CPV code 70340000 designates Time-sharing services in the Common Procurement Vocabulary (CPV 2008), the EU classification used to describe the subject of public contracts.
70340000 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 70300000 (Real estate agency services on a fee or contract basis).
