Address data in corporations data base is generally messy and not in a structural form because in Turkey there is no standard to form an address. This situation resuls in many undelivered mail returns and of course puts a hidden but big cost for companies producing client documents in batch like banks, telecomunication and insurance companies. For logistic companies, address complexity makes their distribution planning almost impossible. Besides, unstructural address data prevents producing reports in analitic CRM.
People in big cities usually don’t know or either don’t care district name where they live. Sometimes address is specified as giving a direction and telling a neighbourhood which is only a contextual information but not a structural part of address data. These type of addresses result in an unreliable and difficult to analyse database. Definition of neighbourhood changes from one to another and it does not have any boundaries either. Istanbul Taksim, Karakoy or Ankara Kızılay are some good examples for neigbourhoods in Turkey.
People when giving their addresses, sometimes use borough and district names which are close and socio-economically better than actually they live. This contributes problems for mail/post distribution companies, logistic and execution proceedings. Unfortunatelly because of these problems it is not possibel to carry out residental based analytical CRM or planning.
