How to look for Certificates of British citizenship 1949-1986
The National Archives holds many records relating to British nationality applications and citizenship registrations made prior to 1986. For records after 1986, contact UK Visas and Immigration.
As part of this collection, we hold office copies of certificates of British citizenship issued by the Home Office under the British Nationality Act 1948. We can supply two types of copies of individual certificates.
Types of copy
A photocopy or digital image produced for research purposes.
A photocopy which is authenticated by us as a copy of a public record and stamped with the seal of the Public Record Office. It can be used in evidence in legal proceedings in place of the original record.
Please note that a certified copy from The National Archives is not confirmation of the authenticity of the information shown on it. It is not evidence of identity and should not be used as evidence of the event.
What information will it contain?
Certificates may include details such as address, occupation, spouse, children and parents, but only until 1973. After 1973, certificates may just include full name, date of birth and date of issue.
The level of detail on a certificate depends on the Act under which it was issued. For more information about this, see the catalogue description of HO 334 in Discovery, The National Archives’ catalogue.
