Google also uses this method. Beyond Google, your local 911 center uses it to dispatch first responders to your location. So beyond pizza you should be more concerned if an ambulance or firetruck can find you. Just telling Google will only help if they are using Google. You may want to check with your county emergency services.
There is an association called National Emergency Numbering Assoc (NENA.org) that sets standards for addressing. So when you call 911 services can find you.
