Spains DeCA Mandate: What the New Digital Transport Rules Mean, and Where Ybil Fits In

Spain has just become the first country in the European Union to make digital transport documentation a legal requirement for road freight and the deadline is closer than most carriers realize.

From 5 October 2026, paper consignment notes will no longer satisfy a roadside inspection in Spain. What inspectors will ask for instead is the DeCA: the Documento electrónico de Control Administrativo, or electronic Administrative Control Document. If your fleet runs into or through Spain, this is no longer a future problem to plan around eventually, it's a compliance deadline with a fixed date and real penalties attached.

What is the DeCA?

The DeCA is an electronic document that must accredit every transport service performed: who contracted it, who carried it, the origin and destination, the goods being moved, and the vehicle and driver involved. It has to be accessible at any point during a traffic control, shown digitally, not printed out.

The legal basis is Ley 9/2025, de 3 de diciembre, de Movilidad Sostenible (the Sustainable Mobility Law), passed on 3 December 2025 and in force since 5 December 2025, as published in Spain's official gazette (BOE). The law set a ten-month transition period, which is why the hard deadline lands on 5 October 2026.

Spain also has a related but separate rule already in motion: the "carta de porte digital" (digital consignment note), introduced by Royal Decree-Law 14/2022 and its May 2023 ROTT amendment, which became fully mandatory for domestic B2B transport contracts over €150 in January 2026. It isn't the same instrument as the DeCA, but it points in the same direction Spain is phasing paper out of freight documentation from more than one angle at once, and both are now live.

The key dates

• 3–5 December 2025 - Ley 9/2025 passed and entered into force.
• January 2026 - the digital consignment note (carta de porte digital) reaches full mandatory status for qualifying domestic transport.
• 5 October 2026 - the DeCA becomes mandatory for roadside administrative control. Paper stops being valid.
• 9 July 2027 - the EU-wide eFTI Regulation (2020/1056) requires every Member State authority to accept electronic freight documents, extending the same principle across all 27 EU countries.

Spain is moving first, by nine months, on its own national timeline. The EU-wide requirement follows close behind. Two deadlines, same direction of travel.

What changes for carriers

The practical shift is what a driver hands over or rather, shows at a checkpoint. Instead of a folder of paper, it's a digital document accessed via a numeric code or QR code, satisfying the DeCA requirement on the spot. The responsibility for issuing the document sits with the carrier actually performing the transport, in practice the driver.

Non-compliance is not a minor technicality. Penalties under the current regime range from roughly €400 for errors or a missing document up to €18,000 for repeat serious infringements within 12 months, and vehicles can be held or immobilized at the roadside on top of any fine, meaning a documentation gap becomes an operational delay as well as a legal one.

How this connects to eFTI and eCMR

It helps to keep three related but distinct things straight, because the terminology gets tangled quickly:

• DeCA is Spain's national roadside control document, mandatory from October 2026.
• eFTI (Electronic Freight Transport Information) is the EU-wide regulation requiring all Member State authorities to accept electronic documents from July 2027, covering road, rail, inland waterway, and air.
• eCMR is the international electronic consignment note, legally equal to paper CMR since the 2008 Additional Protocol to the CMR Convention already valid today, independent of either deadline.

The strategic implication for carriers is straightforward: a platform built on the eCMR standard and eFTI-ready from the start can satisfy the Spanish DeCA requirement now and the EU-wide requirement later, without building a Spain-only fix that has to be replaced or extended in 2027 anyway.

Where Ybil fits in

This is exactly the gap Ybil's digiCMR was built to close. It's a digital e-waybill solution that's CMR Convention compliant today and eFTI-ready for 2027, letting a driver create, sign, and share a transport document digitally, with partners able to sign via a QR code or email link even if they don't have a Ybil account. Documents are generated in around three minutes instead of the 20-plus minutes a paper waybill typically takes, and the driver app works offline, which matters at exactly the roadside moments when connectivity is least reliable.

For carriers operating in or through Spain, that means the same document workflow that gets you DeCA-ready for October 2026 also gets you eFTI-ready for July 2027 one system addressing both deadlines instead of two.

This is also the logic behind Ybil's partnership with Mapon: Mapon covers fleet and driver visibility, while Ybil covers the document and compliance layer. Together, a carrier gets full readiness vehicle tracking and compliant paperwork from one combined setup rather than stitching together separate tools under deadline pressure.

What to do now

Spain's ten-month transition window is most of the way through. Companies that wait until September 2026 to start testing a digital workflow will be doing it under time pressure, with drivers untrained and no room for a rocky rollout. The companies handling this comfortably are the ones piloting now, training drivers before the deadline, and picking a system that also covers the EU-wide requirement that follows in 2027 rather than solving Spain twice.
