European repository for political advertisements
The European repository for political advertisements is a centralized, publicly accessible online database where providers of political advertising services must store information about political ads disseminated in the European Union. This repository enables public scrutiny, research, and oversight of political advertising practices across all Member States, ensuring transparency in democratic processes.
Legal Basis
"The Commission shall establish and operate a publicly accessible, machine-readable repository of political advertisements ('European repository'). [...] Providers of political advertising publishing services shall transmit the information set out in paragraph 2 of this Article to the European repository within 5 days of the first publication or dissemination of a political advertisement, and update that information without undue delay when necessary."
— Article 10(1), Regulation (EU) 2024/900
Why It Matters
The European repository creates accountability and enables citizens, journalists, researchers, and civil society to monitor political advertising across the EU. By centralizing transparency notices in one searchable database, it helps detect potential violations, foreign interference, and patterns of manipulation that might otherwise remain hidden in fragmented national systems.
Providers of political advertising publishing services have a direct legal obligation to submit information to the repository within five days of first publishing any political advertisement. This applies regardless of whether the ad appears online, on television, in print, or through any other medium. Failure to submit or maintain accurate information can result in significant penalties.
The repository serves as a critical tool for protecting democratic integrity. It allows researchers to analyze spending patterns, targeting practices, and the sources of political messaging. Electoral authorities can use it to verify compliance with national campaign finance rules. Citizens can see who is trying to influence their vote, with what messages, and how much money is being spent.

European repository vs. Transparency notices
While transparency notices are the labels and information displayed with each individual political advertisement, the European repository is the central database where all this information is collected and stored. Think of transparency notices as the price tag on a product, while the repository is the accounting ledger that records all transactions. Publishers must display transparency notices on ads themselves and also submit the same information to the repository for permanent public record.
