Official Journal electronic signature verification


CheckLex enables you to verify the electronic signature and authentic character of the electronic edition of the Official Journal of the European Union. If verification succeeds, it gives you a guarantee that the electronic edition is authentic and it has not been changed since the date of its signature.

Effective 1 July 2013, the electronic edition of the OJ (e-OJ) is authentic and produces legal effects, pursuant to Regulation 216/2013 on electronic publication of the Official Journal.

The e-OJ bears an advanced electronic signature to ensure its authenticity, integrity and inalterability, in accordance with Directive 1999/93/EC.

Paper versions will no longer have any legal value, except for cases where – due to an unforeseen and exceptional disruption of the Publications Office's IT systems – the e-OJ cannot be published.
