Online

You can identify the limits of your property online by logging in with your Citizen Card (requires a card reader and plugin) or with your Digital Mobile Key (CMD) and respective PIN codes.

BUPi Desks

If you need the support of an authorised technician or do not have electronic authentication, you can identify your properties at a BUPi Desk. Check the list of BUPi Desks in the municipality where your property is located.

To identify properties

Identification of your properties through BUPi — whether online or at a BUPi Desk with a qualified technician — is always free of charge.

To register property ownership

For properties that have never been registered at a Land Registry Office, or whose registration is not up to date, the registration is also free.

Both identification and registration are free until 31 December 2025.

Online

To identify the location and limits of your property online, you must log in using your Citizen Card and PIN codes. Alternatively, you can use your Digital Mobile Key (CMD), with access to the associated phone.

You must also have your Tax Authority Land Certificate, which contains the matrix numbers of the properties you wish to georeference.

If you already have a GPS file with your property's coordinates, you can upload it to the BUPi platform. If not, you can identify your property directly on the map.

BUPi Desk

When visiting a BUPi Desk, you should bring your Citizen Card and the Tax Authority Land Certificate showing the matrix numbers of the properties to georeference. Alternatively, you can provide the matrix number and your NIF so that the authorised technician can retrieve the certificate via the Tax Portal.

You should be able to locate your property on the map and, if possible, bring a GPS survey of the property’s limits. If you're unable to identify your property, our technicians at the BUPi Desk can assist you.
