A Country Calling Code is a numerical prefix used for dialing international telephone calls. Each country or region has its own unique code, allocated and managed by the International Telecommunication Union (ITU) to ensure orderly global communication.
Most Asian country codes start with 8 or 9, such as China (86), Japan (81), India (91), South Korea (82). Southeast Asian countries like Thailand (66), Vietnam (84), etc.
European country codes start with 3 and 4, such as the UK (44), France (33), Germany (49), Italy (39), Russia (7). Nordic countries like Sweden (46), Norway (47).
African country codes start with 2, such as Egypt (20), South Africa (27), Nigeria (234), Kenya (254), Morocco (212), etc.
North America shares the code 1, e.g., USA (1), Canada (1). Central and South America include Brazil (55), Mexico (52), Argentina (54), etc.
Oceanian country codes start with 6, such as Australia (61), New Zealand (64), Fiji (679), Papua New Guinea (675), etc.
There is no single area code +85. There is area code +852, which is the international code for Hong Kong; and area code +855, which is the international code for Cambodia.
Enter a country name, Chinese name, or international area code in the search box, and the system will filter matching results in real-time. Supports fuzzy search, e.g., entering "美" can find the United States, American Samoa, etc.
Use the continent filter to quickly view countries in a specific region. Supports filtering by Asia, Europe, Africa, Americas, and Oceania, helping you narrow down your search scope.
Sort results by country name, or by area code in ascending or descending order, making it easy to compare area code patterns across countries or quickly locate countries within a specific area code range.
Each country is preceded by a flag icon, helping you quickly identify the country. Both English and Chinese country names are displayed for convenience across languages.
Provides primary timezone information for each country, including UTC offset and timezone name, helping you understand the current time in the target country for choosing appropriate calling times.
Displays each country's Internet top-level domain (TLD), such as .cn (China), .us (United States), .jp (Japan), etc., making it easier to identify a website's origin or register international domain names.
International number format: International Access Code + Country Code + Local Number. For example, calling a US number from China: 00 + 1 + area code + phone number.
The International Access Code is the prefix used to dial an international call, varying by country: China (00), USA (011), Russia (810), Japan (010), etc.
To call an international mobile: International Access Code + Country Code + Mobile Number (usually omitting domestic area codes). Note that some countries have special prefixes for mobile numbers.
To call an international landline: International Access Code + Country Code + City Area Code (omit the domestic trunk prefix 0) + Local Number. For example, calling a landline in London: 00 44 20 xxxx xxxx.
International call charges vary depending on the operator, destination, and calling plan. Using VoIP (Voice over Internet Protocol) or international calling cards is recommended to reduce costs.
Be mindful of time differences to avoid late-night disturbances. Confirm the correct number format. Check if international calling is activated on your line. Be aware of the validity period and balance when using international calling cards.
Large countries like the United States, Canada, and Russia require multiple area codes due to their vast geographical size. The US has over 300 area codes covering 50 states and overseas territories.
International area codes are generally stable long-term, but changes can occur under special circumstances such as country division (e.g., the dissolution of the Soviet Union), country unification (e.g., the unification of Yemen), or telecommunications restructuring. Advance notice is usually given before any change.
Special regions like Antarctica (672) and the International Space Station (870) have dedicated codes. Calling satellite phones typically uses specific prefixes, such as Inmarsat (870-874).
Both international area codes and country code top-level domains (ccTLDs) serve as national identifiers, but they are assigned by different organizations. Area codes are allocated by the ITU, while domain codes are managed by IANA. There is no direct correspondence between them.
The North American Numbering Plan (NANP) covers 20 countries including the United States, Canada, and parts of the Caribbean, sharing area code 1. This is a historically established unified telephone numbering system.
There is no country code starting with +0. When dialing internationally, some countries require adding a 0 before the domestic area code, but the international country code itself does not begin with a 0 prefix.
