International country calling codes are unique numeric prefixes assigned to every country and territory in the world, which you must dial before the national phone number when placing a call from abroad. The website PhoneNumberWizard.com offers a comprehensive reference listing for these international phone codes, making it easy to find the correct prefix for any country you need — whether for travel, business, or verifying number origins. This resource includes the country name, its corresponding dialing code (often with a “+” sign before the number), and related ISO codes. For example, countries like Afghanistan use +93, Australia uses +61, and Bangladesh uses +880 as their international dialing codes — all accessible in a well-organized list on the site. This global directory simplifies international communication by helping you quickly identify or confirm the right country code for any phone number you encounter.
