The 2017 Extraordinary Congress in Ethiopia codified Postal Security under the UPU Convention to establish the minimum security standards required for designated operators. This is to protect the postal system and protect the supply chain for worldwide commerce and assure sustainability for the sector.

Convention Article 8.1
Member countries and their designated operators shall observe the security requirements defined in the UPU security standards and shall adopt and implement a proactive security strategy at all levels of postal operations … This strategy shall include the objectives defined in the Regulations, as well as the principle of complying with requirements for providing electronic advance data on postal items… The strategy shall also include the exchange of information on maintaining the safe and secure transport and transit of mails between member countries and their designated operators.
