This is data that appears in several documents, such as purchase agreements (as it is a fundamental piece of information for selling and buying an apartment), in the IBI receipt (Property Tax charged by the voluntary collection service of any municipality in Spain, which taxes the ownership of real estate) or in the habitability certificates of the properties.
How can we know that the cadastral reference of our property is correct? Where should I request it?
On the other hand, it is always a good idea to check that the digitization of our cadastral reference is correct by visiting the website of the Electronic Cadastre Office online. This check is not trivial; sometimes, this information may be incorrectly transcribed in the deed or the certificate of occupancy because it is very old data that has passed through too many hands to the present day.
You can access it directly by providing the following documentation:

- Electronic identification certificate or electronic DNI
- Cl@ve Pin - Permanent Cl@ve

What is it for?
The calculation of the IBI receipt and other taxes, fees, and special contributions charged by our municipality derives from the cadastral value for the calculation of the taxable base of the receipt, so it is more than advisable that this information be as accurate as possible.
Where can I see my cadastral reference?
In this way, and with a simple copy of the deed of our house, a paid IBI receipt from the previous year, or the certificate of occupancy of our home, we can access the Electronic Cadastre Office and validate, by ourselves, that the 20 digits that make up our cadastral reference are correct and we do not have to carry out a review due to data discrepancy in the Cadastre of our municipality.
In general, it is more likely that the data is wrong from the Municipal Electronic Cadastre Office than from a notary; however, the validation of this cadastral data is important to avoid corrections in the cadastre that result in the incorrect calculation of our taxes or in an exorbitant sale price that does not correspond to reality.

When processing documents with the Public Administration, it is possible that the Cadastre itself determines a discrepancy in cadastral data between those we provide and those they have.
In these cases, we will have no alternative but to present our own documentation to resolve the error as quickly as possible, trying to clarify that our cadastral data is correct.
For this, we will use our own property deed, certificate of occupancy, or Property Tax in a parallel file that definitively substantiates the accuracy of our municipal cadastral data.
Another common case is not finding the property through the address data in the Cadastre Office of your municipality. This may be normal and common since some homes may have one administrative address and another for correspondence; especially if the information has been provided to us by the owner of the house via telephone or email.
Common errors when requesting the cadastral reference in the Electronic Office
When entering the numbering of our cadastral reference in the Office, we must check carefully that we are not mistaken when interpreting them correctly. For example:
- Do not confuse an O with a zero.
- The last 4 digits of the cadastral reference correspond to the housing or local unit; the previous 16 define the entire building where it is located.
- The reference is 20 digits. Some old IBI receipts or those with a small receipt format may not reflect all of them correctly, so it will be necessary to ask at the Town Hall.
You can request it by telephone
Through a phone call to the number 902 37 36 35 or 91 387 45 50 at the General Directorate of the Cadastre, you can request the cadastral reference of a home. They will require the exact address you want to verify and the data of the owner and proprietor of the property.
Town Hall and Provincial Councils
The Town Halls and Provincial Councils have a cadastral information office; however, they will not always assist you by telephone. If you want to get the cadastral reference quickly, we recommend that you go to these offices.
Infractions for lack of requirements
In the event that you want the cadastral reference to sell a home and you do not provide the necessary documentation within the deadlines established by the Public Administration, you will be incurring an infraction that may range between €60 and €6,000. From Euroval, we recommend that you have all the documentation before carrying out this action in order to avoid problems.
