The cadastral reference is a compulsory code in Spain that is used to identify a property.
It is a set of 20 characters made up of numbers and letters that are unique for each property. The first seven numbers tell which parcel of land it belongs to, and the next seven characters reveal on which sheet of the plan it is located. The next four indicate where the property is within the finca and the last two are control characters to verify that the rest are correct.
For rural dwellings, the cadastral reference is slightly different, but works in the same way, with each group of characters identifying a part of the location of the property.
Cadastral data is of the utmost importance when buying, selling or inheriting a property, as this code makes it possible to know exactly which property is involved. This increases legal certainty and helps to prevent fraud.
