CPV code 85312400 designates Welfare services not delivered through residential institutions in the Common Procurement Vocabulary (CPV 2008), the EU classification used to describe the subject of public contracts.
85312400 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 85312000 (Social work services without accommodation).
