What is the product user licence?

This is the document containing the requirements to be met by the contracting party to use the product:

  • The contract takes effect upon payment and lasts for one year.
  • To renew, simply inform Correos and follow the standard procedure.
  • The contracting party may only use the information to update their own database or to improve the quality of postal addresses in their systems.
  • The product may not be sub-licensed and a Post Code search tool cannot be built for access by users unrelated to the business of the contracting party.
  • The contracting party undertakes to encrypt and protect the information using suitable technical and security measures.

Is it important to renew the licence every year?

Correos collects all updates on new streets, extended sections, Post Code coverage changes and geopolitical changes every day, presenting them on a quarterly basis. The information varies considerably from one year to the next, so we recommend renewing the product.

What are the advantages of the Plus product over the Basic product?

It offers an updated structure and more content on the identification of towns/cities and their INE information.

It also includes socio-demographic indicators and a wide range of co-official and colloquial names for towns/cities.

What is the Cartographic Overlay used for?

It provides spatial boundaries for each Post Code, allowing adjustment to any kind of national political map. This is highly useful when geo-referencing and analysing spaces, producing heat maps or qualifying the national population.

What happens when the licence expires and I do not renew?

The information will become obsolete and out-of-date, meaning you will be unable to lodge any complaints with Correos. We would also cease providing support and advice.
