There were various British labels that issued Motown singles in Britain:
Motown was distributed by London American Records from 1960 to 1961
Fontana Records from 1961 to 1962
Then Oriole American Records from 1962 to 1963
And Stateside Records from 1963 to 1965
The official Tamla Motown Records label was then created in March of 1965. Releases in Britain were then handled consistently by one separate label, with its own numbering system and distribution by EMI. In some cases, the label released British-only singles and albums.
