What is the OJS eSender certification?
The OJS eSender certification is the official authorisation procedure of the European Commission by which software providers and procurement platforms acquire the right to transmit procurement notices electronically on behalf of public contracting authorities to TED (Tenders Electronic Daily) – the Supplement to the Official Journal of the EU (OJS, Official Journal Supplement). Only certified eSenders may transmit notices directly via the TED API to the Publications Office; public contracting authorities that do not have their own eSender certification depend on the services of certified platforms or the manual TED eNotices portal.
With the introduction of the eForms standard by Implementing Regulation (EU) 2019/1780 – binding since October 2023 for EU above-threshold awards – the technical requirements for eSenders were fundamentally modernised. eForms replace the previous standard forms (SF) with a machine-readable, structured XML-based data format. Certified eSenders must design their systems in an eForms-compatible manner and update them regularly when the EU Commission publishes new versions of the eForms specifications.
Significance in the award procedure
The OJS eSender certification is a central quality feature for procurement platforms: it proves that the platform is technically capable of transmitting EU-compliant notices to TED on time and in full, and relieves public contracting authorities from manually submitting on TED. Contracting authorities that use a certified procurement platform can trust that their notices comply with the technical TED requirements and are published within the statutory deadlines.
For bidders and market observers, the eSender infrastructure means that notices are available on TED in a complete, structured and machine-readable form – which enables automated evaluation (e.g. by CPV codes or NUTS regions) and the integration into tender notification services. The current list of certified eSenders is maintained by the EU Publications Office and is publicly accessible.
