Methodology and fact-checking: EU Data Act Guide

Each value carries the date on which it was checked, pending proposals and draft guidance are labelled as such, and an error is corrected against its source on every page that carries it. How the EU Data Act itself is structured is explained on the home page.

Which Primary Sources Every Statement Comes From

Four kinds of primary source are used, and where an official source is newer than a value on a page, the newer source wins and the page is corrected to it. Law firm, consultancy, vendor and news pages are never the source of a stated value, only leads to one:

Primary sources used on this site, as of 5 November 2026.

The Regulation as Published in the Official Journal

The legal text is Regulation (EU) 2023/2854 of 13 December 2023, CELEX 32023R2854, published in the Official Journal (OJ L, 2023/2854) on 22 December 2023. Every article reference is checked against that text on EUR-Lex and cited as the act numbers it, such as "Article 25(2)(a)". The act is a regulation, "binding in its entirety and directly applicable in all Member States" (Article 50); national laws designate authorities and set penalties, and the act is never described as transposed.

Corrigenda in the Official Journal are checked too. A corrigendum corrects a language version and is never reported as an amendment; no amendment of the act is in force as of 5 November 2026.

Commission Guidance and Its Non-Binding Status

Commission guidance explains how the Commission reads the Data Act, and the site cites it by version, question number and date, never as binding law. The Commission's FAQ library page (last updated 3 March 2026) lists version 1.4 of 22 January 2026 as the only version as of 5 November 2026. The FAQ states that it "should not be considered as representative of the European Commission's official position".

Where guidance and act differ, the act's wording is stated and the guidance is attributed to the Commission. The FAQ introduction misprints the act as "Regulation (EU) 2023/2584"; the site always writes Regulation (EU) 2023/2854. The non-binding guidance on vehicle data is cited as C(2025) 6119, with its Official Journal reference C/2025/5026.

National Gazettes and Competent Authorities

National values, such as which authority enforces the Data Act in a Member State and which fine ceilings apply, come only from the national gazette or the competent authority's own pages, and each carries its "as of" date. They are never copied from a Commission per-country listing. For the European Economic Area (EEA), incorporation of the act is read from EEA-Lex.

A national bill is written as a bill, with its chamber and stage. An authority's own reading of the law is attributed to that authority in the same sentence.

Legislative Registers for Pending Proposals

Proposals to change the Data Act are followed in the European Parliament's Legislative Observatory and the Council's register, and their stage is taken from there with the date it was read. The content of a proposal comes from the Commission proposal on EUR-Lex, and a stage is never inferred from press reports or commentary.

How Each Fact Is Checked before Publication

Before a page is published, each number, date and article reference on it is matched to the primary source it comes from, with the address of that source and the date it was read. A value not confirmed at a primary source is left out until it is, never softened with "reportedly" or "some sources say". A gap is stated only where the official source itself is silent: the Commission's Legal Helpdesk page gives no launch date, so the site gives none.

Canonical forms are fixed, so a value reads the same on every page:

• one act number, Regulation (EU) 2023/2854, in every citation;
• one date per event, with the article that sets it;
• one wording per period, cap or exemption, always with its condition.

How Dates and "As Of" Statuses Are Written

Every status that can change, such as a national act, a guidance document or a pending proposal, is written with the date on which it was last checked, in the form "as of 5 November 2026". Dates are written out in full, never as ambiguous numerals. An estimate or count keeps its own date and source; a page's check date is never attached to an older figure.

Entry into force on 11 January 2024 (Article 50, first paragraph) is kept apart from application since 12 September 2025 (Article 50, second paragraph) and from the staggered dates: Article 3(1), for example, covers connected products and related services "placed on the market after 12 September 2026" (Article 50, third paragraph). Every application date is listed in the Data Act timeline.

The forms used for each type of instrument are:

How Pending Proposals and Draft Guidance Are Labelled

A proposal or draft is always called proposed, pending or draft, with the body, the stage and the date, and is never written as if it were law. The Digital Omnibus, Commission proposal COM(2025) 837 of 19 November 2025 (procedure 2025/0360(COD)), is pending as of 5 November 2026: Coreper (the Member States' permanent representatives) agreed the Council's negotiating mandate on 21 October 2026, and the Legislative Observatory shows the European Parliament at "Awaiting committee decision". Nothing is written "as amended by" a pending proposal, and COM(2025) 837 would not amend Article 29 or Article 50, so those dates stand.

Draft guidance follows the same rule. The model contractual terms and cloud standard contractual clauses are a draft Recommendation approved by C(2025) 7750 of 19 November 2025, and the Article 9(5) compensation guidelines a draft published on 2 February 2026; neither is adopted as of 5 November 2026.

Corrections and How to Report an Error

If a value on a page is wrong or out of date, write to editorial@eudataact.net with the page address, the statement and, where possible, the primary source that shows the correct value. Each report is checked against the primary source; where the source confirms it, every page carrying the value is corrected, not only the page reported.

The corrected page shows its new check date. The site gives no legal advice and does not answer whether a named organisation is in scope.

What Triggers a Review of a Page

A page is reviewed whenever an event changes a value it states: an amendment of the Data Act, a new version of Commission guidance, a change in a national act or authority, or a step in a legislative procedure the page tracks. The triggers and their known dates are:

Each milestone is re-checked as it passes, with its condition: Chapter IV, for example, reaches contracts concluded on or before 12 September 2025 only if they are of indefinite duration or due to expire at least 10 years from 11 January 2024. A pending proposal is re-checked at each procedural step.

How This Page Relates to the Editorial Policy

This page explains how facts about the Data Act are sourced, checked, dated and corrected, while the rules that keep the site independent sit in a separate policy. How the site stays independent, how requests reach independent providers and why no provider can buy a place on eudataact.net are set out in the editorial policy.
