From 5 October 2026, Spain will require a digital Documento de Control Administrativo (DCA) for commercial road freight transport. What was meant to have an effect for domestic transports and cabotage control only, will, in practice, also be relevant to much of the transit traffic passing through the country. Companies should take action now.
The Documento de Control Administrativo (DCA) is an administrative control instrument under Spanish transport law that, until now, was mandatory to be used paper form. However, a change in the law will make the digital version mandatory from October 2026. It is neither a ‘Spanish eCMR’ nor a consignment note in the contractual sense. It regulates neither liability nor the condition of the goods, but serves as an official control document. Nor should it be confused with the upcoming European eFTI regulation, which aims at structured data exchange between businesses and authorities. From October 2026, a paper copy of the DCA will no longer suffice.
“The DCA is not about a new digital data world, but about the digital replication of a paper-based process”, explains Dr. David Saive, Legal Product Owner at the Open Logistics Foundation. “Anyone who cannot provide the document digitally immediately will face an operational problem in future”.
Access on demand: QR code or reference number
A deciding factor is how the DCA is made available during an inspection. The Spanish approach is ‘view-by-request’: no structured interfaces with the authorities, but rather a document-based approach where an unstructured document must be provided on request. There are two ways to do this. In the first, a numerical reference is issued during the inspection, and the company makes a PDF version of the document available via the authorities’ portal. In the second method, the company registers a central server path in advance, and the driver then presents a QR code that leads directly to it. The key point is that access to the document must work immediately during an inspection, whether via a smartphone, a driver’s tablet, or a back office.
Covering the DCA with the eCMR
As the DCA is largely similar with the CMR consignment note in terms of content, a correctly implemented eCMR can functionally replace the DCA, provided that the requirements of the Resolución of 22 May 2023 – the Spanish implementing regulation for the digital DCA – are met.
The technical requirements depend on the method chosen. The following applies to both methods: the document must be in PDF/A format and accessible online. Those using the QR code method require not only the QR code on the document but also a domain registered in advance with the authorities. In addition, there are mandatory fields that many eCMR data models do not yet cover: registration numbers of the tractor unit and trailer, as well as any special transport permits where applicable.
Anyone who incorporates these requirements into the data model can use the eCMR functionally as a DCA, thereby avoiding parallel systems. “Digitalisation is not about recreating paper documents on a screen. It is about designing systems that replace multiple paper-based processes with one shared digital infrastructure.”, says Dr Saive. Building a separate system for every mandatory document does not solve a problem; it simply creates the next one. In the long term, this becomes expensive, error-prone and difficult to scale. Therefore, the changes in Spain should not be a reason to develop country-specific silo solutions, but rather to set up the eCMR so that national requirements can be seamlessly integrated. As a neutral and open source solution, the OLF-eCMR is designed precisely for this purpose.
Prepare now for what matters during inspections
For many foreign companies, the real hurdle lies not in creating the digital DCA but in accessing the Spanish platform. Foreign documentation is not always sufficient. The recommendation is therefore clear: check now whether your own processes cover the inspection requirement. Where is the document? Who can provide it immediately in an emergency? How can the driver quickly gain the right access? And who will handle the formalities with the Spanish authorities? In the end, only one thing matters: the carrier must be able to produce the necessary documentation during an inspection.
Interoperability paves the way for DCA and eFTI
Some view the Spanish DCA as a precursor to the upcoming eFTI regulation. However, the two requirements differ fundamentally. eFTI aims to facilitate structured data exchange between businesses and public authorities, whereas the DCA remains a document-based proof of inspection. For businesses, both systems may become relevant in parallel. This is precisely why it is worth choosing not the quickest solution, but the most adaptable one. Open source approaches such as the Open Logistics Foundation’s eCMR are designed for this purpose: open, interoperable, and extensible, so that every new regulatory requirement does not necessitate a new system.
