In an increasingly connected world, country codes play a crucial role in communicationand global identification. Whether you’re dialing an international number, shipping goods across borders, or analyzing global data, understanding country codes is essential. These codes come in various formats, including telephone codes, ISO 3166 codes, and internet country domains.
This article provides a detailed overview of the key types of country codes, along with a comprehensive country code list to guide you through their usage.
Types of Country Codes
1. Telephone Country Codes (International Dialing Codes)
Telephone country codes are used for international calls. These numeric codes are preceded by a “+” symbol and help direct calls to specific countries or regions. For example, the United States uses +1, while India uses +91.
2. ISO 3166 Codes
The ISO 3166 standard assigns a two-letter (alpha-2) and a three-letter (alpha-3) code to each country for official and administrative purposes.
- Alpha-2 codes: Widely used in internet domain names (e.g., “.us” for the United States, “.uk” for the United Kingdom).
- Alpha-3 codes: Common in trade and international data systems. For example, the United States is USA, and Germany is DEU.
3. Numeric Country Codes
These are three-digit codes used by organizations like the United Nations for statistical purposes.
4. Internet Country Codes
Every country is assigned a top-level domain (TLD) used in website addresses. For instance, .fr represents France, while .cn represents China.
