Postal stakeholders that are not public postal operators or regulators can add their voice to the UPU's deliberations through the Consultative Committee (CC). The Committee represents the interests of the wider postal sector and provides a framework for effective dialogue. The committee plays a key role in developing a more global vision of the issues affecting the sector. This role enhances the UPU's value to the industry and its effectiveness. The committee consists of non-governmental organizations representing customers, delivery-service providers, workers unions, suppliers of goods and services to the postal sector and individual and company organizations that have an interest in supporting the UPU's mission and objectives.
