Four letter domain names are quite simply domains containing only four characters with each of these characters being a letter. Very recently, all four letter domain names in the popular dot com extension have been registered. This leads to some interesting observations and opportunities.
Not too long ago, a small pool of four letter dot com domain names were available for registration. The number steadily declined over the past two years as individuals and companies began to realize their unique value. On November 22, 2007, the scales tipped and the last of the available names in the pool were registered. Now whenever one expires it is immediately captured through a drop catching service or registered by a new holder.
Four letter domains have many benefits. Primarily, they are short and easy to remember while remaining economical for most individuals and businesses. Any shorter and the name would be much more difficult to acquire. Any longer and the name would start to lose some of its cache. A short, memorable identity provides a powerful tool for marketing and brand building. Look at some recently created brands which fit into this category: xBox, iPod, Digg, Hulu.
Four letter domains are relatively scarce. There are only 456,976 possible combinations. While this might seem like a large number, compare this to the total registered dot com names of over 55 million. As increasing number of individuals begin to see the unique value of these names, there may not be enough to go around.
In the wide world of domain names and the internet, four letter domains are certainly an area that bears watching.
