The length of a domain name determines its quality. Generally, good domain names are relatively short. Many people may be unaware of the shortest and longest domain names.

The shortest domain names are single-letter domains, consisting of a single letter and a single number, such as a.com and 1.com. Single-letter domains are concise, memorable, and unique, making them highly sought after by domain collectors and investors. They are considered unique and extremely valuable.

Single-letter domains: A single English letter (a-z) followed by a suffix.

Single-number domains: A single Arabic numeral (0-9) followed by a suffix.

The shortest domain name is one letter, while the longest is 63 characters, regardless of the suffix.

Although single-letter domains are very valuable, they are rarely seen in the market. Currently, there are five main ones in circulation: Q.com, X.com, Z.com, Q.net, and I.net. Z.com is reportedly the only single-letter .com domain currently fully developed and used for website creation. It is used by a web service provider called GMO Internet.

It is understood that IANA once opened registration for top-level single-digit .com domain names, but quickly closed them. Only a few single-letter .com domain names have been registered, and no top-level single-digit .com domain names have been registered. In contrast, single-digit .cn domain names and single-digit .com.cn domain names are currently fully registered.
