National Registration Act 1939


The National Registration Act 1939 was an Act of Parliament in the United Kingdom. The initial National Registration Bill was introduced to Parliament as an emergency measure at the start of the Second World War.
The Act established a National Register which began operating on 29 September 1939, a system of identity cards, and a requirement that they must be produced on demand or presented to a police station within 48 hours.

Importance of the 1939 register

The register is particularly important for genealogists because:
The lack of both the 1931 and 1941 census means that the Register provides the most complete survey of the population of England and Wales between 1921 and 1951, making it an invaluable resource for family, social and local historians. In fact, until the 1921 census is available, the 1939 Register is the most complete publicly available detailed record of the population of England and Wales since 1911.

Second World War Identity Cards

Every man, woman and child had to carry an identity card at all times and the cards would include the following information:
The register differed from the decennial census in a number of ways, one of which was the place of birth was not recorded, and the second was that the register was meant to be a living document. Hence, perusal of the register shows that maiden surnames have been replaced by married surnames when registered persons later married.
65,000 enumerators across the country delivered forms ahead of the chosen day. On Friday 29 September 1939, householders were required to record details on the registration forms. On the following Sunday and Monday the enumerators visited every householder, checked the form and then issued a completed identity card for each of the residents. All cards at this time were the same brown/buff colour. Some 45 million identity cards were issued. The estimate of the population of England and Wales for 1939 was 41.465 million exclusive of army, navy and merchant seamen abroad,, and some sources record the register as so the figure of 45 million may include the members of the armed forces abroad or in Scotland.
Three main reasons for the introduction of the identity cards were:
The more commonly found blue version of the identity card was issued in 1943 for adults. Until then, adult identity cards had been brown, the same colour as children's cards. Government officials had green ID cards with a photograph whilst those in the armed services had separate identification cards.
Children under 16 were issued with Identity Cards but they were to be kept by their parents.
Identification was necessary if families were separated from one another or their house was bombed, and if people were injured or killed.
The sections in the card showing the change in address were important, as many people moved several times during the war.

Class Codes

Class Codes were used for administration and electoral purposes. Cards were marked A, B, C, N or V.
Additionally, all class code 'B' cards were followed by three numbers. The first two indicated the year in which the holder was born whilst the third indicated which quarter of the year the holder was born in. For example, B. 252 would show that the holder was born in the second quarter of 1925 and would also indicate to a polling clerk that the holder would attain adult status in the second quarter of 1946.
Temporary buff cards were issued to children under 16 but did not carry a class code.

Repeal of the Act

On 21 February 1952, it no longer became necessary to carry an identity card. The National Registration Act of 1939 was repealed on 22 May 1952. The last person prosecuted under the Act was Harry Willcock. Even after the National Registration system was abandoned in 1952, the National Registration number persisted, being used within the National Health Service, for voter registration, and for the National Insurance System.

Access to information

The records created under the National Registration Act are held by The National Archives but were not freely accessible to the public for many years. From 2010, subject to restrictions to safeguard the privacy of people who are or may still be living, information could be obtained from the NHS Information Centre about specific individuals for a fee. The National Archives has now entered into an agreement under which the original documents for England and Wales have been digitised and scanned and are available on the subscription-based Findmypast and Ancestry.com websites. The digital images can also be viewed at The National Archives themselves in their reading room.
