Zoom Phone supports international calling to destinations around the world, with availability and calling rates varying by country or region. International destinations are grouped into different calling tiers based on their associated rates and availability. Use the information below to determine which countries are supported and what calling tier applies before placing an international call. Some countries and destinations are considered Special Countries/Regions which require special authorization and cannot be enabled through the standard request process. Access to these destinations requires review and assistance from Zoom Support.
