long from start to finish. For example, a.co has a 1 character label and a 2 character extension. That's a 3 character domain, not a 3 letter domain.
The distinction matters when searching for short domain names. If you're looking specifically for 3 letter domains, focus on the characters before the dot and treat the domain extension separately.
Which extensions still have 3 letter domains available
Availability swings wildly from one set of domain extensions to the next. Here is where things actually stand.
01. .ai and .io
These two are the best hunting ground right now. A domain investor inventory published on 30 November 2025 counted 1,006 unregistered 3 letter .ai names and 206 unregistered 3 letter .io names, roughly 5.7% and 1.2% of the full 17,576. Almost all of them lean on q, x, z, j, v and w, so think along the lines of qjz rather than abc. Standard registration pricing applies to both.
02. Legacy extensions like .net, .org and .co
Treat these as gone. They followed .com closely enough that the 3 letter space filled years ago, and anything that does lapse gets caught by a backorder service within minutes. A 3 letter name on .net, .org or .co means buying from an owner rather than registering it yourself.
03. Newer extensions
Extensions like .xyz, .app, .shop and .online still hold unregistered 3 letter strings, but the registries know exactly what they have. Short names on these are usually pulled into a premium tier with a price set by the registry rather than the registrar, and that premium often applies to the renewal as well as the first year.
04. Country code domains
The country code domains are the wild card. Some have plenty of 3 letter names left and price them normally. Others reserve short names entirely or release them through special programmes. The rules change registry by registry, which is exactly where a search that spans hundreds of extensions at once saves you a lot of guesswork.

What a 3 letter .com actually costs
All 17,576 possible letter-only 3 character .com combinations are registered, so buying one means going through the aftermarket rather than registering an unused name at standard pricing. The price depends on the specific domain, its letter combination, brandability and what the owner is willing to accept.
3 letter .com domain prices
A 2026 analysis of 3 letter .com prices identified 31 reported 3 letter .com sales between 2022 and 2026. Prices ranged from $75,500 to $1 million, with the largest number of sales falling between $200,000 and $400,000. The dataset is based on reported sales, so it doesn't represent every transaction in the market.
Recent sales show the range clearly. HSM.com sold for $550,000 in 2025 and UIG.com for $280,000. In 2026, TXT.com sold for $502,250 and TII.com for $170,000. DNJournal's sales data tracks these and other reported domain sales.
You'll sometimes see much lower prices quoted for 3 letter .com domains, but it's important to distinguish asking prices from completed sales. There isn't a fixed market price for an LLL.com domain, and private transactions may never be publicly reported.
How much do 3 letter domains cost on other extensions?
3 letter domains on extensions such as .ai and .io are a different market. If a combination is still unregistered, you can generally register it at the extension's standard price. Desirable names that are already owned can still command much higher aftermarket prices.
Expert tip from Milosz Krasinski, International SEO consultant and owner of Chilli Fruit Web Consulting:
“When I size up a domain, I don't just skim DR or traffic. I dig deep, who owned it, who linked to it and did Google ever slap it down? A domain isn't just a URL. If it's got the right domain history and weight, it's a business asset, and those don't come cheap.”
Why registries price short domains as premium
The legacy extensions run on a flat wholesale price. .com, .net and .org cost the registrar the same amount no matter how long or short the name is, which is precisely why a 3 letter .com can only come from its owner rather than from a price list.
Newer extensions and many country codes do the opposite. Registries set aside one, two and 3 character names in a reserved or premium tier and price them individually, sometimes into the thousands. That premium usually carries over to renewals, so a short name on a newer extension can be a recurring cost rather than a one off.
Check this before you fall for a name. The registration price you see at checkout is the registry's number, not a registrar markup.

How to get a 3 letter domain
There are 4 main ways to get a 3 letter domain, from registering an available name to buying one from its current owner. Your options and budget will depend largely on the extension and whether the name is already registered.
01. Search less saturated extensions first
Start with extensions where 3 letter names are still available. Search across multiple extensions at once instead of checking .com and stopping there. You may find the same combination available on a newer or less saturated extension at standard registration pricing.
02. Watch expiring domains and use a backorder
Registered domains can become available again when their owners don't renew them, although the process varies by extension. A domain backorder service lets you request a specific domain before it drops. Competition for desirable 3 letter names can be intense, so there's no guarantee you'll get it.
03. Find the owner and make an offer
If your preferred name is already registered, you can try contacting its owner directly. Some 3 letter domains are parked or unused and may be available for the right offer. A Whois lookup can sometimes provide information about the registration and available contact route.
04. Buy a 3 letter domain on the aftermarket
Domain marketplaces list names that their owners are actively selling. Prices can range from hundreds to hundreds of thousands of dollars, with .com names generally commanding the highest prices. Set your budget before negotiating and compare the asking price with recent sales of similar domains.
What to do if a 3 letter domain is out of reach
3 letters is not the only route to a name that sticks. 4 and 5 letter names built on alternating consonants and vowels read like real words even when they are invented, and far more of them are still available. Made up brandable names give you the same clean feel without the auction.
Adding a keyword or a location works too, and it does something a 3 letter acronym cannot. It tells someone what you do before they click. A short abstract name asks people to learn what it means, which is fine with a marketing budget behind it and expensive without one.
Expert tip from Keren Nir, Senior SEO Strategist at Wix:
“Shorter domains can be easier to remember and type, but they aren't essential. What matters most is that your domain accurately represents your brand and is memorable.”
If your first pick is taken, a domain name generator will turn your business idea into a list of available names in seconds. Usually faster than staring at a search box trying to invent something.

How to find and register your domain with Wix
Wix is an ICANN accredited domain registrar, so you can search, buy and manage a domain in the same place you build your website. Search runs in real time across more than 400 extensions, which matters when the whole job is working out which version of your 3 letters is actually free.
01. Search your name across every extension
Open the domain search and type the 3 letters you want. You get availability across .com, .net, .ai, .io and hundreds of country specific extensions in one go rather than one at a time.
02. Get alternatives when your first pick is taken
If the exact name is gone, the AI powered domain name generator takes your business idea and returns a list of available brandable options. That is where most 3 letter searches end up, and it beats guessing.
03. Check what the extension costs
Prices vary by extension, registration period and privacy options. The domain pricing page shows what each one costs before you commit, which is useful since short names on newer extensions often sit in a premium tier. Premium domains can be bought through Wix as well, so a short name listed as premium rather than unavailable may still be within reach.
04. Register it with privacy and security switched on
Choose your registration period, enter your contact details and select private registration with DNSSEC. That keeps your personal details out of public Whois records and adds protection against DNS attacks. Wix domains support names up to 60 characters, so 3 letters sits comfortably inside the limit.
05. Add business email and hosting
Once the domain is yours you can add a custom business email address ending in your own domain, and secure hosting is included when you build a website with Wix. Domain, website, hosting and email all live in one account with 24/7 support behind them.
When you upgrade to a premium plan, you'll even get a voucher for a free domain name for your first year.
3 letter domains FAQ:
Are there any 4 letter .com domains left?
No. Research published in December 2013 confirmed that all 456,976 4 letter .com combinations built from the 26 letters of the alphabet had been registered, so 4 letter .com ran out roughly 13 years after 3 letter did. The difference is liquidity. There are 26 times more 4 letter names in circulation, so they change hands in the low thousands rather than six figures, which makes 4 letters the realistic step down when a 3 letter name is out of budget.
What is the shortest domain name available?
1 character, though almost never on a legacy extension. IANA reserved every single letter and single digit second level name in .com, .net and .org on 1 December 1993 to keep them free for future use. Only six registrations predated that freeze and were allowed to stand, which is why q.com, x.com and z.com exist and no other single letter .com ever will. Single character names do turn up on some country codes and newer extensions, almost always in a registry premium tier.
Can I get a 3 letter domain for free?
No. Free domain offers apply to standard length names that nobody has registered yet, and no 3 letter combination on a mainstream extension fits that description. The closest thing is a 3 letter name on .ai or .io where the combination has never been claimed, which costs normal registration pricing rather than nothing. If a free first year is what you are after, that comes with a Wix premium plan voucher and applies to a normal length domain.
Is a 3 letter domain worth less if it contains a number?
Usually much less. Domain investors treat LLL.com, meaning 3 letters and nothing else, as its own asset class, and swapping any letter for a digit takes the name out of that class. Clean letter combinations resell more reliably because they read as acronyms and survive being said out loud, while mixed letter and digit names are harder to dictate and are more often bulk registered by speculators. The trade off is availability. Allowing digits widens the pool enormously, so something like fx8 can still be gettable when the letters only version is long gone.
How do I check what a short domain will cost to renew?
Look at the renewal price rather than the first year price before you commit. Registries place short names in a premium tier and that premium normally applies every year, so a name that looks affordable at checkout can renew at many times the advertised figure. Check the extension on a domain pricing page and confirm the renewal number specifically, since promotional first year rates are common. Registering for several years up front locks in the current price for longer.
How do I sell a 3 letter domain I already own?
Start with a valuation, because the gap between a weak and a strong combination runs into hundreds of thousands. Base it on reported sales of comparable patterns on the same extension rather than an automated appraisal tool. From there you have three routes. List it on an aftermarket marketplace for passive exposure. Hire a broker who works on commission and approaches buyers directly. Or contact companies whose initials match your letters and open the conversation yourself. Brokers earn their fee mainly on six figure names where finding one well matched buyer moves the price.
