The cadastral number provides details
The cadastral number can be used in Spain to identify properties such as houses, buildings or plots of land, etc. It is a public, official entry that can be accessed by anyone and consists of an alphanumeric code of twenty digits. It is unique throughout the country and relates to each individual property. The cadastral number is comparable to the Spanish DNI.
The cadastral number is required when applying for energy services, for example for electricity, gas or water connections. However, the number is also required for legal transactions relating to real estate, for example if you want to rent, buy or sell a house or apartment.You can use this information to call up the full details of the property in the land register; you will receive information about the year of construction, the floor plan and the exact dimensions.
The cadastral number is assigned by the land registry (Catastro). The land registry is responsible for the statistical recording of all properties in a city. This information can usually be found on the Internet on the official website of the land registry. This is:
