Yes. Genesys Cloud Voice supports the Enhanced 911 service (E911). E911 services are automatically included as part of the Genesys Telecom US and Canada VoIP services.

While the E911 services provide a means of emergency dialing, you need to be aware that because E911 services are Internet-based, and as such are different than traditional 911/E911 services. 
 
More specifically, E911 service may be limited or unavailable under certain circumstances including, but not limited to: a power outage or broadband (Internet) service disruption (regardless of cause), use of a non-native telephone number, failure to successfully provide a valid, current address, or delays or interruption in the transmission of your geographic location. As a backup, you should strongly consider obtaining a PSTN connection from the local exchange carrier or similar provider.
