In 2026, the Slovenian advertising landscape underwent an important update. The fifth edition of the Slovenian Advertising Code (SAC), which came into force on March 19, 2026, represents a comprehensive revision of the fundamental self-regulatory document for advertising in Slovenia. It responds to the rapidly evolving digital environment, global trends, and new challenges faced by advertisers.
What is the Slovenian Advertising Code?
The Slovenian Advertising Code (SAC) is the core act of self-regulation in the field of advertising in Slovenia. It represents a set of principles and rules that advertisers must follow when preparing advertisements and other forms of marketing communication.
Its main purpose is to ensure lawful, ethical, and responsible advertising, as well as to protect consumer interests and the reputation of the profession.
Compliance with the Code is assessed by the Advertising Arbitration Board, which operates as an independent self-regulatory supervisory body.
Upgrade of Fundamental Principles
Although the new edition retains the key principles of the previous version - legality, decency, honesty, truthfulness, substantiation, recognizability, social responsibility, and privacy protection - it significantly upgrades them.
The Code introduces new concepts such as advertising using artificial intelligence and so-called ambush marketing, and provides more precise definitions and stricter rules.
In doing so, it not only follows the development of practice but also actively shapes standards for responsible and ethical advertising in the modern environment.
Key Innovations of the Fifth Edition
The revised Code introduces several important changes reflecting current challenges:
• Alignment with EU law: clearer scope of application and mandatory compliance with European legislation
• Stricter standards of decency and fairness: restrictions on offensive, degrading, or shocking content
• Greater transparency: fine print must not contradict the main message
• Digital and influencer advertising: mandatory clear labeling of paid content and disclosure of partnerships
• Environmental claims: strict rules against misleading “greenwashing”
• Protection of children: lower age threshold (under 15) and stricter rules for advertising unhealthy food
• Health and nutrition claims: requirement of scientific substantiation and prohibition of misleading promises
• Ban on ambush marketing: prevention of unauthorized association with events or sponsorships
Artificial Intelligence in Advertising
One of the most important innovations is the introduction of a specific provision on advertising created using artificial intelligence. It sets out clear rules:
• artificial intelligence must not be used for manipulation or deception,
• all claims must be verifiable,
• its use must comply with personal data protection rules (GDPR),
• bias and discrimination must be prevented,
• advertisements created using artificial intelligence must be appropriately labeled.
This part of the Code clearly demonstrates that regulation recognizes the impact of technology and strives to ensure its responsible use.
Greater Protection of Consumers and the Reputation of the Profession
Although the fundamental principles remain similar, the new edition of the SAC significantly strengthens consumer protection. At the same time, it contributes to greater trust in the advertising industry and enhances its reputation.
It represents an important step toward modern, transparent, and responsible advertising aligned with both international standards and societal expectations.
