The Common Procurement Vocabulary (CPV), as defined by the European Union, is a standardized coding system used to classify goods and services procured or sold by public bodies. It provides a standard reference structure for both buyers and sellers within the EU’s public sector procurement system. CPV codes are essential for public market participants looking to successfully provide and/or purchase the goods and services needed, as they facilitate a smooth and efficient flow of information when processing contracts. CPV codes allow potential bidders to easily identify each contract opportunity according to its category, while providing buyers with an efficient way to distinguish between tender responses.
