To get your four free tests, you need to head to covidtests.gov. Once there, click on “Order Free At-Home Tests.” This will take you to a USPS website where you need to enter your information. They need your name and address. You can also share your email address if you’d like to be notified when the tests ship.

Once you order your four free tests, if you signed up with your email, you’ll get a confirmation that your order was placed.

The email also breaks down the fine print, clarifying that one set of four tests will ship to each address. “At-home COVID-19 tests will ship free starting in late January. USPS will only send one set of 4 free tests to valid residential addresses. We are unable to process duplicate orders for the same address,” the email reads.

That means if you have 11 people living in your home, you can still only place one order for that address. While that’s unfortunate, these measures were likely put in place to prevent scalpers from ordering excessive quantities and selling them.

If you want to make sure you get your test (currently, it says they’re shopping at the end of January), make sure to head to the website soon and get your order in, as there’s sure to be a backlog of people attempting to redeem their freebies.
