The popular messaging company currently allows anyone above the age of 13 to use the app, but that's all set to change, with WhatsApp now intending to increase the limit to 16.
Presently, the company - which is owned by Facebook - doesn't ask its users to confirm their age, nor does it cross-reference the information with other popular platforms, such as Facebook and Instagram.
The announcement comes shortly after Google started to roll-out its new Chat messaging service.
The American tech giant's new feature boasts a number of impressive functions, allowing consumers to create group chats, make video calls and read receipts - and it is to be integrated on the default messages app on Android phones.
Although the feature has actually been in the works for a period of years, it is only now hitting the market,with Google hoping its latest launch emerges as a rival to Facebook Messenger and WhatsApp.
In contrast to Chat, Google has paused development of Allo, which launched in 2016, but has failed to make the impact the company had hoped.
