What is the difference between age verification and age assurance?

Age assurance is the broad term for any method that gives a service confidence about a user's age. Age verification is one method within it that confirms age with evidence such as an ID. Age estimation is another, which predicts age from a face.

Is facial age estimation safe for kids?

It depends on the service. Read what it does with the photo, whether biometric data is kept, who runs the check and whether there is an ID or parent alternative. Check the service's own help pages for current details.

Do age checks store my child's face?

Some services say they delete images after processing and do not keep biometric data, but practices vary. Always read the service's privacy information.

Can a free age test replace an age check?

No. A free age test only estimates how old a face looks, and no platform accepts it as proof of age.

Q: How do online age checks work?

A service may ask you to take a selfie for an age estimate, upload an ID, or have a parent confirm your age. Many combine methods, using an estimate first and asking for ID only if the estimate is close to a limit.

Read verification vs estimation

In short

Age assurance is the umbrella term for any method a service uses to be confident about a user's age, including estimation, verification and parental confirmation.
Age estimation guesses age from a face; age verification confirms it with evidence such as an ID.
Parents should look for what happens to the photo, whether biometric data is kept, who runs the check and whether alternatives exist.
A free age test cannot replace an official age check.

Games, social apps and websites increasingly ask users to prove or show their age. If you are a parent or guardian, the vocabulary can be confusing: age verification, age estimation, age assurance. This guide answers the question "what is age assurance?" in plain language and explains how to think about the checks your family may meet.

What is age assurance?

Age assurance is the umbrella term for any method a service uses to be confident about how old a user is. It is not one technology. It is a family of approaches, and services often combine them.

The three main approaches

Approach	How it works	Uses a document?
Age estimation	A model estimates age from a face, often a selfie	No
Age verification	The user proves age with evidence such as an ID	Yes
Parental confirmation	A parent or guardian confirms age or gives consent	No, it relies on the parent

Age estimation

A model predicts an age or an age group from a face. It is quick, and it can work without any document. It is also approximate. Read how AI age estimators work for the technology.

Age verification

The user proves their age with evidence, such as a government ID. It is more certain than an estimate, but it asks for more personal information.

Parental confirmation

A parent or guardian confirms the age or gives consent, particularly for younger users. Details vary by service and region.

How do online age checks work in practice?

A typical flow looks like this:

A service asks you to check your age to unlock a feature such as chat or certain content.
You choose a method, such as a selfie estimate or an ID.
The service or a partner runs the check.
The service applies the result to the account.
If the result looks wrong, there is usually another route, such as an ID check.

Many services combine methods, using an estimate first and asking for an ID only when the estimate is close to a limit or the user disagrees.

Why do services use age assurance?

The stated aim is to give younger users age-appropriate experiences, such as limits on chat and content. Requirements also come from laws and platform policies in some places, and they change over time. As a parent, the best source for what a service does is the service's own help center.

Estimation is not proof

An estimate is a guess with an error margin. Someone close to an age limit can land on either side of it. That is why an ID or a parent's confirmation is usually the fallback. Our guide on face age verification vs estimation explains the difference in detail.

What parents should check in any age check

What happens to the photo or video? Is it deleted after processing, and how quickly?
Is biometric data kept? A stored face template is very different from a one-time estimate.
Who runs it? A named third party with its own privacy policy, or the service itself.
Are there options? Can a user choose an ID or a parent instead of a selfie?
Can a wrong result be corrected? There should be a clear path.
Is it appropriate for your child's age? Some steps need parental consent.

Talking to children about age checks

Explain why the check exists in simple terms: it helps keep younger players safe. Make it clear that the honest answer is always the safe one, and that they should never use tricks to pass a check. Agree that they will tell you if something looks odd or a service asks for more than they expected.

A real example

Some platforms give players a choice between a selfie estimate and an ID. We explain one publicly documented example, based on its own Help Center, in our Roblox face age check guide. We are not affiliated with any platform, and their rules can change, so always check the current help pages.

What is a selfie age check?

A selfie age check is one form of age estimation. You take a live selfie or a short video, a model estimates how old you look and the service places you in an age group. It is not face recognition, and it does not need to know your name. It is usually quick, and most services offer an alternative, such as an ID check. For the step-by-step version, read selfie age check: what to expect.

How can parents help with online age checks?

Parents can help in several ways. Read the service's own explanation before a child starts, sit with younger children during the check, and explain that the honest answer is the safe one. Use official apps and websites only, and turn on parental controls where a service offers them. Talk about privacy: what a photo is used for and who can see it. If a check gives a wrong result, look up the correction route in the service's help center rather than trying workarounds.

Free age tests are not age checks

Tools like our face age calculator estimate how old a face looks for fun. They are not accepted as proof of age, and they are not connected to any platform. Do not treat their results as verification, and do not use them to try to bypass a check.

Privacy and safety tips for families

Use official apps and settings when a service asks for age information.
Be careful about sites that ask for an ID or selfie unrelated to a service you use.
Read the privacy policy of any age check provider.
Use strong passwords and parental controls where they are offered.

The takeaway

Age assurance is the umbrella term for any method a service uses to be confident about a user's age. Estimation guesses, verification confirms and parental confirmation relies on a guardian. Check what happens to the photo, whether biometric data is kept and what the alternatives are, and remember that an estimate is not proof of age.
