The new website https://www.covidtests.gov/ appears to be up and running.
This site offers COVID-19 information as well as the opportunity to order 4 free tests shipped to your residential address. Tests are expected to ship within seven to 12 days of being ordered. Initially, there will be a limit of four tests per residential household.
The White House will also set up a hotline for those who cannot order online but has not yet announced a launch date for it.
