People in the U.S. can order up to eight additional COVID tests for free

Flashback: The at-home COVID test program, which first launched in January, initially allowed for four free tests per residential address, regardless of how many lived in a household. Then in March, another four kits could be requested.

What's happening: This time, households can order eight rapid antigen tests that will come in two separate packages of four kits, according to the U.S. Postal Service website.

• The tests are available at no cost and ship for free.
• The test kits can be ordered at COVID.gov, which then directs to the USPS website.
• For those who can't order through the website, there's also a hotline, 1-800-232-0233.

The big picture: "To promote broad access, the program allows 3 orders of free at-home tests (16 tests total) per residential address," an update to the frequently asked questions on Covid.gov states.
