This guide provides a brief overview of Second World War records held at The National Archives.  These are the records of central government, including all branches of the military. You’ll get a sense of the sort of records we hold and links to guides with more details and advice on how to find the records in our collection, including whether records are available online.

How the records are arranged

The original records are arranged at The National Archives by the government departments that created them. Each department’s collection of records is identified by a department code. Three of the most significant for Second World War research are:

Numerous other government departments have transferred Second World War records to The National Archives. You will find details for many of them in the guides which we provide links to below.

How to search for records

Before you begin a search you should see if there is a guide to the records you are looking for – this guide is designed to help you to do that. Each guide listed below contains the links and advice you will need to search a specific set of records.

Each guide will indicate whether records have been made available online (charges usually apply). The online copies are accessed either directly from our website or from the websites of our licensed partners, including Ancestry and Findmypast.

Some records have no online version and to see these you will need to consult them at our building in Kew or pay for copies to be made and sent to you. The search for records held at Kew begins by using keywords and dates to search our online catalogue. The catalogue contains short descriptions of the records and a document reference for each – you will need the document reference to see the record itself or to request copies.

For more guidance on searching or browsing our catalogue, visit our Discovery help pages.

Records of individuals

Military and intelligence

The service record of an individual will usually provide more detail on them than any other single record. However, you can use operational records of the units they served with to paint a broader picture of service (see next section for advice on operational records). Military service records of the Second World War, including those for servicewomen and military nurses, are still held by the Ministry of Defence. Visit the GOV.UK website for further information.

In general, the identities of individuals who worked for the security and intelligence services are protected and therefore records of them are not made available to the public. For more information read our guide to records of the intelligence and security services.

For other records at The National Archives which relate to individuals who served with the military during the war, read our guide to records of deaths in the First and Second World Wars, which includes advice on finding casualty lists, as well as our guides to records of medals and honours, courts martial and prisoners of war.

Merchant Navy

We hold relatively detailed records of merchant seamen who served during the Second World War and records of their service medals.

Home Front

Records of individuals on the Home Front include the 1939 Register, Home Guard, the Women’s Land Army and some records relating to conscientious objectors.

Our guide to refugees includes links to records of passengers, aliens’ registration and naturalisations.

We also have a guide to finding records of internees.

Although The National Archives has government records of policy regarding evacuation, no central records of evacuees were kept. Our guide to evacuees gives some advice and links which may help you to find information from other sources.
