eIDAS in One Sentence
eIDAS (Electronic IDentification, Authentication and trust Services) is European Regulation No. 910/2014 which unifies the legal framework for electronic signatures, digital identity and trust services in the 27 Member States.
It entered into force on 1 July 2016 with direct legal effect in each Member State.
Why eIDAS Was Created
Before 2016, each country had its own law. A signature issued in France was not automatically recognised in Germany.
eIDAS solves three problems:
- Legal fragmentation: a single framework for 27 countries
- Mutual recognition: a signature valid everywhere
- Harmonised levels: three standardised levels (SES, AES, QES)
The Three Signature Levels
- Simple signature (SES): any electronic consent
- Advanced signature (AES): unique identification + strong authentication
- Qualified signature (QES): AES + qualified certificate + secure device
For details, see simple, advanced, qualified.
Trust Service Providers (TSP/QTSP)
eIDAS creates the status of trust service provider (TSP), which can be qualified (QTSP) if it is audited and registered on the trust list of a Member State. In France, the ANSSI maintains this list (Docaposte Certigna, Universign, CertEurope…).
Mutual Recognition
A signature issued by a French QTSP is automatically recognised throughout the EU. This principle also applies to digital identities: FranceConnect+ will be interoperable with identity wallets in other States under eIDAS 2.0.
Principle of Non-Discrimination (Article 25)
Even a simple signature is admissible. The judge assesses the reliability of the process, but the digital format alone is not grounds for rejection.
eIDAS 2.0: What Changes
Regulation (EU) 2024/1183 modernises eIDAS with the European Digital Identity Wallet (EUDIW). By the end of 2026, each State must provide a mobile application to store identity credentials and sign with a QES.
What It Changes for Your Business
- Sign with EU counterparties without negotiating the framework
- Choose an eIDAS-compliant provider
- Prepare for EUDIW (2026-2027)
- Adapt the level to the issue at hand

FAQ
Is eIDAS mandatory?
Strongly recommended for any signature with cross-border EU legal value.
Difference between eIDAS and GDPR?
eIDAS governs signatures and identities. GDPR governs data protection. Complementary.
Can I sign with a non-EU provider?
Legally yes, but cross-border recognition is limited.
Does ANSSI certify platforms?
ANSSI qualifies QTSPs (for QES). For SES/AES, it is the provider's eIDAS compliance.
How do I know if a document is signed in QES?
In Adobe Reader: signature properties → level and certificate. See verify a signed document.

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