Country Domain Extensions (ccTLDs) List

• Developers building country-selector dropdowns or domain validation tools
• DNS engineers and sysadmins referencing ccTLD codes for routing and records
• Researchers and analysts mapping web presence by country domain extension

Looking for a complete country domain extensions list to power a dropdown, validate a form field, or build a DNS reference tool? This page provides country-code top-level domains (ccTLDs) for all UN member states, the two UN observer states, and Taiwan, ordered alphabetically by country name and ready to copy in text, JSON, or HTML formats. Each entry pairs a human-readable label — such as 'Germany - .de' or 'Japan - .jp' — with a clean machine value containing just the ccTLD code including its leading dot. The text format is ideal for documentation and spreadsheets, the JSON format gives you a bare array of ccTLD strings perfect for validation logic or seed data, and the HTML format generates ready-to-paste select option tags for web forms. Most ccTLDs are two-letter codes assigned by IANA using ISO 3166-1 alpha-2 country codes as the basis for eligibility, making them a useful geographic signal for domain categorization, geolocation tooling, and internationalization work. Developers commonly use this list to seed country-domain dropdowns, power DNS lookup utilities, and filter web traffic by region. Because the leading dot is included in every value, you can concatenate ccTLDs directly without additional formatting.

• Use the JSON format when validating domains in code — values include the leading dot for direct string matching.
• Note that some ccTLDs (.tv, .io, .co) are widely used commercially outside their home country, which may affect geographic filtering logic.
• If your use case requires only IANA-delegated and actively operational ccTLDs, cross-reference against the IANA Root Zone Database before deploying.
