TikTok has announced that it will be rolling out alerts for missing children to US users.
Alerts will be shown within the For You feed, and will include a photo of the child, details and contact information.
The platform has partnered with the National Center for Missing & Exploited Children for the scheme.
TikTok tested the alerts in Texas last year, which saw 20 million views.
The move follows on from similar features by Facebook, Instagram and apps such as Uber and Waze.
TikTok has been investing in child safety features recently, partnering with NSPCC to provide tips on usage habits and developing tools to restrict content viewed by teenagers.
