In recent years, Italy has accelerated the process of administrative digitalization. Today, citizens, professionals, and businesses use tools like SPID, CIE, PEC, digital signature, electronic invoicing, and compliant digital preservation to manage procedures, documents, and official communications. Understanding how they work and when they are truly needed is essential to avoid mistakes and work in compliance with regulations.

What is digital identity in Italy

Digital identity is the set of tools that allow you to identify yourself online to access services of the Public Administration and private entities. In Italy, the main identification tools are SPID and CIE.

SPID and CIE: tools to access online services

SPID (Public Digital Identity System) allows access to online services through personal credentials. It is currently the most used tool to enter PA portals. The CIE (Electronic Identity Card) is a physical document that can also be used as a digital identity via smartphone or NFC reader. For a detailed comparison between the two tools, you can read the dedicated guide: SPID or CIE: which to choose and when it really makes sense.

PEC: communications with legal value

PEC (Certified Electronic Mail) is not used for identification, but to send communications with legal value, equivalent to a registered letter with return receipt. It is mandatory for businesses and professionals registered with a professional body and represents an essential tool in official relations.

Digital signature: signing official documents

The digital signature allows you to sign electronic documents with full legal value. It differs from SPID and CIE because it is not used to access services but to sign contracts, acts, and official documents. It is a fundamental tool for professionals, businesses, and Public Administration.

Electronic invoicing: digital fiscal management

Electronic invoicing has revolutionized fiscal management in Italy. Invoices must be issued in XML format and transmitted via the Interchange System. It is not just digital submission: it entails specific archiving and management obligations.

Compliant digital preservation: legal document archiving

Saving a document as a PDF does not mean preserving it compliantly. Compliant digital preservation guarantees authenticity, integrity, and legal value over time. It is mandatory for electronic invoices and relevant fiscal documents. Read the guide: Compliant digital preservation: what it is, how it works, and when it is mandatory.

  • SPID and CIE are used for identification.
