Enhanced 911 (E911) service automatically delivers your location and callback number to local 911 emergency services personnel. You may already have E911 in your area, so in order to check just dial 933 from your Vonage phone. If E911 is unavailable in your specific area at this time, it could be offered soon. In the upcoming months we will be rolling out E911 to many more states and communities. If you are an existing customer, we will notify you when we are able to offer E911 in your area.
