In our city ranking we list special sub sets of the usual well know ZIP codes. What is it all about?
A ZIP code is part of an address to route the letters and parcels to a specific address. Beside this main purpose sometimes the people
try to find out what kind of area is defined by a given ZIP code. Especially when you want to know, WHO is living under this ZIP code.
You want to buy or rent real estate and need to know something about the neighbourhood
A bank needs to know, where a creditor is living
Is this location industrialized (noisy/smelly)?
There are only few ressources in the internet which can tell you something about the quality of a ZIP code and as far as we know, they all are charging you with fees.
We can give you these information here for free. This is how we describe the ZIP codes (compare it with the example Paris):
We have used our huge database of all big companies in Europe which includes their ZIP codes and NACE codes.
We have looked for EVERY ZIP code in Europe, if there are the head offices of big companies located
So we have now a list of ZIP codes, where big companies, manufacturing companies and servicing companies are residing
If we found more than 5 companies at a specific ZIP code (or range of codes) we made them bold
If we found more than 20 companies at a specific ZIP code (or range of codes) we increased the font
If we found more than 50 companies at a specific ZIP code (or range of codes) we made them bold and increased the font
but if we found only one or two companies with this ZIP code, the ZIP code is probably not correct described by the activties of these companies. So we set the ZIP code in a smaller font.
