The eCoC mandate takes effect 5 July. Machine-readable vehicle data, verified at the source, is now the legal baseline for registration.
The signal
From today, 5 July 2026, every new vehicle approved in the EU must have its Certificate of Conformity available as a structured electronic record (eCoC), accessible to public authorities through secure exchange systems. The eCoC is not a scanned PDF of the old document: it is a digitally signed XML record carrying the vehicle's specifications and type-approval references, generated by the manufacturer and distributed to registration authorities through the EUCARIS exchange. The change sits under Regulation (EU) 2018/858 and its implementing rules 2021/133 and 2024/1061 (eIDEasy). Paper gets a short runway: manufacturers may keep issuing paper certificates or eCoC printouts until 29 November 2026 at the latest, while infrastructure gets tested (COC-Express). The direction is fixed either way.
It does not arrive alone. From 1 July, the second-generation smart tachograph (G2V2) with a standardised ITS interface became mandatory on vans between 2.5 and 3.5 tonnes in international transport, feeding structured trip and distance data straight into fleet systems (Optivo). Same week, same direction: the paperwork around a vehicle is turning into signed, structured, exchangeable data.
Why it matters
For decades, a vehicle's official identity lived on paper and in disconnected national databases. A certificate of conformity was a document you filed, not a record you could query. That is the gap this week starts to close. When the founding document of a car's legal life is born as signed XML, the whole picture downstream gets easier to verify and harder to fake.
This is the same current running through the bigger regulations already in motion. The EU Data Act becomes enforceable in September 2026, requiring connected-vehicle manufacturers to give owners and their chosen third parties direct access to the data their cars generate (grapeup). Delegated Regulation (EU) 2026/699, published on 3 June 2026, forces manufacturers to open diagnostic and repair information to independent workshops on equal terms (CambiosLegales). Read together, the message to the market is plain: vehicle data is moving out of private silos and into structured, accessible formats, by law, on a schedule.
The reason regulators keep pushing here is the cost of the gap. Studies for the European Parliament put odometer tampering at 5 to 12 percent of cars sold within a country, and 30 to 50 percent of cars sold across borders, with total damage estimated between €5.6 and €9.6 billion across the EU (European Parliament study). Incomplete and incorrect information is not a rounding error in this market. It is a structural tax on trust.
What it means for dealers, marketplaces, insurers, and finance providers
Start with the Nordic used-car floor. Roughly 643,000 used cars changed hands in Finland last year, up 4.1 percent, while new registrations stayed weak (MTV Uutiset). More of the market's value is riding on used vehicles, and used vehicles are exactly where the information is thinnest. Finland's Competition and Consumer Authority reports over 10,000 vehicle-related complaints a year, with nearly two-thirds tied to used-car sales, and vehicles now driving close to a third of all consumer contacts (MTV Uutiset).
The eCoC shift does not fix that on its own. A signed certificate at registration is one clean data point, not a lifecycle. But it changes the shape of what is possible. When the anchor record is structured and verified from day one, everything you attach to it later (inspection results, ownership changes, service events, mileage readings) has something trustworthy to attach to. The registration record stops being a dead end and starts being a spine.
The practical near-term effect is quieter than a headline. Systems that price, insure, or finance a car will increasingly expect to read vehicle facts as data, not interpret them off a scan. A dealer platform that already ingests structured type-approval data will onboard cross-border stock faster. An insurer that can read a verified specification at quote time prices with less guesswork. The teams that treat this week as a compliance checkbox will meet the same requirements as the teams that treat it as a data pipeline. Only one of them gets faster in the process.
The data view
This is the layer Good2Know was built for. The regulations arriving this month and this autumn all produce the same raw material: structured, verified vehicle data from official sources. That data still lands in fragments, one authority, one manufacturer, one registry at a time, each with its own format and its own gaps. Turning fragments into a single clear picture a system can act on is the work.
Good2Know sits underneath that as infrastructure, not as another report. We aggregate fragmented lifecycle data from insurers, inspection stations, manufacturers, authorities, and marketplaces, then structure and verify it into one view delivered through an API inside the workflows that already exist. The eCoC is a good example of the pattern: a new signed data source appears, and the value is not in displaying it, it is in interpreting it alongside everything else about the vehicle so a decision gets faster and cleaner. When the EU makes structured vehicle data the default, the useful question stops being "can I get the data" and becomes "can I make sense of all of it at once."
What we're watching next
- July to November: how many manufacturers actually switch to eCoC-only ahead of the 29 November paper cutoff, and whether EUCARIS exchange friction slows cross-border registration in practice.
- September 2026: EU Data Act enforcement, and the first real tests of how manufacturers deliver owner and third-party access to connected-vehicle data.
- Independent access: how quickly Delegated Regulation (EU) 2026/699 changes what workshops and third parties can pull, and how clean that diagnostic data is once it flows.
- Nordic consumer pressure: whether Finland's KKV moves from investigation to enforcement on used-car information standards, and whether Sweden and Norway follow.
- Cross-border stock: whether structured certificates measurably cut the friction (and the fraud) in cross-border used-car flows, where tampering rates run highest.
