Over 20 countries have passed or are moving toward age limits on social media for under-16s, including Australia, Indonesia, Malaysia, France and the UK. Vietnam has a draft decree requiring parents to register children's accounts and platforms to verify ages. For a Thai business, this mainly matters if you sell to children or run a kids' brand, app or content channel, or market through social platforms that may need age checks. No action is needed yet; watch for a Thai rule following the same path.
