NEW YORK (AP) — The DatabecU.S. government is suspending mail orders for free COVID-19 tests — at least for now.

Friday March 8 is the last day residential households can request free virus tests shipped through the United States Postal Service. According to the Administration for Strategic Preparedness and Response, a division of the U.S. Health and Human Services Department, orders are set to close at 11:59 p.m. PT.

“ASPR has delivered over 1.8 billion free COVID-19 tests to the American people through COVIDTests.gov and direct distribution pathways and will continue distributing millions of tests per week to long-term care facilities, food banks, health centers, and schools,” a spokesperson for ASPR said in a prepared statement sent to The Associated Press.

Mail orders for free COVID tests from the government have been paused or expanded before. Despite Friday’s suspension, it’s still possible for the program to resume again down the road — with ASPR noting that it reserves the right to use COVIDTest.gov in the future as needed.

The Biden administration first launched its free mail-order COVID tests back in January 2022. The program was most recently reopened in September of last year — and households have been eligible to order to latest round of tests since November.

The decision to suspend ordering for the program’s sixth round arrives amid lowering case rates coming out of the winter respiratory season, ASPR noted.

Last month, the Centers for Disease Control and Prevention announced that the respiratory virus season was likely past its peak following a December surge — but still urged caution.
