Verify Geographic (Geo) Permissions allows you to control the Verification traffic to a destination country for SMS and Voice channels. Keeping permissions disabled for countries you don't use helps reduce the risk of bad actors exploiting your application by artificially inflating traffic through SMS pumping or toll fraud. See Preventing Fraud in Verify for more information.
You can access the Verify Geo Permissions page in your Twilio Console by navigating to Twilio Console > Verify > Settings > Geo permissions.
Permissions saved on this page will take immediate effect.
