OJEU (Official Journal of the European Union)

The OJEU (Official Journal of the European Union) is the EU's official legal gazette and the publication of record for all above-threshold public procurement. A contract notice only becomes legally binding under EU procurement directives once it appears in the OJEU; the practical, searchable interface for those notices is ted, which is the online supplement.

What is the OJEU?

The OJEU publishes EU legislation, decisions, and official announcements across three series. Procurement notices appear in the S (Supplement) series, which is what TED makes searchable and API-accessible. When a contracting authority in an EU member state issues a contract for goods, services, or works above the relevant procurement-threshold, it is legally required to publish the call in the OJEU S series before advertising the opportunity through any national channel. This sequencing rule means the OJEU is always first, and national portals or aggregators follow. The OJEU also receives mandatory eforms-structured data since 2023, ensuring that the notices it publishes carry machine-readable fields rather than unstructured text.

Publication in the OJEU also starts the clock for statutory standstill periods and minimum tender deadlines, so the publication date carries legal significance beyond mere visibility.

Why the OJEU matters for bidders

Understanding the OJEU's role explains why monitoring TED is a more reliable approach than relying on national portals: by law, the OJEU publication precedes domestic advertising, so a TED-first monitoring setup gives the earliest possible sight of any opportunity. The publication date also anchors contract calendar calculations. EU directives set minimum deadlines for the open-procedure and restricted-procedure in days from the OJEU dispatch date, so the dispatch date in each notice is the correct baseline for calculating when bid documents must be submitted.

FAQ

Is the OJEU the same as TED?

No. The OJEU is the official legal journal; TED (Tenders Electronic Daily) is its online searchable supplement. All procurement notices must appear in the OJEU to be legally valid, and TED makes those notices searchable and API-accessible.

Does the OJEU cover contracts below the EU thresholds?

No. Below-threshold contracts are governed by national rules and are not required to be published in the OJEU or on TED, though some member states voluntarily publish smaller contracts there.

What is the S series of the OJEU?

The S series (Supplement) is the section of the OJEU that contains procurement notices. It is published daily and is what TED presents in its searchable interface.
