In Middlesbrough almost 7,000 tests have identified 27 positive cases since the Council's programme was launched in February.
It is open to anyone who lives or works in Middlesbrough, but is particularly aimed at those who can't work from home and come into contact with lots of people.
All adults in England are now being encouraged to take lateral flow tests twice a week to support the roadmap out of lockdown.
South Tees Joint Director of Public Health Mark Adams said: "Every rapid test someone takes helps us get back to normality sooner and safer. The more people that get into the routine, the better chance we have of staying on top of Covid.
"By identifying positive cases that would have otherwise gone undetected, leading to further infection, we're able to prevent outbreaks, help businesses to stay open and ultimately save jobs.
"Regular testing is fast, free and easy to do. Alongside the vaccination programme and people following social distancing rules, it's so important for the immediate future."
If people test positive and self-isolate along with their contacts, it can help stop the virus spreading.
Anyone who gets a negative result after a rapid test must continue to follow all social distancing rules.
Free rapid tests can be ordered online via www.gov.uk/order-coronavirus-rapid-lateral-flow-tests or by calling 119.
