The tests are part of the Biden administration's purchase of 500 million tests last month to help tackle a record surge in infections.
While COVIDTests.gov was expected to start accepting orders on Wednesday, an "Order free at-home tests" button was added Tuesday, which brings users to Usps.com/covidtests to order four at-home free tests. USPS will only send one set of four free at-home COVID-19 tests to valid residential addresses.
Also, Americans with health insurance can get up to eight at-home COVID-19 tests for free.
Private health plans are required to cover the over-the-counter tests at up to $12 per test. Consumers can either get the testing kits at no cost at participating pharmacies that their plan sets up or submit receipts for reimbursement from the insurance company.
A family of five could be reimbursed for up to 40 tests per month under the plan. PCR tests and rapid tests ordered or administered by a health provider will continue to be fully covered by insurance with no limit.
