Thanks for explaining what the 1939 register was. So only if you were born prior to 1940 would you have one of these cards, is that correct?  But you would have been expected to be able to produce it until 1952 if asked by police? Jane Subject: Re: [LAN] What is the 1939 Register ? I didn't see in any of the messages on this topic what the 1939 register is. What was it created for and what does it contain. Was this something that was only done once or are there other years? <<snipped>> See http://en.wikipedia.org/wiki/National_Registration_Act_1939 and http://www.hscic.gov.uk/register-service But it's a one-off.
