Last updated: January 2026 · Legal basis: Art. 72 Directive 2014/24/EU, eForms Regulation (EU) 2019/1780, § 39 VgV, BVergG 2018

What is a corrigendum notice?

The corrigendum notice is the instrument provided for in procurement law for correcting errors, ambiguities or changes in a procurement notice that has already been published. It is necessary where errors are discovered after publication, where procurement requirements change, or where questions from tenderers require clarification of the procurement documents. The corrigendum is published on the same platforms as the original notice (for EU-wide procedures on TED/eNotices).

In EU notice terminology the corrigendum notice is referred to as a "Corrigendum" or "Change Notice".

Occasions for a corrigendum notice

Corrigendum notices are required in a variety of situations:

Correction of errors in the notice (for example, incorrect deadlines or incorrect contract value)
Amendment or supplementation of the specifications
Clarifications in response to tenderer questions that must be shared with all interested parties
Extension of the deadline for tenders or requests to participate
Amendment of the award criteria or their weighting
Correction of the CPV code or other classification details

Legal requirements

Not every amendment to the procurement documents requires a corrigendum notice; one is, however, always required where material information in the notice is affected. Where amendments materially affect the preparation of tenders, the tender deadline must be extended accordingly so that all tenderers have sufficient time to adapt their bids.

Extension of deadlines

Where the corrigendum notice contains material amendments, the deadline for tenders or requests to participate must be extended so that all tenderers can take account of the amended information. As a rule of thumb: the more material the amendment, the longer the extension. Minor corrections (for example, typographical errors with no substantive impact) do not require an extension.

Technical processing under eForms

Under the eForms obligation in force since October 2023, corrigendum notices are processed as a standardised "Change Notice" in the eForms format. Technical submission is handled via the EU's eNotices platform or compatible national procurement platforms.

FAQ

Must a corrigendum notice take the same publication route as the original notice? Yes. Where the original notice was published in the Official Journal of the EU (TED), the corrigendum must also be published there.

Can material changes to the subject of the contract be made via a corrigendum? In principle yes, but for very far-reaching changes a new notice may be required where the amended procurement no longer corresponds to the project as originally announced.

How many corrigendum notices are permissible? Procurement law does not set a maximum number. Frequent amendments do, however, indicate poor preparation of the procurement and should be avoided.
