### Answer
Based on the available sources, there doesn't appear to be an officially published list of sanctioned countries in Retell's documentation. [(1) ](

However, from Discord support responses, the following countries have been identified as sanctioned regions where calls are not allowed: Cuba, Iran, North Korea, Syria, Russia, Belarus, and Venezuela.
The Terms of Service reference export control compliance, stating that customers must not be located in a country subject to U.S. Government sanctions and must not use the Services in violation of U.S. export control laws. [(2) ](

For an official, up-to-date list, I'd recommend reaching out to Retell support directly at compliance@retellai.com.
