Not really relevant to the topic at hand, but interestingly the UK doesn't really have any national ID number valid for both children and adults. The only one is the NHS Number but that's not used outside of a medical setting. Additionally my birth certificate isn't digitised. It was handwritten with a fountain pen by the local register office. For most intents and purposes, the central government didn't know I existed until I hit 16 and signed up for a National Insurance number.
