The Helsinki metropolitan postal code areas have been produced together in a joint effort with the cities of Helsinki, Espoo and Vantaa. The data contains precise territorial borders and information on the postal code and place of business.

The postal code territorial borders have been produced based on the municipalities' own borders and therefore they are compatible with the municipalities' own postal code territorial borders.

The accuracy of this combined dataset differs by municipality. This is caused by the initial data and administration procedures.

This dataset is produced each year on January / February.
