Age assurance methods in Ireland

Age assurance is an umbrella term, not one technology. Irish services should identify the applicable age-related risk and choose a method that is effective, proportionate, privacy-preserving, accessible and supported by redress.

For: platform, trust-and-safety, product, privacy and procurement teams. This is independent information, not legal, compliance or security advice.

Method ladder

Method	Output	Main caution
Declaration	User-stated age/date	Weak where reliable restriction is necessary
Inference	Age band inferred from existing signals	Opacity, profiling and error
Estimation	Predicted age or band	Threshold uncertainty, fairness and fallback
Verification	Age checked from identity evidence	Oversharing and document exclusion
Reusable proof	Signed over-threshold or band result	Issuer trust, device access and unlinkability

Choose from the purpose

1. Identify the specific risk, legal trigger and threshold.
2. Decide whether exact identity or birth date is genuinely necessary.
3. Select the least intrusive method effective for the purpose.
4. Provide equivalent alternatives for people who cannot use the default.
5. Measure errors, appeals and real protective effect.

Privacy and user protection

• Minimise disclosure to an age result where possible.
• Do not reuse age-proofing data for advertising or unrelated profiling.
• Separate issuer and relying-party knowledge where the architecture permits.
• Publish retention and deletion.
• Explain decisions and provide a timely appeal or alternative route.

Irish implementation questions

Monitor Coimisiún na Meán decisions, DSA implementation, relevant sector law and whether Ireland adopts or recognises an EU blueprint implementation. A platform announcement is not proof that one method is legally required across every Irish service.

Evidence and limits

MyID separates enacted rules, official implementation material, testing and vendor claims. A source can establish what its publisher says; it does not prove that every product, deployment or interpretation works as claimed. Where Irish implementation remains unsettled, this page says so.
