From WHO How Long Corona Virus Lives On Surfaces Info For My Friends
They aren't exactly sure of all the factors, but the virus lives on surfaces from hours to days depending on environment. This is from WHO.
Just for information. This is the question I wanted answered the most.
"It is not certain how long the virus that causes COVID-19 survives on surfaces, but it seems to behave like other coronaviruses. Studies suggest that coronaviruses (including preliminary information on the COVID-19 virus) may persist on surfaces for a few hours or up to several days. This may vary under different conditions (e.g. type of surface, temperature or humidity of the environment).
If you think a surface may be infected, clean it with simple disinfectant to kill the virus and protect yourself and others. Clean your hands with an alcohol-based hand rub or wash them with soap and water. Avoid touching your eyes, mouth, or nose."
