Permissions can be enabled in each country. Each country can have up to a dozen number types and hundreds to even thousands of number ranges unique to that country. Twilio has classified the number ranges that have the highest risk of telecom fraud.
Now you can quickly enable calling to only low-risk destinations in each country while blocking calls to high-risk destinations in a few clicks.
Warning
Note: Only Owner and Administrator roles can update Geographic Permissions.

Info
These number ranges consist of all number ranges Twilio has classified as low-risk. Only turn on calling to countries you need to call. Most mobile and landline/fixed number ranges fall into this category.
