M 71
Architecture and urban planning practices, structural, building services and civil engineering consultancies, surveyors, testing laboratories and inspection bodies: for building product manufacturers, design software publishers and suppliers who want to meet the specifiers of an area.
Our database for France holds 1,577,933 records (as of 4 November 2026); they are not yet assigned to industries. The quote states the size available for this industry.
Export of the whole industry: €409 (full price). Selections by region, department or your own filters are quoted on request.
Official statistics: 110,135 businesses in France according to Eurostat, structural business statistics (sbs_ovw_act) (reference year 2024, data as of 30 September 2026). Division 71 architectural and engineering activities, technical testing and analysis. This is the size of the market, not the size of our database.
Choose 71.11Z and 71.12B, then the départements you deliver to. Add surveyors (71.12A) and laboratories (71.20B) only if your offer concerns them.
Our records do not yet carry a NAF code: selecting by activity (NAF subclass) will only be possible for records matched with the Sirene database (matching in progress). The quote states what can be done today: area and required fields.
The official figure for the industry includes vehicle inspection and testing laboratories. It is not the number of architects on the Order’s register.
Price of the whole industry: €409. A selection by region, sub-industry or required fields is quoted individually; the whole-industry price is not a price promise for the filtered selection.

Division 71 of the NAF combines design (architecture, engineering, surveying) with testing (technical analyses, testing and inspections). INSEE also classifies urban planning and landscape architecture here (71.11Z), as well as vehicle roadworthiness testing (71.20A), which is usually removed from a construction-oriented selection.
Neighbouring trades are classified elsewhere: interior decoration in 74.10Z, construction economists in 74.90A, building of detached houses in 41.20A, together with construction and public works.
| NAF rév. 2 | Official INSEE title | What the code covers |
|---|---|---|
| 71.11Z | Architectural activities | architectural design, urban planning, landscape architecture, planning agencies |
| 71.12A | Surveyor activities | cadastral surveying and boundary marking, hydrological and underground surveys, photogrammetry |
| 71.12B | Engineering, technical studies | engineering consultancies: civil, building, HVAC, electrical, acoustic engineering, construction project management |
| 71.20A | Car technical testing | vehicle inspection centres; exclude them to target construction |
| 71.20B | Technical analyses, testing and inspections | materials and acoustic testing, food hygiene analysis; not medical analysis |
Before contacting a practice, two public directories let you check its status:
The 15 columns supplied are described on the export page.
In a building project, the architect and the engineering consultancy often draft the documents that steer the choice of materials and equipment. For a manufacturer they are specifiers to meet before the tender, not direct buyers.
All engineering specialities share subclass 71.12B: structural, thermal, acoustic or civil engineering cannot be told apart by NAF code. Where the website is included in the export, it remains the most reliable way to check a consultancy’s speciality.
A self-employed architect often uses their own name as the practice name, so their business contact details are personal data. The GDPR requires informing the person of the source of the data (Article 14) and respecting their objection (Article 21).
As a manufacturer of aluminium windows and doors, we are looking for architecture practices (NAF code 71.11Z) and engineering consultancies (71.12B) in Loire-Atlantique, Vendée and Maine-et-Loire that publish a website, to offer product presentation meetings. How many records have an e-mail address, and how many already have a NAF code?
Use cases
Specification meetings with the practices and consultancies of a region.
Gauge the number of practices per département before hiring a sales rep.
Reach surveyors and testing laboratories.
Invite the practices of an area to a continuing education session.
Questions
No. Registration is checked in the public register of the Ordre des architectes, which also shows the mode of practice. Our export describes the business: company name, address, SIREN and SIRET once matched with the Sirene database, phone, e-mail and website where published.
Not by NAF code, as all engineering specialities share 71.12B. We deliver 71.12B for the chosen area; sorting by speciality is then done from the websites.
Yes, they belong to division 71 (subclass 71.20A). For a construction campaign, ask us to exclude them; a supplier of testing equipment may, on the contrary, want only them. Filtering by code applies to records already matched with the Sirene database; the quote states how many there are.
