Regulation
Does the DeCA need an electronic signature?
Updated on September 29, 2026 · 4 min read
Short answer
- No. None of the regulations applicable to the DeCA require an electronic signature.
- What the Resolución de 5 de junio de 2026 does require is logging the date and time the file was created and any modifications.
- The eIDAS advanced signature only comes into play if the document must also serve as a consignment note or eCMR.
- If someone offers an electronic signature as a legal DeCA requirement, they're selling you something else.
Short answer: no. Neither Orden FOM/2861/2012, which sets the control document's content, nor the Resolución de 5 de junio de 2026, which sets the characteristics of the electronic file and the application that generates it, require an electronic signature for the DeCA to be valid.
What the regulation requires instead
What the Resolution does ask for is traceability, which is a similar idea but much cheaper to implement: the software application must log the date and time the electronic file was created, and also the date and time if there's a modification.
That log serves the purpose you'd expect from a signature in this context — knowing when it was issued and whether it was touched afterwards — without needing certificates or qualified providers.
Why the time log matters so much
Because it's exactly the proof article 7.1 of Orden FOM/2861/2012 refers to. When the document isn't carried on board the vehicle, both the contracting loader and the actual carrier are liable, unless the loader proves the document was issued. The creation stamp logged by the application is that proof.
When a signature is actually needed
When you want the same document to serve for more than just administrative control. The advanced electronic signature under the eIDAS Regulation becomes relevant if the document has to function as a consignment note or as an eCMR — that is, if it will support a commercial claim between the parties about the transport contract or the condition of the goods.
That's a different product, with different requirements and a cost that's nothing alike. It's also why eCMR solutions start at figures of several thousand euros a year: they're solving an evidentiary problem, not an administrative one.
So what do I actually need?
- A natively generated, not scanned, PDF under 5 MB.
- A QR code with the document's unique web address.
- A directly accessible HTTPS URL with no authentication.
- A log of the creation date/time and of any modification.
- The eight data items of article 6.
- Retention of at least one year.

That the application log the date and time the electronic file was created and, if applicable, the date and time it was modified.
When do I actually need an advanced electronic signature?
When the document must also serve as a consignment note or eCMR with evidentiary value in a commercial claim. It isn't necessary for administrative control.
Do I need a digital certificate to issue the DeCA?
No. No certificate or qualified trust service provider is required to issue the administrative control document.
