Address Showing up in wrong state!!!!

This is a real estate website with over 300k records in the database so i can't just use city state zip. People searching for homes need exact addresses. The only time i want it to default to city and zip is when the street address can't be found.

Is there a way to change the default so that it will located the city, state, zip? When i type the address into google it doesn't locate an address but when i type in just the city state zip (DINOSAUR, CO 81610) it does locate that location.

I can't have all these random pins showing up in texas or my map to be tiny trying to squeeze in these texas pins? Is there a way to make the default city, state, zip or make it so that when the address isn't located that it doesn't show up at all?

Thanks.
