# Age Estimation Check

### About service

The Age Estimation Check uses **liveness detection** and **facial analysis** to estimate a customer’s age from a selfie.

It’s built for **age verification** and **age-gating** flows. It requires only a selfie, with no document capture.

We recommend running this type of check through our [Hosted Solution](https://app.gitbook.com/s/lv7UhJvTbxeq4s3KwQpn/web-integrations/hosted-solution-quick-guide), [Web SDK](https://app.gitbook.com/s/lv7UhJvTbxeq4s3KwQpn/web-integrations/web-sdk-quick-guide), or native [Mobile SDKs](https://app.gitbook.com/s/sw26JqCBnT6AEIbxAYyk/quick-guides/mobile-sdk-guide). These SDKs guide your customers through the capture process, aiding them with completing the flow successfully with minimal friction.

### Common use cases

Use Age Estimation when you need a fast, low-friction **age check**:

* **Youth safety enforcement**: Apply age threshold validation to protect minors and support platform safety controls.
* **Access control for age-restricted services**: Confirm age before granting access to restricted content, platforms, or communities.
* **Age-gating for restricted products**: Verify age eligibility for regulated goods.
* **Gaming onboarding**: Validate age requirements during registration for gaming and related services.

### Analysis performed

The Age Estimation Check applies biometric analysis to confirm **live presence** (anti-spoofing) and generate a **selfie-based age estimation**.

The diagram below outlines the key analysis categories.
