Road freight in Spain is going fully digital, and this time there’s a hard deadline. From 5 October 2026, the DeCA Spain’s electronic transport document (Documento electrónico de Control Administrativo) becomes mandatory for domestic road freight operations. Other administrative control documents will also need to move to digital formats.
If your company operates in trucking, logistics, or freight forwarding in Spain, whether or not you’re based there, this change affects you directly. Here’s what’s new about DeCA Spain’s electronic transport document, what it means in practice, and how to make the transition without adding operational risk.

Why the DeCA Spain’s Electronic Transport Document Matters, Even If You’re Not a Spanish Company
Spain’s transport regulators aren’t just asking operators to swap paper for a PDF. The new rules, introduced under Law 9/2025 on Sustainable Mobility and detailed in a Resolution published on 5 June 2026, set specific technical requirements around the availability, integrity, and traceability of transport documentation.
For foreign carriers, freight forwarders, and logistics companies running routes through Spain, this means your existing document workflow, even if it’s already digital, may need adjustments to meet DeCA Spain’s electronic transport document requirements specifically.

What Exactly Is Changing
Two categories of national transport documentation move to a mandatory digital format:
- Freight transport: operators must hold a valid DeCA Spain’s electronic transport document for national road freight services.
- Passenger transport: national passenger services must use a digital version of the service route sheet (hoja de ruta).
What Is the DeCA?
The DeCA Spain’s electronic transport document is the digital equivalent of the administrative control document historically required for road freight transport in Spain. It’s the document that authorities check to verify a shipment is operating legally, and it forms the core of the country’s new digital transport document framework.
Requirements From 5 October 2026
Compliance isn’t just about having a PDF on a tablet. The regulation is specific about how DeCA Spain’s electronic transport document must be created and maintained:
- Native digital creation only. Scanned paper documents or converted files won’t be accepted; the document must be generated digitally from the start.
- File format and access. The PDF must not exceed 5MB and must include a unique URL and a QR code, so inspection authorities can check it instantly without logging in or navigating a website.
- Automatic timestamping. The system must automatically record the date and time the document was created, plus any later modifications.
- Retention period. Documents must be kept on file for at least one year.
Good News: You May Not Need a Separate Document
The regulation allows some flexibility around the DeCA Spain’s electronic transport document. If another electronic document already used in your operations, an eCMR (electronic consignment note), ADR documentation, waste transport records, or SANDACH documentation, contains all the information the transport rules require, it can serve as the DeCA. It simply needs to clearly identify the contracting loader and the actual carrier, among other mandatory data points.
In practice, this means companies already running digital transport management systems may be able to adapt their current documents rather than build something entirely new.
Why Traceability Is the Real Challenge
Digitisation brings speed, but it raises a harder question: how do you prove what information existed, and when?
The regulation requires systems to log the creation date and time of each DeCA Spain’s electronic transport document, along with any subsequent changes. If a new version of a document is created, the original must be preserved as well, so the full history of changes remains traceable.
That covers the internal record. But in disputes, audits, or inspections, companies often need something more: independent, verifiable evidence that specific data existed at a specific moment, evidence a court, auditor, or authority can trust without relying solely on your internal system logs.
That’s precisely the gap a Registered timestamp is built to close.
Adding a Layer of Trust: Electronic Timestamping
A timestamp cryptographically links a set of electronic data to a specific date and time, creating verifiable proof of when that information existed and allowing you to detect if it’s been altered afterwards.
Lleida.net’s Time Stamping service does exactly this for DeCA Spain’s electronic transport document and other transport records, giving you:
- Time-based proof that a document or dataset existed at a given moment.
- Data integrity checks to confirm whether sealed information has been modified since.
- Traceability across the lifecycle of a document or process.
- eIDAS grade trust, since a Registered timestamp carries reinforced legal guarantees under the EU’s eIDAS framework, relevant well beyond Spain’s borders.

Does It Need to Be Signed?
Not always. The Resolution clarifies that an electronic signature isn’t a general requirement for the administrative validity of DeCA Spain’s electronic transport document.
However, if the document also serves a contractual purpose and needs signatures, those signatures must meet at least the standard of an advanced electronic signature (AdES) under eIDAS, or a Registered electronic signature (QES), which is also valid.
Handling Contractual Signatures: Click & Sign
When a DeCA doubles as a contractual or commercial document requiring a signature, Lleida.net’s Click & Sign platform manages the full signing process digitally, securely, and with built-in traceability:
- Advanced and Registered signatures, AdES and QES options, matched to what each document needs.
- Fully online signing, send, review, and sign from any device, no printing or scanning.
- Tamper evidence, the signing process confirms the document hasn’t been altered afterwards.
- Electronic evidence, every signature is backed by evidence showing how, when, and by whom it was completed.
The Bigger Picture
The DeCA Spain electronic transport document mandate is another step in Spain’s push to digitise road transport, and it’s a preview of where documentation standards across the EU are heading. Going digital isn’t just about dropping paper; it’s about proving that information can be preserved, verified, and, when needed, traced back to an exact moment.
For companies operating in Spain, getting ahead of the 5 October 2026 deadline means reviewing your current document workflow now, checking whether your existing systems (eCMR, TMS platforms, etc.) already meet the requirements, and adding independent verification, such as timestamping and compliant e-signatures, wherever there is contractual exposure.
