These policies are published on Universign website. Universign is audited every year on the basis of these policies by a conformity assessment body.

Accepting the certificate

When Universign issues a Certificate for the User, it informs him/her by e-mail that his/her Certificate is available.

The User may retrieve their Certificate from the Universign Platform.

The User must  inform Universign of any inaccuracy or error in the Certificate within 48 hours. After this period, the Certificate is deemed to be accepted.

Verifying the Certificat

Universign will provide a consultation service available on the Universign website to enable the validity check of the Certificates it has issued, for level 2 and 3 Electronic Signatures.

This service is available 24/7.

The information made available to the Certificate User by Universign enables the User to verify and validate, prior to its use, the status of a certificate and the corresponding certificate chain, specifically to verify the signatures in the certificate chain and the signatures guaranteeing the origin and integrity of the CRL.

In the event that the CA ceases its activities, Universign shall take the necessary steps to transfer its obligations to a competent body for the time periods it has committed to with regard to the Users, in accordance with its Certification Policies.


When the User uses a Qualified Certificate, Universign guarantees the User:

  • the accuracy of all the information contained in the Qualified Certificate on the date when it was delivered and the presence, in this Certificate, of all the prescribed information for a Qualified Certificate;
  • that at the time of the issuance Certificate, the Signer identified in the Qualified Certificate held the signature creation data;
  • that the signature creation data and the signature validation data can be used in a supplementary way.


These Specific Terms of Use (STU) are specifics to Universign Electronic Signature Service.

They supplement the Terms of Use which apply to Universign Services. In the case of a contradiction between the ToU and the STU, the provisions of the STU shall prevail.


The Electronic Signature Service provides the User with a solution for creating an Electronic Signature and for the Signer to attach their Electronic Signature to all types of Documents.

The Signature Service is directly accessible via the Universign Platform and on Universign website, Universign apps or through Universign API integrated with the User’s software. Universign Signature Service enables three categories of Electronic Signatures to be implemented, classified in accordance with the regulatory and normative requirements to which they comply.


By using the level 1 Signature, the User is solely responsible for the Signer identification using its own organizational and technical processes. Indirect authentication of a declared Signer is carried out by Universign.

In using this level of Signature, Universign cannot guarantee the identity of the Signer, as the only elements of identification provided are those sent by the User. User will ensure, through their own methods and under their own responsibility, the identity of the Signer.

Universign bears no responsibility for the identification of the Signer except for that of using the identification data provided by the User and of retaining the data relating to this process.


In implementing the level 2 Electronic Signature, the Signer identification is carried out remotely by Universign via a scanned copy of the Signer’s ID sent to Universign. Authentication of the Signer is carried out by Universign.

In using this level of Signature, even if Universign proceeds with verifying an  identification document (ID card, passport, …) remotely, it cannot fully guarantee the identity of the Signer. Consequently, it is incumbent upon the Users to ensure, through their own methods and under their own responsibility, the identity of the Signer.

Universign bears no responsibility for the identity of the Signer except for the responsibility of verifying the validity of the identification document against the copy sent to it and of retaining the technical data related to this process.

The level 2 Electronic Signature is implemented using Certificates in accordance with the requirements of the standard ETSI EN 319 411-1.


In implementing the level 3 Electronic Signature, the Signer Identification is carried out, in their presence, by a Registration Operator and then remotely by Universign via a scanned copy of the Signer’s identification document which has been sent to it.

The Registration Operator is responsible for carrying out a physical face-to-face identification of the Signer.

The level 3 Electronic Signature is implemented using Qualified Certificates in accordance with the requirements of the standard ETSI EN 319 411-2.

Electronic storage

Universign stores the Documents signed using the Electronic Signature Service in such a way as to preserve their integrity.

The storage enables the signed Documents to be consulted online, as well as their retention, restitution and/or their destruction.

Universign reserves the right to deposit the stored Documents with specialist third-party companies.

The User’s Documents are archived starting from the date of their deposit and up until the User’s account is closed.

Outside of the Service, it is the responsibility of the User to make all provisions to ensure the preservation of the Document.


Universign stores the signed Documents in their original format by taking the security measures required to ensure their integrity and their confidentiality.

Garantee limits

Except for cases where verifying the identity of the Signer is included as part of the Service offered, Universign cannot, in any case, be held liable in this respect. It is the User’s responsibility to ensure this through their own means.

As part of using the Electronic Signature Services any delegation of signature is prohibited.

Data retention

Pursuant to the CP, data in the event logs are retained for the period required for the provision of proof in the case of a dispute about the validity of a Document signed using the Service and in the event of any judicial or administrative requirement.


These STU supplement the Terms of Use and govern the conditions of use for Universign Time-stamping Service. In the case of a contradiction between the ToU and the STU, the provisions of the STU shall prevail.

Universign timestamping service

Universign Timestamping Service allows the timestamping of all types of Documents via Universign Platform or through Universign API integrated into the User’s software. It includes the generation and the delivery of a Token.

Timestamping service user’s obligation

Universign recommends that the User of the Time-stamping Service verifies and validates the Certificate used to deliver the Token at the time of the time-stamping request.


Universign guarantees that the Tokens produced by its Time-stamping Service are accurate within one (1) second with respect to universal time.

Universign retains the audit files from the Time-Stamping Token creation for a period of six (6) years after its end-of-life.

Universign guarantees that in case of an event affecting the Time-Stamping Service security, and which could have an effect on tokens issued by Universign, the appropriate information will be made available to Users through the Universign website.

Universign guarantees access to the information required by Users for verifying the Electronic Signature of Certificates used for Time-stamping Documents.
