Characters  to Use on Your Domain

If you are new to choosing a domain name you will want to know more about the characters that can be used within this name. Throughout this article we will describe some of the features related to these characters to know more about registering for the first time with a name. When it comes to second level domain names, then the length can be up to 63 characters.

These are names with a label that precedes the registry extension (the Top Level Domain – TLD) directly. Following is a guide for those characters that are considered valid within the use of domain names, even if here and there you can meet some exceptions to the rules. They will be as well displayed for your knowledge down below.

  • Alphabet’s letters are allowed.
  • Any of the numbers from 0 to 9.
  • Hyphen can be used as long as domain name doesn’t start and/or en with it.
  • Combinations of letters, numbers and hyphens are also allowed.
  • You can use numbers to begin and/or end a domain name.
  • It is possible to use multiple instances of hyphens, but there are cases where you can not use double hyphen.
  • You can not use forms of punctuation, accent characters or symbols.
  • As to the length of the domain name, this one can range between 3 and 63 characters.
  • All of the above can be resumed in the ‘LDH’ rule meaning ‘Letter, Digits, Hyphens’.
  • When it comes to double hyphens, they can be used for generic extensions such as .net, .com, and .org. However, with some country code TLD operators, they are not allowed, for instance as it is the case with extensions of Australian origin. More than this, you should know that many people see the use of double hyphens as an indication of ‘spammy domains’.

Accent characters have in their turn some exception to the rules in that they can be used in relation to some domain names that are known as Internationalized Domain Names – IDN. One example in this direction is the ‘eu’ extension. These IDNs will allow non-ascii characters of the type used in Chinese, Korean and Japanese scripts and Greek alphabet.

If you wonder about the use of capitalization, you don’t need to worry too much about this: both of lower case and upper case are allowed and even combination of these two is allowed.

As mentioned above the length of the domain name can go up to 63 characters, but think about it: would you want to use such a long name? It is in your own interest for the domain name to be shorter as in this way it is easier to be remembered by users. More than this, try to keep the name simpler and correctly typed because the way you choose it now it will be remembered and used for the future.
