boundary=postal_code, when used on a relation and member ways, can be used to specify a dedicated type=boundary area with a consistent national postcode.

This tag should not be used in countries where a postal code does not represent a precise area (for example, in the United States). It also may not be verifiable in many countries.

How to map

On the relation:


On member ways making up the relation†:


† When a way is being shared as an administrative boundary relation (boundary=administrative), and a postal code boundary relation, tag that member way with boundary=administrative. Both boundaries types are implied.

This kind of postal mapping is widely used at least in Germany and Belgium.
