FDI (First Day of Issue) Postmark

The First Day of Issue postmark appeared for the very first time in slogan form in 1963, followed by a circular postmark for the 1964 Shakespeare stamps. Strictly speaking the term “FDI postmark” should only be used to describe postmarks sponsored by Royal Mail but the term is often more widely used to cover any cover with a pictorial postmark dated on the first day of a new set of stamps. Royal Mail reserve the right to the wording “First Day of Issue” so you will never find these words in a sponsored British postmark.
