Choosing the right one depends on your business type, industry, and brand identity. The email domain, .int, is categorized into sTLD category, which has specialized domains that specific communities or organizations sponsor.

What are the Requirements to Register for the .int Domain?
To register in the .int domain, the applicant needs to be an inter-governmental entity that satisfies RFC 1591's requirements. For each organization, only one registration is permitted, and the registration is free of cost.
If you are looking to apply for a .int domain name, please take into account the following three factors. These requirements must be met before a .int domain name can be registered.
- International Treaty: There must be an international treaty between or among the governments. You must provide a genuine certified copy of the international treaty, or it should be available in the UN's online treaty database. Make sure the document you offer is a treaty rather than the organization's constitution or bylaws. Organizations with observer status at the UN General Assembly and UN specialized agencies are recognized as qualifying organizations for domain names under the .int top-level domain.
- Established by the Treaty itself: The organization requesting the an .int domain name must be established in the treaty that is submitted. The treaty itself must create the organization; a council decision or other comparable action is not permitted.
- Independent International Legal Personality: The organization must be subject to and governed by international law, and it must be generally accepted that it has independent international legal personality. A declaration or treaty must have established the organization. The organization must have a legal personality if it is a secretariat. It must, for example, be able to sign contracts and participate in legal proceedings.
Along with NATO, other organizations use .int domain name, like:
- The Asian-African Legal Consultative Organization (AALCO)
- The World Health Organization (WHO)
- The International Telecommunication Union (ITU)
- The World Intellectual Property Organization (WIPO)
- The World Meteorological Organization (WMO)
The common thing between all of them is that they are all intergovernmental organizations established by international treaties. For instance, NATO was established because of the North Atlantic Treaty (also known as the Washington Treaty), signed in 1949. The purpose was a political and military alliance for collective defense among member countries.
Similarly, the rest of the organizations were formed because of a treaty, and if your organization also fits the definition, then you are eligible to get a .int domain name.
