UPU Think Tank Brief No. 2/2025 – thinktank@upu.int – www.upu.int Enhancing e-commerce customer experience – exploring the hidden role of addressing New econometric evidence from the Universal Postal Union (UPU) reveals the stark reality of address inaccuracy's impact on global postal delivery. Drawing upon Insights from UPU’s big data platform and based on checks performed with the POST*CODE® API1, our analysis shows that postal operators worldwide can increase their successful first delivery attempts by up to 23% by improving address accuracy–with a median improvement of 5.4% across all operators. Conversely, poor address quality reduces delivery success rates by as much as 14%. As cross-border e-commerce continues its exponential growth the proliferation of non-standardized addressing threatens the very foundation of global e-commerce. The solution is simple - an urgent standardization effort, under the aegis of the UPU, to prevent addressing chaos from undermining the postal sector's ability to serve the digital economy. Quantifying the address accuracy crisis Big data reveals the true impact For the first time, a comprehensive econometric analysis—using big data from postal operators worldwide and POST*CODE® l reference data—has quantified the link between address accuracy and successful delivery rates The findings are striking: address quality emerges as one of the most significant determinants of first delivery attempt success rates across the global postal network. Our data analysis reveals three distinct categories of impact, with high-performing operators achieving improvements of 2% or 1 The POST*CODE® API is a service provided by the UPU that enables address verification based on more in successful delivery rates through address accuracy (shown as green bars in Figure 1, overleaf). The best performers can expect increases of up to 23%. This extraordinary range demonstrates that address quality is not a marginal operational concern but a fundamental driver of postal performance. Moderate performers still, shows in yellow bars, see meaningful improvements of up to 2%. And a concerning number of operators experience negative impacts from poor address handling (shows as red bars) with delivery success rates declining by as much as 14%. The median effect across all operators—a 5.4% improvement in successful first delivery attempts—represents millions of packages delivered successfully rather than requiring costly redelivery attempts or returns. In the context of global e-commerce volumes, even a single percentage point improvement translates to enormous economic value and customer satisfaction gains. Distribution tells a story The distribution of postal operators across the impact spectrum reveals crucial insights about the global postal system's readiness for the digital age. The majority of operators cluster around moderate positive impacts, suggesting that basic address accuracy improvements yield consistent b
