After incorporating a company in Switzerland, many founders expect administrative tasks, not unexpected invoices. Yet this is exactly when fraudsters become active.
So-called “address book scams” target newly registered companies with deceptive offers that resemble official communications. For some international entrepreneurs, first-time founders, fiduciaries, and legal advisors, these schemes can be difficult to spot at first glance.
Understanding how they work is the first step to avoiding unnecessary costs and legal complications.
What are address book scams?
Address book scammers send unsolicited offers for listings in business directories that appear official or mandatory. These offers often look like invoices or requests to verify company information.
In reality, they are not linked to the Swiss Commercial Register or any public authority.
The goal is to trigger a signature or payment that creates a binding contract. According to SECO, these agreements often run for one to three years, with annual costs ranging from CHF 300 to CHF 1,700
The risk is highest shortly after incorporation, when company details are public, and founders are still navigating administrative processes.
How these scams typically work
The tactics are designed to create confusion and urgency, while appearing credible.
Many companies receive forms with pre-filled business details. They are asked to review and return the document. The layout often suggests a free service, while the actual costs are hidden in the fine print
In other cases, documents resemble invoices, sometimes even including payment slips. These create the impression that a payment is already due, when in fact the act of paying initiates the contract
Phone calls and emails are also used. A caller may claim that a listing already exists and request confirmation or cancellation. Returning a signed form can unintentionally activate a paid agreement.
Some providers even rely on in-person visits, presenting documents as simple updates or confirmations.
Why new companies are prime targets
Newly incorporated businesses are particularly exposed. Their information is publicly available, and they are often dealing with Swiss administrative processes for the first time.
Fraudsters take advantage of this moment. An invoice received shortly after publication in the Swiss Official Gazette can seem legitimate, especially for international founders unfamiliar with local practices.
Internal processes can increase the risk. Administrative staff or reception teams may handle incoming mail and sign documents without recognising the implications
How to recognise a fraudulent offer?
A few warning signs can help you identify suspicious documents early.
Requests to “verify” company details combined with a signature requirement should always be reviewed carefully. If pricing, contract duration, or the provider’s identity are unclear or hidden, this is a strong red flag.
Be cautious with invoice-like documents for services you did not explicitly request. Swiss authorities do not send unsolicited invoices for directory listings.
Another indicator is the use of small print to disclose key terms, or language that mixes free and paid services in a misleading way.
When in doubt, do not sign or pay. Take the time to verify the sender.
What to do if you have already signed or paid
If you believe you have entered into a contract through deception, it is important to act quickly.
Under Swiss law, such agreements can be challenged. SECO recommends contesting the contract in writing, stating that you were misled and consider the agreement non-binding
Do not pay further invoices and keep all related documentation.
If enforcement proceedings are initiated, you have the right to object within the required timeframe.
You can also report the case to SECO, which collects complaints and may take action when multiple businesses are affected
Prevention starts with clarity
The most effective protection combines awareness with simple internal rules.
Ensure that everyone handling administrative tasks understands that not all official-looking documents are legitimate. A clear principle helps: no document is signed or paid without verification.
For international founders and advisors, working with trusted partners reduces uncertainty and risk. Knowing which communications to expect makes it easier to identify those that should be ignored.
At Hoop, we believe incorporation should come with clarity from day one, including understanding what not to act on.
