CPV code 79624000 designates Supply services of nursing personnel in the Common Procurement Vocabulary (CPV 2008), the EU classification used to describe the subject of public contracts.
79624000 is a leaf code — the most specific level of its branch — so it can be used directly as the main CPV code of a contract notice. If it does not quite fit, check the neighbouring codes under 79620000 (Supply services of personnel including temporary staff).
