The FCC said its new text-to-911 requirements apply to wireless carriers and “interconnected” text messaging providers (i.e., those which enable consumers to send text messages to and from U.S. phone numbers). This includes providers of “over the top” applications that support texting to and from phone numbers but not, for example, messaging apps that only support communications among users of games or social media.
The FCC also adopted a Third Further Notice of Proposed Rulemaking that seeks comment on the continued evolution of text-to-911, including the delivery of location information and support for text-to-911 when roaming.
The FCC previously adopted rules requiring text messaging providers to send an automatic “bounce-back” text message to consumers who try to text 911 where the service is not available.
