Yes. It is 100% legal to use a VPN in Missouri. In fact, since
Missouri 15 CSR 60-18 (the state’s strict online age-verification law) went into full effect in late 2025, many residents have adopted VPNs as a primary tool to protect their personal identity. This law requires websites with certain content to verify a user's age via government ID or third-party digital wallets. Using a VPN allows adults to protect their sensitive data from these third-party verification brokers. However, remember that VPNs are an online privacy tool, not a “laws don’t apply to me” cloak, so anything illegal without a VPN is still illegal with one.
