The new feature - which was launched this week by the Poynter Institute for Media Studies' International Fact-Checking Network (IFCN) - will connect the messaging app's users with more than 80 organisations to tell them whether certain informaton is false.
The database includes rumours determined as false - including fake vaccines and miracle cures - as well as racist misinformation about the spread of the coronavirus, and false claims that COVID-19 was caused by 5G.
IFCN's director Baybars Orsek said: "Hundreds of millions of users rely on WhatsApp to stay in touch with their friends and families every day.
"Since bad actors use every single platform to disseminate falsehoods, to mislead others during such troubling times, fact checkers' work is more important than ever."
Furthermore, the Facebook-owned messaging platform has also created a coronavirus information hub, limtied message forwarding and donated $1 million to help fight fake news.
