Google Voice is a calling and messaging service that lets users make and receive calls at voice.google.com or on the Google Voice app. It provides free domestic and international calls, call forwarding, and voicemail services.

Google Voice numbers allow users to make and receive calls from web browsers and mobile devices. When calling from the US, almost all Google Voice calls to the US and Canada are free. Users can call directly from voice.google.com by searching for contacts or entering phone numbers. Call forwarding can be set up to link phones so calls to a Google Voice number ring linked phones. The service includes voicemail transcript reading in inboxes, searchable like emails, and uses Google AI to block spam calls and transcribe voicemails to text automatically.
