The fifth state kids code, and the harshest: effective the day it was signed, treble damages, and personal liability for employees.

Current position

In force since Feb 2026; NetChoice challenge filed

What it does

Signed February 5, 2026 and effective immediately, with no cure period. Covered online services must exercise reasonable care in design and in their use of minors' data, undergo annual third-party audits with public reports due each July 1, and face treble damages for violations. Officers and employees can be held personally liable for willful violations. NetChoice has already filed suit.

Why it matters

The earlier kids codes gave companies a runway; South Carolina's switched on at the governor's signature. Personal liability for named employees is new to this fight, and it changes who feels the pressure: not the platform, the person. Add it to California, Maryland, Vermont, and Nebraska and the design-code map now runs coast to coast through both parties.

Our take

The versions get harsher state by state. South Carolina skipped the grace period, tripled the damages, and pointed the liability at individual employees. The mechanics underneath have not changed: to give minors the safe version, the service has to sort every visitor by age.
