eIDAS in one sentence
eIDAS (Electronic IDentification, Authentication and trust Services) is European regulation No 910/2014, which unifies the legal framework for electronic signature, digital identity and trust services across the 27 Member States.
It came into effect on 1 July 2016, with direct legal force in every Member State.
Why eIDAS was created
Before 2016, each country had its own law. A signature issued in France was not automatically recognized in Germany.
eIDAS solves three problems:
- Legal fragmentation: a single framework for 27 countries
- Mutual recognition: a signature valid everywhere
- Harmonized levels: three standardized levels (SES, AES, QES)
The three signature levels
- Simple electronic signature (SES): any form of electronic consent
- Advanced electronic signature (AES): unambiguous identification + strong authentication
- Qualified electronic signature (QES): AES + qualified certificate + secure device

Trust service providers (TSP/QTSP)
eIDAS creates the status of trust service provider (TSP), which can be qualified (QTSP) if it is audited and listed on a Member State's trusted list. In France, ANSSI maintains this list (Docaposte Certigna, Universign, CertEurope…).
Mutual recognition
A signature issued by a French QTSP is automatically recognized throughout the EU. This principle also applies to digital identities: FranceConnect+ will be interoperable with other Member States' identity wallets under eIDAS 2.0.
Principle of non-discrimination (Article 25)
"An electronic signature shall not be denied legal effect and admissibility as evidence in legal proceedings solely on the grounds that it is in electronic form."
Even a simple electronic signature is admissible. The judge assesses the reliability of the process, but the electronic format alone is not grounds for rejection.
eIDAS 2.0: what's changing
Regulation (EU) 2024/1183 modernizes eIDAS with the European Digital Identity Wallet (EUDIW). By the end of 2026, every Member State will have to offer a mobile app for storing identity attestations and signing with a QES.
What this means for your business
- Sign with EU counterparties without negotiating the framework
- Choose an eIDAS-compliant provider
- Prepare for EUDIW (2026-2027)
- Match the signature level to the stakes

FAQ
Is eIDAS mandatory?
Strongly recommended for any signature with cross-border legal value within the EU.
What's the difference between eIDAS and GDPR?
eIDAS governs signatures and identities. GDPR governs data protection. They are complementary.
Can I sign with a non-EU provider?
Legally, yes, but cross-border recognition is more limited.
Does ANSSI certify platforms?
ANSSI qualifies QTSPs (for QES). For SES/AES, it is the provider's eIDAS compliance that matters.
How can I tell if a document is signed with a QES?
In Adobe Reader: signature properties → level and certificate. See verifying a signed document.

eIDAS is the European foundation that makes electronic signatures legally reliable, cross-border and standardized.
