The EU's General Data Protection Regulation (GDPR) is created to give people in the EU greater protection over their personal data. However, companies such as asset managers that hold vast amounts of consumer data are at risk.
This is in part because a United States law - the Children's Online Privacy Protection Rule (Coppa) - bans online services from collecting personal information about younger children.
If you live in any other country except those in the European Region, you must be at least 13 years old to use WhatsApp.
The Facebook-owned service will ask users to confirm their age when prompting them to agree to new terms of service on the platform in the coming weeks.
However, it plans to continue with its age limit of 13 in the rest of the world.
Whether other social media companies will follow WhatsApp's example is unclear, though Facebook has confirmed anyone between the ages of 13 and 15 will need to nominate a parent or guardian to consent to data collection.

2 more Democratic senators say they'll vote for Pompeo
Tom Cotton , R-Ark., who has been among Pompeo's most vocal champions in the Senate, lambasted his colleagues ahead of voting. He chalked up Democratic opposition to partisan election year politics, and not a statement on Pompeo's qualifications.
However, it remains unclear how WhatsApp will confirm this and enforce the new limit, as it does not now verify identity beyond its requirement for a working mobile phone number.
Facebook too is in the process of tightening its privacy rules post the data breach scandal. The EU data regulators are chiefly concerned over WhatsApp's sharing of user data with parent company Facebook.
GDPR is the biggest overhaul of online privacy since the birth of the internet, giving Europeans the right to know what data is stored on them and the right to have it deleted. As a Facebook product, WhatsApp, along with Facebook and Oculus have all been updating their terms of service to reflect the EUs GDPR.
WhatsApp reiterated that it is "not now sharing account information to improve your product and ads experience on Facebook".
The Facebook app has also setup an entity within the European Union to focus on implementing these different terms and "to meet the new high standards of transparency" that WhatsApp claims it will provide for its European Union users.
