The United States Postal Service has begun taking requests for free at-home COVID-19 tests, which will ship “in late January.”

Every household is entitled to four tests free of charge. You can sign up here.

CBS News reports:

Public interest in the site is already surging, leaving all other government websites far behind, according to a website that tracks web traffic to government sites. By early Tuesday afternoon, almost 380,000 had visited the test website, while interest in tracking packages sent using the U.S. Postal service was just over 31,500.

“The White House also says it plans to launch a hotline that will allow Americans to order their own tests over the phone, if they have difficulty ordering on the website,” CBS News adds.

CNN provides additional context:

Given the formal launch wasn’t expected until Wednesday, a White House official said this is only the beta phase to ensure the site works seamlessly.

“In alignment with website launch best practices, is currently in its beta phase, which means that the website is operating at limited capacity ahead of its official launch,” a White House official told CNN. “This is standard practice to address troubleshooting and ensure as smooth of an official launch tomorrow as possible. We expect the website to officially launch mid-morning tomorrow.”

Last week, President Biden announced that his administration has ordered a billion at-home tests. Free high-quality masks will also be distributed by the federal government. Details are forthcoming.
