What is the NATO Codification System?

The NATO Codification System (NCS) is a vital component of NATO's supply chain management, providing a standardized and efficient method for identifying and tracking military supplies, equipment, and other materials. By utilizing the NCS, NATO and its member countries can ensure that the right supplies and equipment are available when and where they are needed, improving the readiness and effectiveness of military operations.

The NATO Codification System enhances interoperability among user countries. It aims to ensure any article or item is identified through a single denomination and a unique NATO Stock Number (NSN).

By implementing the NATO Codification System we are increasing the effectiveness and efficiency of the logistics support systems.

Para todos los contratos de adquisición de materiales que formalicen las Fuerzas Armadas españolas, el Ministerio de Defensa establece que es obligatorio considerar la catalogación de los mismos como paso inicial para su posterior gestión logística, lo que se exige de los contratistas nacionales y extranjeros.
