How Age-Check Systems Work

Three steps that happen in milliseconds when you visit an age-restricted site

1 🔍

IP Lookup

The site captures your IP address and queries geolocation databases to determine your country, region, and ISP.

2 📍

Geolocation Check

Your IP-based location is compared against jurisdictions with age-verification laws to determine if checks are required.

3 🛡️

VPN Detection

The system checks if your IP belongs to a VPN, proxy, or datacenter — flagging potential circumvention attempts.

Frequently Asked Questions

It depends. While a VPN changes your IP address, many age-verification systems now detect VPN usage by checking if your IP belongs to a known datacenter or VPN provider. If your IP is flagged as a datacenter IP rather than residential, the system may block access or request additional verification. Under Utah's SB73, websites are legally required to implement these checks.

IP reputation is a score assigned to an IP address based on its history and characteristics. Age-verification systems use databases that track whether an IP has been associated with VPN services, spam, fraud, or datacenter hosting. A poor IP reputation can trigger additional verification steps or outright blocking.

Usually not. Datacenter IPs are one of the primary signals age-verification systems check for. Most VPN and proxy services use datacenter IPs, which are easily identified through ASN databases. Some premium VPN services offer residential IP addresses, but these are less common and more expensive.

Age verification systems based on IP analysis have limitations. They can determine your approximate country and whether you're using a VPN, but they cannot directly determine your age. They are most effective at enforcing geographic restrictions and detecting circumvention attempts. False positives can occur, especially for users on business networks or shared IPs.
