Americans who want to get free COVID-19 tests mailed to them by the federal government are once again able to request them as of Monday, after the White House restocked the program for the holiday travel season and an expected seasonal rise in coronavirus cases.

At covidtests.gov, each residential household can order four free rapid antigen COVID tests, which will begin shipping on November 27. Those who did not order tests during the last round in September are allowed to order a total of eight tests.
