Back in December 2013, we used our domain availability API to check all the combinations for four-letter .com domains. For example
All the four-letter com domains are registered
What we confirmed is that all four-letter domains are registered. We haven’t tried numbers, dashes, or IDNs, just 26 English alphabet letters. This takes us to 456,976 combinations or domains. Not to mention that three-letter and two-letter domains are long gone. So, if you want to switch gears and register other domain names, here’s a list of good domain registrars.
Four-letter domains are also known in the domaining industry under the jargon LLLL.COM or 4L. So, for example, 1PRO.COM wouldn’t be an LLLL.COM domain. Also, LLLL.COM doesn’t mean the literal domain llll.com but is a representation of a group of domains.
L = letter
C = Consonant
V = Vowel
5. CVVV, CCVV, CCCV, VCCC, VVCC, VVVC… (these are more often named LLLLs)
What are Chinese premium domains?
For a deeper explanation of consonant-vowel combinations or the Chinese premium domain, I would advise looking into this LLLL investment guide – click here.
What are the popular four-letter domains? Nike.com (CVCV), SONY.com (CVCC), HSBC.com (CCCC or LLLL), Ford.com (CVCC).
Especially popular (worth more) CVCV domains are where the same consonant and vowel are repeated. Bobo, Gogo, Zaza, Vivi, etc. They are short, memorable, and easily pronounceable. However, it goes without mentioning that the most expensive 4-letter domains are four-letter generic words: cars, boat, card, dogs, cats, etc.
It goes so far as there is a general consensus among domainers, and letter frequency statistics also indicate that there are premium letters, average letters, and bad letters.
•Premium letters: a b c d e f g h i l m n o p r s t
•Average letters: j k u v w
•Bad letters: q x y z
If you want a short four-letter domain that is memorable and easy to pronounce, you are probably going to have to shell out some serious cash in the aftermarket. Do you own any 4-letter domains? Let us know in the comments.
Four-letter .com domain names that are for sale
If all four-letter .com domain names are registered, does that mean there are no four-letter .com domain names that are available for purchase? Absolutely not! Your best bet to get a four-letter .com domain name is from a domain investor. These companies and individuals have purchased these four-letter .com domain names from other domain investors, or they registered them when nobody else would. Most of these domains are very old. This means that they never reached their expiration date. Somebody registered them a long time ago and paid renewal prices every year, sometimes for 20 years.
Here’s a list of four-letter .com domain names that are for sale. Next to them is a creation date (when the domain name was first registered), according to whois.
LVCB.COM Created On: 02/24/1996
QWLI.COM Created On: 10/05/2013
LAEQ.COM Created On: 10/14/2006
Are there any unregistered 4-letter domains?
There are still unregistered 4-letter domains, but not on .com TLD (domain extension). As you can already see by the image below, there are unregistered 4-letter .net domains. With that being said, I think we can make an educated guess and assume that there are unregistered 4-letter domains on every other TLD except .com. Are any of these domain names worth something? That’s hard to say. Domain investors would probably price them on the low end. We have to be careful and not compare apples to oranges. We can’t compare the value of LVCB on a .com TLD, and a premium domain name (4 letters on a not-com) such as cars .online.
So, yes, there are unregistered 4-letter domains, but if no one is buying them, you have to ask yourself two questions. Are they worth anything? How will I be able to resell these domains?
We still have four-letter .net domain names
Just because we are out of four-letter .com domain names, it doesn’t mean there are no four-letter .net domain names. As a matter a fact in October 12, 2021 we used our Domain Availability API again! This time we checked all four-letter .net domain names. It turns out there are a lot of them that are available for registration. Click here to learn more about our research on four-letter .net domains.
With that being said, once you take into account hundreds of TLDs (domain name extensions), surely there may be as many as 50 million available four-letter domain names that are available for registration.
We still have five-letter .com domain names
In case you were wondering if there are any five-letter .com domain names available for registration, yes, there are! We haven’t checked all 11.881.376 5-letter .com domain names, but after several manual whois checks, we found that there are plenty of available five-letter .com domain names. Here’s an article on how you could get your hands on a list of available 5-letter domains. It’s not going to be easy to get that list, and furthermore, it’s not going to be easy to work with that list. There are a lot more five-letter .com domain names than there are four-letter .com domain names.
Also, I suspect that there are millions of five-letter .com domain names that are available for registration. This means it will be hard to find some that are worth anything. More on that in the article I just mentioned.
