What a code is
The CPV is a tree of codes of 8 digits plus a check digit. The first two digits identify the division, the first three the group, the first four the class and the first five the category; the last three give more precision (Regulation 2195/2002, Annex I). Directive 2014/24/EU requires references to nomenclatures in public procurement to use the CPV (art. 23(1)), and a contract notice gives the CPV codes, per lot where there are lots (Annex V part C).
A code labels the subject of the contract. It does not say the supplier is eligible, that the buyer wants your exact solution or who wins.
Where keywords help
Buyers describe needs in their own words, in Portuguese or Spanish, with local terms and acronyms the code title does not use. A keyword catches those. It also brings noise when a word is broad or appears only in an annex.
A routine that works
- Start with the CPV division and group closest to what you sell, then add neighbouring codes your offer overlaps.
- Add two or three phrases a buyer would write, in each language you work in, and note new wording you find in the documents.
- Review results rather than assuming silence means no opportunity, and write down the query so you can tune it.
How to read a Sinal match
Sinal puts every notice in one shape (buyer, object, CPV code, value, deadline) and links to the original record. A match is a reason to open the notice, not an eligibility decision. Check which sources are covered on the Coverage page.
