The changes aim to modernize services, improve customer experience, and enhance tracking and security. Services like registered small packets, surface/air small packets, surface letter mail, and SAL letter mail will cease. This move promotes more efficient, reliable, and trackable alternatives, reflecting global e-commerce standards and decisions by other postal administrations.
