Most texts about sex work in the Canton of Geneva deal with spaces: with apartments that become salons, with zones, with rental contracts, with doors behind which monitoring happens. But Geneva’s prostitution law knows a second mode of operation that doesn’t need spaces at all — and which for that reason is regularly overlooked in practice: the escort agency.
In the law, it’s not a side topic but its own chapter with its own articles, its own police registry, and its own penalty schedule. And it’s defined so broadly that people fall under it who would never call themselves an „agency“: the person who answers the phone for a cut, who coordinates appointments, who places ads, who manages the profile. Whoever does this in the Canton of Geneva for payment is legally operating an agency — with all that comes with it.
This text explains where the line is drawn, which reporting obligations apply separately to agencies and sex workers, which office is responsible for what, and what is verifiable in 2026 — and what is not.
What Geneva law understands by an escort agency
The decisive source is the Loi sur la prostitution (LProst, RSG I 2 49) of December 17, 2009, in force since May 1, 2010, last amended in 2018. There is also the implementing regulation (RProst, I 2 49.01) of April 14, 2010.
The law distinguishes three forms of appearance: sex work in public space, salon sex work, and escort sex work. For the third form, Art. 15 LProst says two things:
- Paragraph 1: Escort sex work is that which takes place in motion — at the customer’s request, directly or through an agency.
- Paragraph 2: An agency is „any person or business that brings potential customers into contact, for payment, with persons who engage in sex work“.
This definition is remarkably lean. It requires no premises, no company, no trade register entry, no minimum number of mediated persons. It requires two elements: contact-making and payment. Everything else is incidental.
From this follows the distinction that matters in everyday life: Whoever works alone, places their own ads themselves, and operates their own phone themselves is not an agency — they mediate nobody except themselves. But as soon as a third person takes on this mediation work for others for money or a share of revenue, the construction collapses. The law applies exactly the same logic to salons: A room in which someone works alone and without involving third parties is explicitly not a salon (Art. 8 para. 3 LProst). We have described in detail elsewhere where this threshold lies in Geneva salon law — there, in practice the rental contract decides the status of the address. With the agency, by contrast, the mediation action decides.
Does this also apply to online profiles and channels?
The cantonal police answered this question publicly. In an interview with the Geneva weekly GHI (September 2023), the responsible brigade explained: If a virtual profile aims to bring sex workers and customers into contact, the person behind it must be registered with the brigade beforehand — namely as an escort agency, in order to be permitted to operate in the canton.
The brigade has been monitoring online for years, partly together with the unit for computer crime. This is the practical consequence of a definition that doesn’t presuppose spaces: It follows the activity to where it happens — on portals, in messenger channels, on profiles.
It’s important to be honest about the limits of this statement: It describes the practice of the authority, not a court ruling on every conceivable platform model. Anyone planning a business model in the gray area — ad portal, appointment assistance, social media management for a flat fee — should clarify the question beforehand directly with the brigade and not rely on interpretation from the internet.
The registration is not a permit application — and yet functions like one
The law consistently speaks of annonce, of registration. Formally, there is no „permit for an escort agency“. But if you look at the process, you see that registration functions like an authorization procedure: Only those who meet the requirements are registered.
Art. 16 para. 1 LProst requires that every natural person operating an escort agency register beforehand and in writing with the responsible authority — stating the number and identity of the persons who work through it. If the agency is operated by a legal entity, it must designate in writing beforehand the natural person who assumes the obligations under the law (Art. 16 para. 3). Whoever makes the registration is thus the responsible person within the meaning of the law (Art. 16 para. 4) — and remains so, with all the consequences.
Art. 17 LProst names the personal prerequisites: Swiss nationality or the necessary permit for self-employed activity in Switzerland, legal capacity, guarantee of integrity and solvency, a positive statement from the land use department regarding the spaces used — and no operating ban from the last ten years.
What documents are required
Art. 12 RProst and the cantonal information sheet list for the agency essentially the same as for the salon:
- Copy of an ID document
- Copy of the residence or settlement permit
- Certificate of legal capacity from the adult and child protection court (TPAE)
- Criminal record extract and certificates from the debt collection and bankruptcy office, all no older than three months
- a sample of the detailed receipts to be issued to sex workers — with breakdown by rent, advertising costs, other supplies and further services
- the list of persons working through the agency, with full identity
- Copy of the rental contract or the exact location of the premises
Registration with the brigade is free of charge. The appointment for this is arranged — unlike for sex workers who book online — by phone.
The point where many files get stuck: the spaces
That sounds paradoxical for a business that supposedly needs no spaces. Nevertheless, Art. 17 lit. d LProst and Art. 12 para. 3 RProst require a positive statement from the cantonal land use department confirming that the spaces used may be put to commercial use or that an exemption permit exists. Only after that does the brigade enter the registration in the register of responsible persons (Art. 12 para. 4 RProst).
Two points for precision: First, the regulation text still uses the old department name (aménagement, du logement et de l’énergie); since the 2018 cleanup, the law text refers to the département du territoire. This is the responsible office today. Second: This requirement was the subject of a federal court appeal against the LProst. The Federal Court annulled the original versions of Art. 10 lit. d and 17 lit. d in 2011 (ATF 137 I 167); the current wording with the departmental statement was reintroduced in 2017. If you read old information sheets or forum entries, you may be reading law that no longer applies.
Where in the canton such use comes into question at all is its own, quite convoluted story — we have broken it down in the map of permissible and impermissible addresses.
What applies after registration
Art. 19 LProst and Art. 13 RProst set out the ongoing obligations of the responsible person. They are almost identical to those in the salon, although the situation is completely different:
- Maintain records: constantly updated, always available „within the agency“ to the police — with identity, place of residence, type and validity of residence or work permit, arrival and departure dates, as well as services provided and amounts charged for them.
- Receipts: detailed, dated, countersigned by both parties; a copy remains available as well.
- Immediate notifications: every change among the mediated persons and every change in the personal prerequisites must be reported immediately and in writing (Art. 18 LProst, Art. 13 para. 1 RProst).
- Duty to alert: if the responsible person becomes aware of violations, they must inform the authorities.
- Health information: Sex workers and customers must be provided with the information compiled by the brigade on the proposal of the cantonal physician regarding transmitted risks (Art. 13 para. 4 RProst). In the salon, the same information hangs as a poster — the agency must actively pass it on.
- Personal and actual management: The agency must be personally operated; in the event of absence, an instructed substitute must be designated, the person must be easily reachable for the authorities. And: „le prête-nom est strictement interdit“ — the straw man is strictly forbidden (Art. 19 lit. f).
There is also the independence of sex workers. They remain self-employed; nobody may dictate to them the locations, times, practices, frequency, or clientele. An agency that dictates schedules or sanctions cancellations is no longer operating in the area of mediation but moving into criminal law.
Why agencies are harder to control — and what authorities do instead
The most honest analysis of this regime comes from Geneva’s financial control authority itself. The Cour des comptes report no. 85 from December 2014 on the evaluation of prostitution policy noted what no one has really refuted since:
- Agencies „very rarely“ have premises; a website and a phone number suffice for operation. The registered office can be in another canton or abroad, which considerably complicates on-site inspections.
- The inspection of registers and receipts — the actual instruments of the law — is ineffective with agencies because there is simply no one on-site to compare information with. The report explicitly recommended formalizing a procedure for this.
- To reach persons working through agencies at all, inspectors rented hotel rooms and arranged appointments while posing as customers. The report calls this essential but resource-intensive and unpopular with those affected — they lose time and income for an inspection.
- In numbers: By the end of 2013, the brigade counted 133 salons and 45 escort agencies (2010: 26). Agencies were sanctioned significantly less often than salons — and when they were, it was predominantly for opening and operating prerequisites, not for register or receipt deficiencies, which they couldn’t even be found to have.
There is no current public figure for agencies in 2026. What is documented, however, is the development in salons: The Tribune de Genève reported in October 2024 of still 58 active salons compared to 128 in 2018, some of which were closed on departmental order. And the brigade told GHI of an average of approximately 900 new registrations per year (951 in 2019, 783 in 2021, 812 in 2022); the TdG spoke in 2024 of over 700 new registrations yearly. If anyone tries to derive a total number of active sex workers in the canton from this, they’re calculating wrong — the brigade itself points out that registered persons need not be active year-round and many EU citizens only work a few weeks a year.
The straw man case: what the Federal Court decided in 2024
How seriously the Geneva authorities take personal management is shown by the judgment 2C_439/2023 of January 26, 2024. The facts are instructive because they combine agency and salons:
A Spanish national had submitted the registration form for an escort agency in 2013 and additionally registered two salons in 2015. On paper, she was the responsible person for all three businesses. Following warnings from 2016 onwards and several inspections — including the discovery of persons without valid work permits and incomplete salon registers — the Department ordered the definitive closure of all three businesses in 2022, a ten-year operating ban, and an administrative fine of CHF 2,000.
Decisive was the allegation of prête-nom (front person): The actual core tasks — recruitment, advertising and ad texts, accounting, contact with authorities and property management, security, accompaniment to official appointments — were handled by a third party who, due to substantial debt, could never himself have been registered as an operator. The Federal Court upheld the cantonal interpretation: whoever makes the registration bears the obligations, and whoever permits someone else to actually run the business violates Art. 19 lit. f LProst. The severity of the measure also held up — economic freedom was not violated because the ban only concerned activity as a responsible person of a salon or agency.
The sanctions ladder itself is regulated in Art. 21 para. 2 LProst: warning, temporary closure of one to six months with corresponding operating ban, or definitive closure with a ten-year ban. Independently of this, an administrative fine of CHF 100 to CHF 60,000 may be imposed (Art. 25 LProst). How these levels develop in practice and what legal remedies are available is explained in the analysis on Geneva’s sanctions logic.
The Other Side: Obligations of Sex Workers Themselves
Registration of the agency does not replace personal registration. Anyone practicing sex work in the Canton of Geneva — in a salon, through an agency, in a hotel, or from home — must be of legal age, have attended the mandatory awareness course in advance, and must personally register with the Brigade (Art. 4 LProst as amended in 2017).
The course is conducted by the association Aspasie: free of charge, no registration required, Monday to Friday at 11 a.m. at Rue des Pâquis 11, 5th floor, in several languages. The confirmation must be brought to the police appointment, which is why Aspasie recommends attending the course the day before. The procedure for both appointments is described step by step here.
Beyond that, the rest of the law continues unchanged:
- Residence: Citizens of EU/EFTA states can register online for up to 90 days per calendar year under the federal notification procedure, before each start of activity; a copy of the online notification must always be carried. For third-country nationals, a residence permit allowing self-employed activity is required.
- AHV: In the Canton of Geneva, sex workers are considered self-employed by the compensation fund, regardless of work location. Registration is the responsibility of the affected person; anyone engaged in gainful employment in Switzerland for less than three months per year is exempt from contributions.
- Taxes: Self-employed activity must be reported to the cantonal tax administration; personal data collected during registration are transmitted to it and to the Office of Population and Migration ex officio (Art. 4 para. 3 LProst).
- Municipal fees: The previously separately owed taxe professionnelle communale was abolished in the Canton of Geneva as of January 1, 2024 and compensated through an increase in profit tax. For self-employed persons, this eliminates the need for a separate municipal declaration.
- Request receipts: Agencies and salons must issue a detailed, countersigned receipt for each amount collected. Anyone who doesn’t receive one has no evidence in a dispute against excessive deductions.
A practical point often overlooked: anyone working through an agency may ask whether it is registered with the Brigade. An unregistered referral not only gets the referring person into trouble but creates an environment for sex workers without receipts, without registers, and without any official point of contact.
Responsibilities: Who Decides What
The Geneva model is heavily centralized. Municipalities — unlike in many German-speaking cantons — play no independent licensing role; they come into play through building and zoning law as well as through advertising and quiet hour regulations, not through their own sex work law.
| Task | Responsible Authority |
|---|---|
| Registration of sex workers, salon and agency managers, inspections, receipt of notifications | Cantonal Police, specifically the Brigade de lutte contre la traite d’êtres humains et la prostitution illicite (BTPI), Boulevard Carl-Vogt 17–19, 1205 Geneva, Tel. +41 22 427 71 40 |
| Administrative measures, operating bans, administrative fines | Competent Department (today Département des institutions et du numérique, DIN) |
| Opinion on permissible use of premises | Département du territoire |
| Tax registration | Cantonal Tax Administration |
| Health inspections and prevention measures | Direction générale de la santé / Cantonal Health Officer |
| Residence and migration matters | Office of Population and Migration |
| Mandatory course, consultation, support | Aspasie, Rue des Pâquis 11, Geneva |
Anyone coming to Geneva from another canton should examine this division carefully: it is not transferable. In Zug, for example, regulation runs almost entirely through the zoning plan rather than through a special law, and in Nidwalden licenses are tied to the business and not to the person. Geneva does both differently: the person registers, the person is liable — and the category „agency“ exists at all in only a few cantons. A referral with a seat outside Geneva that makes contacts in the Canton of Geneva does not automatically escape Geneva’s registration requirement; it merely makes inspection more difficult, as the Audit Office noted.
What Remains Open in 2026
Three things currently cannot be reliably quantified, and no source should tell you otherwise:
- How many agencies are registered today. The last published figure comes from the Audit Office report and refers to the end of 2013.
- How many referrals operate outside the register. Naturally unknown; the Brigade itself acknowledges that the overall picture has become harder to capture since the shift to the internet.
- How the wave of salon closures affects the escort side. Observing bodies report displacement movements; reliable cantonal statistics on this are not available.
The law itself is stable: the LProst was last formally cleaned up in 2018; the last major substantive revision — mandatory course, police register for managers, straw man ban, receipt requirement — came into force in 2017. An ongoing total revision is not apparent for Geneva. If you encounter reports on the internet about a „revision of the LProst 2025,“ check the canton: Jura revised its law of the same name in 2025, Geneva did not.
When It Gets Concrete
Only information from the responsible authority is binding. For the question of whether a planned activity qualifies as an agency, that is the BTPI — reachable by phone Monday to Friday from 9 to 11 a.m. For the use of premises, the Département du territoire. For sanctions and legal remedies, the DIN and, in case of dispute, the Administrative Chamber of the Court of Justice.
For everything beyond that — consultation, legal questions, health, exit, experiences of violence — Geneva has a dense and free network: Aspasie (022 732 68 28), the Centre LAVI (022 320 01 02) for victim assistance, SOS-Femmes (022 311 22 22) for professional reorientation, and CAMSCO for medical care without insurance.
The sober core of this text is: In the Canton of Geneva, whether a business is regulated is not determined by its size, but by its function. One person, a telephone, and a revenue share are enough to legally be an escort agency — with registration obligation, receipt requirement, straw man ban, and a sanctions ladder that reaches up to a ten-year operating ban. Whoever knows this before starting saves themselves a lot of trouble. Whoever only finds out when the inspection comes usually does not.
