Free COVID Tests from Government Available Again September 25, 2023 The U.S. government is once again offering free COVID-19 tests to every household. Each household can order four free rapid tests through the COVIDTests.gov website. The tests will be shipped directly to the household's home, and there is no limit on how many times a household can order tests. The Biden administration has partnered with USPS to deliver the free tests. The tests are expected to ship within 7-12 days of ordering. The government's free COVID test program is part of its ongoing effort to make testing accessible and affordable for everyone. The program was first launched in January 2022, and it has already provided millions of free tests to Americans. The government's free COVID test program is especially important during the fall and winter months, when COVID cases typically rise. Free testing can help people to identify and isolate themselves ea...
