Soon, Europe's GDPR privacy standards will launch. Several companies have already announced changes that will affect European users, and you can add WhatsApp to that list. Sky News reports that WhatsApp changes it age requirements to comply with the new regulations by the GDPR standards. Users living in Europe will have to be at least 16 years old before they can use the service.
In the coming weeks, WhatsApp will be asking its users to accept the new terms of service. At that point, European users will have to confirm that they are at least 16 years of age before allowed to user the service. Users that are not living in Europe will still be held by the current standards requiring users to be no younger than 13 years old.
The issue that WhatsApp will run into is how it will verify users' age. The service hasn't provided any details on how it will go about verifying users ages.
