Almost every major social platform sets its minimum age at 13 — Instagram, TikTok, Snapchat, YouTube's full app, and X all state 13 in their terms, a threshold that comes from the Children's Online Privacy Protection Act, COPPA, which since 2000 has required parental consent for accounts of children under 13. Some platforms go higher: WhatsApp states 16 in much of the world, and Discord requires users to state they are 13 or older with some servers setting higher limits. Enforcement is mostly the honor system — a self-reported birthdate at signup.
The Offspring Session publishes information, not legal or parenting advice; whether a child is ready for a platform is a family decision no article can make.
Why is 13 the magic number?
Because Congress wrote it into COPPA in 1998. The law restricts data collection from children under 13 without verifiable parental consent, which made pre-teens commercially complicated for ad-supported platforms — so 13 became the industry-wide floor. The Federal Trade Commission, which enforces COPPA, has brought cases against platforms that knowingly allowed younger children, including a record $170 million YouTube penalty in 2019. That case also changed YouTube's product: it created the under-13 experience YouTube Kids and restricted data collection on child-directed content, per the FTC's order.
What does each platform actually say?
Minimum ages as stated in each platform's terms (as of August 2026, subject to change):
| Platform | Stated minimum age | Parental supervision feature |
|---|---|---|
| 13 | Supervised accounts for teens | |
| TikTok | 13 (full features 16-18) | Family Pairing |
| Snapchat | 13 | Family Center |
| YouTube | 13 (YouTube Kids younger) | Family Link supervision |
| Discord | 13 (varies by region) | Limited; server-level controls |
| Messenger Kids | No minimum (parent-managed) | Entirely parent-managed |
Regional law layers on top: the U.K.'s Age Appropriate Design Code and the EU's data-protection rules push some platforms to 16 in those regions, and several U.S. states passed their own parental-consent laws for social accounts in 2023-2025, now in litigation.
How is the age checked, really?
Mostly it is not. Signup asks for a birthdate and accepts the answer; platforms state in their terms that false information violates them, and some use age-estimation or ID checks in specific cases — dating features, live streaming, or when an account is flagged. The FTC's COPPA enforcement, including updated rules proposed in 2024-2025, presses platforms toward stronger verification, but the practical reality today is self-declaration. That reality is why family conversation matters more than the stated number.
What do the experts recommend?
The American Academy of Pediatrics does not set its own platform-age number; its media guidance recommends delaying social media until children can handle its interpersonal demands, and its 2023 policy statement on social media use in youth suggested roughly 14 or later as a reasonable family target while emphasizing readiness over age. Common Sense Media's research has documented that large shares of children have accounts before 13. Those are the expert and research positions; readiness differs by child, which is the family's call.
What are the alternatives for younger kids?
Managed options exist below 13: Messenger Kids is parent-managed with approved contacts; YouTube Kids restricts content and data collection; and many family devices support full parental-control layers through Apple's Family Setup or Google Family Link. These give communication and viewing with consent structures built in — trade-offs between protection and learning independence that each family weighs itself.
What is changing?
Two threads worth watching. FTC rulemaking on COPPA has been moving through 2024-2025 with stronger verification requirements in play. And a cluster of state parental-consent laws — Utah's, Arkansas's, and others — are in various stages of litigation, with courts split on First Amendment grounds. Neither thread is settled; platform terms and state rules can both move, so check the platform's own terms page when the decision gets real.
What the terms show is a 13-year floor inherited from a 1998 law, checked mostly by self-report. What experts recommend is readiness over age. When your child actually joins is your call — made better knowing both.
