Starting on Monday, September 25, 2023, you can visit COVIDTests.gov to request a package of four free tests to be sent to your home. Here are some key points:

    Eligibility: You can request one four-test package per household, even if you've received free tests from the program before.

    Delivery Time: It's not specified how long it will take for the government to pack and send the tests, but they will arrive quickly via first-class mail for most of the U.S. and Priority Mail for Alaska, Hawaii, U.S. territories, and APO/FPO/DPO addresses. You'll get a shipment notification and tracking number if you provide an email address.

    Old Tests: If you have old tests, check their expiration dates. Some tests have had their expiration dates extended, and you can check the FDA's list to see if yours are still good to use.

    Effectiveness: The tests available through COVIDTests.gov can detect currently circulating variants. If you have old tests, you can check the FDA's list to see if they are still effective against new strains.
