Common Procurement Vocabulary (CPV) has been developed by the European Union for public procurement.
CPV codes are a standardised vocabulary to describe procurement notices to help procurement-responsibles to classify procurements consistently, and to help service and product suppliers find procurements of interest.
An example for a CPV code is
71356200 Technical assistance services
CPV codes have the form "Number Description", where Number consists of 8 digits. The textual description depends on the language used, but the number is identical for all languages.
CPV was established by Regulation (EC) No 2195/2002 of the European Parliament and of the Council on the Common Procurement Vocabulary (CPV).[1]
