Available 4 letter domain names

As you may know, back in December 2013 we did a large domain availability research and proved that all 4 letter .com domain names are taken (at least the ones consisting only of consonants and vowels of the English alphabet). Here’s a quote:

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

AAAA.COM
AAAB.COM
AAAC.COM
AAAD.COM
up to….
ZZZX.COM
ZZZY.COM
ZZZZ.COM

What we confirmed that all the 4 letter domains are registered. We haven’t tried numbers, dashes or IDN’s, just 26 letters of the English alphabet. This takes us to 456.976 combinations, or domains.

Does that mean there are no 4 letter domains? Absolutely not! After all, it’s been a few years that all those domains were taken, we just wanted to be sure nothing changed, and we wanted to test our API. There are millions of 4 letter domains on other TLD’s beside .com. Also, there are a lot of .com domains if you include numbers and dashes. But most importantly, there are places where you can buy 4 letter .com domains. Here are 4 places where you can find them.

1. Domain investor portfolio

Let’s face it, all the 4 letter domains are registered, and a lot of them were registered by domain investors. Find their portfolios, and approach them in order to buy a four letter .com domain.

2. Domain marketplace

You probably heard of domain marketplace. Sedo, Snapnames, Godaddy auctions, Flippa or any other domain marketplace. It’s kind of like eBay that specializes in domain sales on the aftermarket.

3. Domain forums

There are forums that specialize in domaining, and you will probably find good four letter domain names over there. Try DNForum, Namepros, and even Web Hosting Talk

4. Classifieds

I’ve seen domains advertised and sold on local classifieds, Craigslist and on eBay. So there’s a good chance you can find it there as well. Just be careful with classifieds since people post “premium four letter domains”, and they are not really premium. Some aren’t even .com, so definitely read between the lines.

In case you want to confirm by yourself that those domains are really registered, or that the trend has changed you can still use our tool and API for massive domain availability checks. These also come in handy if you want to check short domain names on other TLDs (other than .com) there are still some available. Or if you want to include numbers, also perhaps worth looking into.

P.S.
