IN Brief:
- Spain’s electronic DeCA requirement becomes mandatory from 5 October 2026 for affected public road freight operations.
- Documents must be created digitally before transport begins and stored as native PDF files with a unique URL and QR code.
- Drivers can present the DeCA electronically or carry a printed copy, but the record itself must originate and remain available digitally.
Spain’s Ministry of Transport and Sustainable Mobility now requires qualifying public road freight operations to use electronic administrative control documents, bringing the DeCA regime into mandatory use from 5 October.
The Documento Electrónico de Control Administrativo does not create a new underlying transport obligation. Operators already had to maintain administrative control documentation for affected services; the change requires that information to originate and be managed electronically after the statutory transition period.
Technical requirements were set out in a June resolution from Spain’s Directorate-General for Road and Rail Transport. A compliant DeCA must be created from structured data before the transport service begins and generated as a native digital PDF rather than a scan or photograph of a paper form.
The file must include a QR code linked to a unique web address from which the electronic document can be retrieved. The system must also preserve the date and time of creation and record subsequent changes where information is amended during the transport process.
Those requirements make the electronic record itself the authoritative document rather than a paper form that has subsequently been digitised. A scan does not meet the specification because the DeCA must originate through the electronic process described by the resolution.
Roadside inspection is built into the technical design. The unique link associated with the QR code must provide access to the PDF without requiring an inspector to enter credentials or navigate an additional authentication process before the record can be viewed.
Drivers may still present the document in different ways. An electronic copy can be shown on a device, while a printed version carrying the QR code is also permitted. The presence of paper in the cab therefore does not change the fact that the source record is digital.
Any amendment has to be made within the electronic process. Handwritten changes to a printed copy do not update the DeCA because the traceable record remains the digitally generated document and its recorded revisions.
The requirement affects the parties responsible for the transport documentation, including the contractual shipper and the effective carrier. Companies therefore need to determine how the necessary information enters the DeCA process before a vehicle starts the journey rather than relying on the driver to create compliance at the roadside.
Required information includes details such as the shipper, carrier, origin, destination, goods, weight and vehicle data according to the underlying Spanish administrative control rules. The electronic requirement changes how that information is generated, stored and presented rather than removing the existing data obligations.
The June resolution also permits several transport services to be grouped into one electronic document under defined conditions. Where that approach is used, individual consignments still need to remain identifiable within the combined record.
Other recognised transport documents can perform the same function where they contain the information required under Spanish law. This is relevant to freight already subject to specific documentation regimes, where duplicating the same transport data solely to satisfy DeCA requirements would add administration without improving traceability.
The resolution also recognises the EU electronic freight transport information framework. Where required information is managed and presented through the structure established by Regulation (EU) 2020/1056, operators can meet the Spanish requirement through that framework rather than maintaining a completely separate DeCA process.
That relationship is important for transport companies operating across several European markets because the wider eFTI programme is intended to reduce fragmentation in the way authorities accept electronic freight information.
Operators still need to distinguish between the Spanish requirement and the documentation applying to different international movements. DeCA relates to the affected services covered by national rules, so compliance should be integrated according to the journey being performed rather than attached indiscriminately to every truck movement.
Moving from paper-origin documents to electronic records creates new operational dependencies as well. Carriers and shippers need software capable of generating the required file, storing it, maintaining the unique link and making the QR code available to the driver.
A printed copy provides a practical roadside fallback, but it does not remove those digital requirements because inspectors must still be able to resolve the underlying electronic record. Document availability therefore becomes partly an information-system responsibility alongside the conventional transport task.
The required records must be retained for at least one year. Parties may use appropriate repositories for that retention provided the documentation remains accessible in accordance with their responsibilities.
The new regime brings administrative freight records closer to the digital systems already used for transport planning and execution. Operators that integrate DeCA generation with order, transport and vehicle data should require less duplicate entry than businesses treating it as a separate compliance process immediately before departure.
From 5 October, qualifying freight may still carry a printed representation in the vehicle, but the legal record behind it now begins as digital information and remains electronically accessible throughout its required retention period.
