Before buying, selling, or simply learning more about a property, many people turn to the Virtual Cadastre, the online tool that allows users to access official data on any property in Spain for free. However, it is not always clear what information is available, how to access it correctly, or how it differs from other registries, such as the Property Registry.
The Virtual Cadastre is the online service provided by the General Directorate of Cadastre that allows users to view, free of charge, the physical, legal, and economic information regarding properties located in Spain. It is accessible through the Cadastre’s Electronic Portal without the need for in-person visits or paperwork.
The Cadastre’s Electronic Portal centralizes all digital services related to cadastral information: from basic inquiries to downloading certificates, filing declarations, or requesting data corrections—all available 24 hours a day.
Although they are often confused, the Cadastre and the Property Registry are separate agencies with different purposes: the Cadastre, under the Ministry of Finance, records the physical, economic, and administrative description of properties primarily for tax purposes, while the Property Registry, under the Ministry of Justice, legally protects ownership and the encumbrances on a property.
The Virtual Cadastre offers a comprehensive set of data on each property, some of which is freely accessible and some of which has restricted access.
The cadastral reference is the unique 20-character code that unambiguously identifies each property in Spain and serves as the starting point for most searches in the Virtual Cadastre.
For each property, you can view its address, its built-up area and lot area, as well as its intended use—whether residential, commercial, industrial, or other.
The Cadastre’s map viewer allows you to view a graphical representation of each parcel on a map, including its boundaries and the exact location of existing structures.
The Virtual Cadastre also allows you to view both the property’s cadastral value—used primarily to calculate the Property Tax (IBI)—and its reference value, which serves as the minimum taxable base for certain property transfer taxes.
While location, area, and cadastral value are publicly accessible data, other information—such as ownership status or the owner’s personal data—is protected and may only be accessed by the owner or by someone who can demonstrate a legitimate interest.
There are different levels of access depending on the type of information you wish to view.
Certain inquiries, such as basic graphical information about a parcel or its cadastral reference, can be made without the need for identification, provided they do not involve access to protected data.
To view protected information, download official certificates, or complete procedures such as declarations or requests for corrections, you must identify yourself using a digital certificate, an electronic ID, or the Cl@ve system.
The “My Cadastre” service allows each property owner to easily view all properties registered in their name, without needing to know their cadastral references in advance.
The Virtual Cadastre offers several ways to locate a specific property.
If you have the cadastral reference number, this is the fastest and most accurate way to directly access the complete property record for the corresponding property.
It is also possible to search for a property by entering its full mailing address—including the province, municipality, and street—when the cadastral reference is not available.
The map viewer allows you to locate a property by navigating directly on the map, which is especially useful for rural properties or parcels without a clear mailing address.
For certain technical purposes, the Virtual Cadastre also allows you to search by entering geographic coordinates or specific parcel data.
Knowing the cadastral reference is essential for most procedures related to a property.
The cadastral reference can be found on the property tax (IBI) bill, in the deed of sale for the home, or in the abstract issued by the Property Registry.
If you do not have any of these documents, you can obtain the reference through the Cadastre’s Online Portal by entering the property’s full address, which the system will automatically match to its corresponding reference.
The Virtual Cadastre allows you to obtain various types of official documents depending on the purpose of each inquiry.
This document provides a summary of the property’s physical, financial, and administrative data, along with its graphic representation, and can be downloaded for free.
The cadastral certificate is an official document with legal validity that certifies the data recorded in the Cadastre regarding a specific property; it is typically required for certain administrative procedures.
The Virtual Cadastre also allows users to download cartographic files in various formats, which are useful for real estate professionals, technical experts, and public agencies.
Downloaded documents include a Secure Verification Code that allows you to verify their authenticity and integrity through the Cadastre’s own Electronic Portal.
In addition to inquiries, the Virtual Cadastre allows users to complete various administrative procedures online.
You can file cadastral declarations to report physical, economic, or legal changes to a property, such as a home expansion or a change in use.
When an error is detected in a property’s cadastral data, you may request a correction by providing documentation that verifies the correct information.
In the event of discrepancies between the physical condition of the property and the cadastral data, there is a specific resolution procedure to update the relevant information.
In response to certain cadastral decisions, the owner may file appeals or submit objections within the legally established timeframes.
The Virtual Cadastre also allows for reporting changes in ownership resulting from a sale, inheritance, or gift, although this update does not replace the corresponding registration in the Property Registry.
Although both concepts originate from the Cadastre, they serve different tax purposes.
The cadastral value is primarily used to calculate the Real Property Tax, while the reference value serves as the minimum taxable base for the Property Transfer Tax and the Inheritance and Gift Tax, using the higher of the deed price and said reference value as the basis.
Both values can be looked up directly on the Land Registry’s online portal by entering the property’s cadastral reference number and selecting the corresponding tax year.
If the assigned reference value does not adequately reflect the property’s actual condition, it is possible to challenge it through the legally established channels, although the Constitutional Court has upheld the general validity of this system as an objective method of valuation.
It is not uncommon to find discrepancies between cadastral information and the actual condition of a property.
Renovations, additions, or subdivisions that have not been properly reported can lead to differences between a property’s actual area and the area recorded in the Cadastre.
Unformalized inheritances, old sales, or unreported gifts can cause the cadastral ownership records to be out of date compared to the property’s actual status.
Sometimes, the use recorded in the Cadastre—such as residential or commercial—does not match the property’s actual use, which can have tax implications.
Since they are independent agencies, it is common to find discrepancies between the data in the Cadastre and that in the Property Registry; therefore, it is advisable to cross-check both sources before any significant transaction.
Consulting the Virtual Cadastre before a real estate transaction provides key information for making informed decisions.
It allows you to verify that the property’s area, location, and characteristics match what is being negotiated in the transaction.
Comparing the cadastral information with the deed and the property abstract from the Registry helps identify potential discrepancies before signing any binding documents.
Cadastral information must always be supplemented with information from the Property Registry and, where applicable, with a technical report, since neither of these agencies alone provides a complete and definitive picture of the property.
Yes, basic access to cadastral data and the download of most documents are free through the Cadastral Service’s Online Portal.
Only the owner themselves, or third parties who can demonstrate a legitimate interest in accordance with current regulations, since this is protected cadastral information.
By accessing the Cadastre’s Online Portal with a digital certificate, electronic ID, or Cl@ve, and entering the cadastral reference number of the property in question.
Yes, through the declarations and correction requests available on the Electronic Cadastral Portal, by providing the necessary documentation to justify the change.
Regarding ownership and encumbrances, the Property Registry takes precedence, while the Cadastre is the primary reference for tax purposes and the physical description of the property.
The reference value is used as the minimum taxable base for the Property Transfer Tax and the Inheritance and Gift Tax, with the higher of the transaction price and the reference value being applied.
Cadastral information helps identify a property and understand some of its characteristics, but an investment decision also requires analyzing its legal status, location, prices, condition, and potential. Therefore, consulting public data is a starting point and does not replace a comprehensive evaluation of the investment opportunity.

Knowing what information is available, how to access it, and how it differs from the Property Registry helps avoid surprises and detect potential discrepancies early on. Always cross-check cadastral information with other documents, and, if in doubt, consult a specialized professional—this remains the safest way to approach any real estate transaction.
