OBS_VALUE: Size (i.e. surface) and population are determining factors, depending on different regions and distance-from-centre criteria. Generally, for large municipalities of a population of more than 100.000 people and within a 20km radius from the centre, there needs to be an audit/examination before the granting of the licence, but this is not required for the greater area of Attiki (which includes Athens) and Thessaloniki, the two largest municipalities.More specifically, whenever required, licences are granted by local Authorities according to the Code of Municipalities and the Market Regulations Code. Authorization is granted after considerations about population, economic needs, competition and urban planning.
