Each year on 9 October, the world celebrates World Post Day, marking the anniversary of the Universal Postal Union’s founding in 1874. Declared by the 1969 Universal Postal Congress in Tokyo, this day highlights the vital role that postal services play in connecting people, communities, and businesses across the globe. It also recognizes the Post’s contribution to global social and economic development—facilitating communication, exchange, and a sense of connectedness, even in the most remote corners of the world.
In the history of South Africa’s Antarctic involvement, the Post holds a unique place. A post office was established on Marion Island by Alan Crawford, symbolizing the enduring human desire to communicate across vast distances. Over the years, SANAP post envelopes have become cherished pieces of heritage—capturing moments of exploration, scientific achievement, and collaboration. These envelopes, adorned with distinctive stamps and postmarks, reflect not only the spirit of discovery but also the shared legacy of all who have contributed to South Africa’s polar story.
