What can be Registered as a Domain Under the .AR TLD?

Domain registration under the .ar TLD, managed by Argentina's national domain registry (NIC Argentina), follows a set of specific rules and guidelines to ensure appropriate usage and prevent misuse. The significant points to note are:

  1. Special Characters: Domains can include special characters, expanding the range of possible domain names. This includes the letters ñ, ç, á, é, í, ó, ú, ä, ë, ï, ö, and ü. This allowance helps support domain names in local languages and scripts, providing greater accessibility and relevance.

  2. Domain Length: Domain names can consist of between 1 and 50 characters. However, for domain names that are only 1 to 3 characters long, additional restrictions might apply. This restriction aims to prevent misuse and ensures a wide distribution of potential short domain names.

  3. Appropriate Content: Argentina will evaluate the viability of user requests through the intervention of the domain registration area of the NATIONAL DIRECTION OF THE INTERNET DOMAIN REGISTRY. This is to avoid the registration of domain names that are offensive, discriminatory, contrary to the law, or that could lead to confusion, deception, or identity theft.

These are the fundamental rules for registering a .ar domain name. For more information about these rules and to understand the complete regulations, you can visit the official NIC Argentina website here.
