Building a Compliant List of Real Estate Agents in Your Area (Post-2026 Law)

You are a traditional agency agent, property manager, or independent negotiator. You want to map your territory: who are the other real estate players in your town or department, their specialties, their networks, their listing volumes. This mapping serves two concrete goals: identifying potential partners (co-agency mandates, mandate exchanges, commercial partnerships) and anticipating competition to sharpen your positioning.

The 2026 context adds a layer: since the entry into force of French law no. 2025-594 of 30 June 2025, B2C canvassing is strictly regulated. Building a file of real estate professionals (i.e. B2B) remains possible on the basis of legitimate interest, provided you comply with GDPR and the right to object.

Here is the method to build this list in a few hours, using public and compliant sources.

How many real estate agents in France and in your area

To size your project, here are some reference figures. According to consolidated 2026 statistics, France has approximately 49,700 active mandataires (independent agents) spread across 148 national and regional networks. Adding traditional agency agents, salaried negotiators, and independents outside networks, the total number of real estate advisors in France approaches 96,000 according to industry sources.

Scaled to your area: a mid-sized French department (~700,000 inhabitants) typically has between 300 and 800 active mandataires, plus 100 to 300 agency agents. An urban area of 50,000–100,000 inhabitants has 50 to 200. These volumes are manageable manually over a few hours to build a clean list.

Source 1: INSEE's Sirene registry for the administrative baseline

The Sirene directory is the primary source for identifying real estate structures in a given area. The main NAF code to filter is 6831Z (real estate agencies), supplemented by 6832A (management of real estate and other property) and 7022Z (business and management consultancy) for some wealth advisors.

Cross-referencing the NAF code with the department or postal code gives you, within minutes, the exhaustive list of real estate structures in your area — with SIREN number, official name, address, declared headcount, and creation date.

Limitation: Sirene does not distinguish mandataires (typically registered as SASU or sole trader) from agency agents (typically SARL/SAS). You need to cross with other sources for fine-grained qualification.

Source 2: official directories from networks and federations

The FNAIM (Fédération Nationale de l'Immobilier, France's national real estate federation) publishes an official directory of member agencies. The SNPI (Syndicat National des Professionnels Immobiliers, the national union of real estate professionals) publishes a second one. Both directories cover a large share of traditional agencies and can be filtered by city or department.

For mandataire networks, each major network (IAD, Capifrance, Safti, Megagence, Optimhome, etc.) publishes its own directory of active advisors with geolocation. To map the mandataires in a given area, browsing 8 to 10 network directories is enough to cover 70–80% of active professionals.

The INPI (Institut national de la propriété industrielle, France's industrial property office) also publishes the register of professional real estate cards (carte T for transactions, carte G for management). If you are looking for official cardholders in your area, this source is valuable but less easily accessible.

Source 3: Google Maps and Pages Jaunes for enrichment

Once the base list is built (Sirene + federation directories + network directories), Google Maps adds operational details: website, phone number, opening hours, customer reviews, storefront photo, Google score. For 200–500 records, manual extraction takes 4 to 8 hours; extraction using a dedicated scraping tool takes 30 to 60 minutes.

Pages Jaunes (the French business directory) sometimes adds complementary data (detailed trade categories, years in business, some legal notices). Use it as a cross-check, not as a primary source.

LinkedIn rounds out the human dimension: names of directors, actual team size, years of experience, stated specialties (luxury, new builds, viager life annuity sales, commercial). For qualifying a dozen priority partnership targets, it is the final precision tool.

Building the final file: recommended structure

For each mandataire or agency retained, your file should contain:

Identification: SIREN number, official name, trading name, legal type (independent mandataire / independent agency / network agency / property manager), affiliated network where applicable.

Location: postal address, postal code, city, department. GPS coordinates if you want a visual map (Google My Maps is free and sufficient for 100–500 points).

Contact: professional email, phone number, website, LinkedIn and Instagram accounts (real estate professionals communicate heavily on Instagram), name of the director or main contact.

Business profile: declared specialties (residential/commercial, new/old/viager, luxury), active listing volumes (visible on SeLoger, Leboncoin, Leboncoin Pro), seniority (creation date from Sirene).

Relationship status: "to contact", "in discussion", "active partnership", "direct competitor", etc. Free-text field for notes.

GDPR compliance: what you must absolutely respect

Building a file of real estate mandataires is lawful under B2B canvassing based on legitimate interest (Article 6.1.f of the GDPR). However, GDPR obligations remain mandatory.

Registering your processing activity. If you maintain this file in a professional context, it must appear in your records of processing activities (required for any professional structure processing personal data, even B2B).

Informing the individuals concerned. At first contact, you must identify your organisation, the purpose of the contact, and indicate the right to object. A standard mention such as "You are receiving this message as a real estate professional identified in our public sources. You may object to future contacts by replying to this message" fulfils the obligation.

Respecting the right to object. If a mandataire asks you to stop contacting them, you must remove them from your file without delay. Maintaining an internal opt-out list is mandatory and must be consulted before each outreach.

The CNIL (France's data protection authority) details precisely the rules applicable to the reuse of publicly accessible data for commercial canvassing.

Using the file: partnerships vs. competitive intelligence

Once the file is built, segment it according to your intent.

For potential partnerships (co-mandates, exchanges, referrals, introductions), prioritise complementary structures: if you specialise in older residential property, look for peers in new builds, commercial, or viager. Outreach is done by professional email, B2B, with a concrete and factual proposal.

For competitive intelligence, the file serves as an observation tool: listing volumes, median prices, communications, social media presence. No contact is needed — you use it internally to calibrate your positioning.

For mandataire recruitment (if you are a team manager in a network), the file identifies potential recruits in your area. Contact is made on the career dimension, not commercial, but remains governed by B2B legitimate interest.

The pragmatic tool for building the file

For 50 to 500 enriched records, the 100% manual method (Sirene + directories + Google Maps + LinkedIn cross-check) takes 8 to 20 hours depending on the level of qualification required. For a one-off sector mapping, it is doable.

For regular mappings or larger files, a combined scraping tool with Google Maps extraction + email finder + verification reduces the time to 2–4 hours for 500 records. Competing subscriptions range from €49 to €150/month depending on scope and modules.

outsend in free alpha covers exactly this scope: Google Maps extraction of structures by NAF code + area, Sirene enrichment, email qualification and verification, all in a single tool. For a mandataire structuring compliant prospecting activity, it is the built-in all-in-one tool available on application.

FAQ — List of real estate mandataires in a given area

How many real estate mandataires are there in France in 2026?

According to consolidated statistics from deveniragentimmobilier.com, approximately 49,700 active mandataires are distributed across 148 national networks. Adding traditional agency agents, salaried negotiators, and independents outside networks, the total number of real estate advisors approaches 96,000. Mandataires represent around 50% of all advisors, and their networks accounted for approximately 28% of the brokered market.

What is the NAF code for real estate agencies in France?

The main NAF code for real estate agencies is 6831Z (real estate agencies). Supplementary code 6832A covers property management. For wealth advisors and some asset managers, code 7022Z (business and management consultancy). For co-ownership managers (syndics de copropriété), code 6832B (legal structures for real estate portfolio management).

Where can I find the list of mandataires in a given town?

Four main sources: Sirene filtered by NAF 6831Z + postal code (the baseline), the directories of major national networks (IAD, Capifrance, Safti, Megagence, Optimhome, etc.), the FNAIM or SNPI directory for traditional agencies, and Google Maps for contact enrichment (phone, website, customer reviews).

Is it legal to build a file of mandataires to canvass for partnerships?

Yes. B2B canvassing based on legitimate interest (Article 6.1.f of the GDPR) remains permitted after the entry into force of the French law of 11 August 2026. You must: use publicly accessible data, identify your organisation at first contact, respect the right to object, and maintain an internal opt-out list. The CNIL has published a precise framework on the subject.

How long does it take to map 200 mandataires in an area?

Using the manual method (Sirene + directories + Google Maps + LinkedIn cross-check), allow 4 to 10 hours for 200 enriched records with professional contacts. With an all-in-one scraping tool, allow 1 to 2 hours.

What is the difference between an independent mandataire and a traditional agency agent?

An independent mandataire is a self-employed professional registered as a SASU or sole trader, affiliated with a network (IAD, Capifrance, etc.) that holds the professional card. They prospect and negotiate under their own name and earn a commission. A traditional agency agent is salaried or commissioned by a physical agency holding the carte T. Both hold a collaborator attestation, but their legal and tax status differ significantly.
