This report benchmarks the situation of postal development around the world in 2020 – a crucial topic owing to the important role played by the postal sector in promoting socio-economic development. The analysis is based on the Integrated Index for Postal Development (2IPD), which draws on a wide range of postal (big) data from numerous sources to provide a composite picture of postal development in 170 countries. Switzerland tops the list, followed by Austria, Germany, the Netherlands and Japan, with the top 10 mostly made up of advanced economies. There are also encouraging results among regional leaders, such as Poland, Singapore, Tunisia, Brazil and Ghana. The report discusses the considerable impact of COVID-19 on the postal sector through the lens of the 2IPD. The analysis reveals that the reliability of the international postal supply chain has been re-established, after considerable disruptions in March and April 2020. Nevertheless, a major consequence of the pandemic is that the postal network is still less connected and far-reaching than it was a year ago. While the operators of most advanced economies appear to be resilient to the economic shock, in most developing countries the battle for the relevance of the sector is gathering pace.
