DNI

The *Documento Nacional de Identidad* (DNI) is the national identity document of Spain. Recent news highlights its increasing relevance due to the introduction of a digital version accessible via mobile devices. This digital DNI, launching imminently, allows citizens to identify themselves to various entities using a QR code. This includes activities like voting, signing documents, opening bank accounts, hotel registration, and package collection. While offering convenience, the digital DNI currently has limitations, as it cannot be used in all situations. Furthermore, the DNI is linked to important processes like tax filing, as the address registered on the DNI (domicilio fiscal) is used by the tax agency for communication and notifications. Maintaining an accurate address on the DNI is crucial to avoid errors or penalties when filing taxes.
