My location was showing verified but it changed to not verified when I added an emergency number to use it on a site. What happened?
This situation indicates that the address in question is verified for postal services, but not for emergency services. When you add the emergency number to make the location available for use on sites, additional verification for emergency services is performed.
Emergency verification confirms that the exact geographical location of the address is known to emergency responders, so that responders can locate the caller if an emergency occurs. Emergency verification is provided directly by the carrier who delivers the call to the emergency responders. The nature and process of that verification varies by jurisdiction.
