What ZIP odes are there in the vicinity?
ZIP code tool for vicinity search all Europe
You know that the best orders come from zip code "A". So it seems like a good idea to write to all the consumers
or companies that live or have their headquarters in that area. Just enter the zip / postcode or the name of the town / city and
the distance. Then you will get all the zip codes within this radius.
In this way you have optimised your target group according to an important criterion, e.g. for surveys, questionnaires, advertising campaigns, sales districts.
