Geocoding

 Hi,I have a problem with the address geocoding.

I'm using the function SDO_GCDR.GEOCODE but in some case, even if i give the correct street name, municipality and province, the geocoding returns a wrong postal code.

this is an example:

SELECT SDO_GCDR.GEOCODE('GEO',

                             SDO_KEYWORDARRAY('VIA POLIFEMO 50061',

                                              'FIESOLE',

                                              'FI'),

                                              'IT','DEFAULT')

FROM dual;

-------------------------

MDSYS.SDO_GEO_ADDR(0),NULL,'Via Polifemo',NULL,NULL,NULL,'Fiesole','FIRENZE','IT','42020',NULL,'42020',NULL,'101','POLIFEMO','VIA','T','F',NULL,NULL,'L',0,75790319,'?????ENUT?B281CP?',3,'DEFAULT',11.36529,43.78511,'???12101010??004?')

        

The geocoded address contains then correct street name, municipality and province, but an incorrect postal code.
