CountryCode is a comprehensive directory designed to assist users in making international phone calls. Essentially, it serves as a searchable database where you can quickly find relevant information for every country, including country codes, ISO country codes, population, land area, and Gross Domestic Product (GDP). If you are planning a trip to a country you've never visited, this website also provides complete travel information.

CountryCode dedicates a specific page to each nation, displaying detailed information. Besides ISO country codes and telephone country codes, it also covers practical information useful for travelers. This includes ISO codes, dialing codes, as well as travel essentials such as currency, language, electrical outlet types (which can also be checked on CheckPlug), local time, time difference, and weather. The interface is in English but is easy to understand.
The website primarily focuses on the telephony aspect, so it also displays area codes (Dial Codes) for cities within each country. While this information is available on Wikipedia, CountryCode organizes it more clearly and makes it easier to look up.
