About postcodes

When searching using a postcode, your results depend on the type of postcode used in the
country that you are searching in.
The following types of postcodes are used:
Postcodes that navigate you to a street or part of a street.

Postcodes that navigate you to an area comprising, for example, a single town, several

villages in a rural area or a district in a large city.
Postcodes for streets
Countries such as the Netherlands and the United Kingdom use this type of postcode. When you
search using this type of postcode, enter the postcode, then leave a space and then optionally
enter the house number. For example, "1017CT 35". Your device then plans a route to a specific
house or building on a specific street.
