List of British postage stamps

This is a list of postage stamps issued by the United Kingdom, normally referred to as Great Britain in philatelic usage, even though standard British stamps are valid alongside their regional counterparts throughout the British Isles. This list should be consistent with printed publications, and cite sources of any deviation (e.g., magazine issue listing newly found variations).

Note: Issues between 1962 and 1966 inclusive are available in two varieties – with, and without, phosphor bands (which fluoresce in ultra-violet light). These were introduced to help sorting machines distinguish between first and second class letters automatically and the early examples with phosphor bands (up to the 1965 Salvation Army issue) are worth several times those without.

Note: First commemorative set to feature in an illustrated Presentation Pack, including mint stamps, with descriptive notes and protective covering. Also first set for which there was an official Post Office issue illustrated First Day Cover envelope and first set to commemorate a person from history.

Also this year, in two issues, the first Machin definitives (4d, 1s, and 1/9d in the first issue); the remaining values were issued later in 1967 (3d, 9d, and 1/6d) and on two dates in 1968.
