Age verification is no longer optional.

That doesn’t mean it’s easy.

The UK Government’s push for stronger online safety measures means age verification is rapidly moving from “nice to have” to essential.

The recent BBC coverage highlights just how quickly this is happening.

Under the Online Safety Act, platforms are now expected to implement robust age checks to prevent under-18s accessing harmful content. The methods vary – facial age estimation, identity document verification, credit card checks – but the direction of travel is clear.

Age verification is no longer a future problem. It’s a current one.

The Home Office is also investing in age estimation technology at the border, using photographs to help identify adults falsely claiming to be children. The distinction has significant implications for how people are processed and supported.

The challenge is that while the regulatory requirements are becoming clearer, the technology itself remains imperfect.

And that’s where things get interesting…

The technology is improving but it isn’t magic

Computer vision has advanced dramatically in recent years. Models are becoming faster, more accurate and more accessible. Technologies such as Meta’s Segment Anything Model (SAM) have accelerated what is possible.

But age estimation remains a probabilistic exercise. It is not a definitive answer. It is a prediction, and predictions come with limitations.

The real risks

Privacy and Data Handling

Most age verification solutions rely on sensitive personal information. That may be biometric data, identity documents, photographs or financial information, and with that comes responsibility.

Users are becoming increasingly cautious about sharing personal data, particularly when they don’t understand how it is being stored, processed or retained.

Poor implementation creates compliance risk, reputational risk and security risk. 

Trust matters and if users don’t trust the process, they won’t complete it.

Accuracy and Bias

Age estimation models do not operate in perfect conditions and are affected by lighting changes, camera quality and people presenting differently. Environmental factors influence outcomes. Small changes in image quality can significantly impact confidence scores and accuracy.

We’ve seen this ourselves deploying age estimation systems in live event environments where conditions are rarely ideal. The difference between a controlled test environment and the real world is often substantial.

Circumvention

No age verification system is impossible to bypass.

The internet has already demonstrated that people will actively look for ways around these controls. Whether that’s spoofing techniques, manipulated images or other workarounds, determined users will continue testing the limits of the technology.

The objective is not perfection but reducing risk to an acceptable level. That’s a very different engineering challenge.

Where Most Projects Fail

The biggest mistake organisations make is treating age verification as a compliance exercise. Tick the box, deploy the technology and move on.

In reality, successful implementations sit at the intersection of three areas:

  • Regulatory compliance
  • Technical capability
  • User experience

Ignore any one of those and the solution starts to fail. You can build the most accurate model in the world, but if users abandon the process you’ve solved nothing.

Likewise, a seamless user experience means little if it doesn’t satisfy regulatory requirements.

The organisations that will get this right are the ones that approach age verification as a product and operational challenge, not simply a technology purchase.

The Bottom Line

Age verification is becoming a requirement across more and more digital services. That trend is unlikely to reverse.

But there remains a significant gap between policy ambition and operational reality. Bridging that gap requires more than buying software. It requires understanding the limitations of AI, designing for real-world conditions, and building systems that people will actually use.

Because getting age verification working reliably in production is considerably harder than most vendors would have you believe.
