We are out of 4-letter .com domains

4 letter domains

We used our domain API to check all the 4-letter combinations .com domains. For example

up to….

What we confirmed that all the 4-letter domains are registered. We haven’t tried numbers, dashes, or IDNs, just 26 letters of the English alphabet. This takes us to 456,976 combinations, or domains. Not to mention that 3-letter and 2-letter domains are long gone.

4-letter domains are also known in the domaining industry under the jargon LLLL.COM or 4L. . So for example, 1PRO.COM wouldn’t be a LLLL.COM domain. Also LLLL.COM doesn’t mean literal domain but a representation of a group of domains. Here’s a rough estimate how you should value 4-letter domains.

If all this is too much for you, and you are just looking for a nice pronounceable and brandable 5-letter .com domain, you can head over to Polar Vectors, they also include a spectacular logo!

Read Goran Duskic's answer to Have all 5-character .com domain names been taken? on Quora

L = letter
C = Consonant
V = Vowel

5. CVVV, CCVV, CCCV, VCCC, VVCC, VVVC… (these are more often named LLLLs)

What are popular 4 letter domains? (CVCV), (CVCC), (CCCC or LLLL), (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 4-letter generic words—cars, boat, card, etc.

It goes so far that 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 4-letter domain, that is memorable and easily pronounceable, 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.

  1. How did you come up with that ridiculous ranking when you list CVCC as one of the most lucrative value formats but it’s not even listed (implying it’s in the LLLL category) ? Park, Tart, Fart, Cart, etc…

  2. Google has consistently reported that dashes “-” do nothing to diminish page rank. Not sure why, but people still seem very reluctant to get on the dash bandwagon, it really opens up a lot of url possibilities. In any case, users should never be keying in your url directly, so the best strategy is just to hammer on your core keywords, use a dash if you need, and build traffic with direct links.

    • “In any case, users should never be keying in your url directly” That is just plain stupid. TV ads? On-street ads? Other people telling about your business?

  3. People aren’t falling for this shit anymore. You can get any name now to bring your website online. Alternative is or

    The domain name game is well and truly over guys. You’re all sitting on dead ducks. It’s finished.

  4. Historically, when paradigm shifts begin, those who are negatively impacted by it say it will never work and often work hard to stop or slow the shift. Currently, registries of legacy TLDs (think .com and .net) are attempting to slow the paradigm shift of the new gTLDs. But these shifts are inevitable and early adaptors and communicators who know this will be taking advantage of the first mover advantage and acquire the most premium of the new spaces as they come available. The new gtlds not only fill a need for memorable domain names, they are inspiring entrepreneurs to establish new businesses. sponsors, a site that publishes lists of new domains registered today for all TLDs.

  5. Would the value of but that much less than ? It seems very brandable. (Assuming they could acquire as well , as a redirect). What are your thoughts on #LLL or even ##LL and similar domains?

    • I guess a very good 4 letter domain with 1 number could be better than 4 letter domain with bad letters. It’s a different ball game if you have combined with It’s hard for me to imagine a top brand buying ##LL just to be there. I’d love to see a good case study. I can’t imagine Twitter going from to… Just my opinion.

    • What about it? Is it for sale, what is the price?

      There is definitely raising interest in good 5 letter .com domain, and many good ones can be found at base price!

  6. what is the difference in valuations? I have two 4 letter domains, and – earlier today I was offered $250 for the humh domain and I looked it up and some calculator valued it at $21K, really! Hell Yes! What do you think is the true value of a halfway decent 4 letter domain in reality.

    • Hi Suzanne

      I’d like to stay away from the evaluation debate. No matter what amount I say, you can easily get as many people to oppose me.
      I think we can all agree on something that’s currently established in the market, doesn’t have any numbers, and does. Also, HUMH are better letters compared to QWXY. Is worth $21k, it is if someone is willing to pay for it.

      You also have to take time into your equation. It might not sell this year, but would you be willing to hold it for 5 or 10 years if someone promised you to buy it for $21k then?

    • Well, first of all, 6size has a number in it, and numbers weren’t included in this research. Do you happen to know if there are any 4 letter domain names, that include numbers available for base registration?
