Yes, B2B cold calling is legal in Germany, and it does not require an opt in. Section 7 (2) no. 2 of the German Act Against Unfair Competition (UWG) demands prior express consent only before you call a consumer. For any other market participant, meaning a business, presumed consent is sufficient. The whole legal question for a company entering the German market sits in that one word, presumed, and in whether you can justify the presumption.
Germany does not ban B2B cold calling. It applies a relevance test. A call is lawful when the specific circumstances allow you to presume a genuine business interest on the part of the person you are calling. Broad, undifferentiated dialling fails that test, legally and commercially.
What German law says about B2B cold calling
The rule sits in Section 7 UWG, which deals with advertising that unreasonably harasses the recipient. For telephone advertising, paragraph 2 no. 2 splits recipients into two groups, and everything follows from that split.
Calling a consumer is lawful only with prior express consent. Calling any other market participant is lawful if there is at least presumed consent. Other market participants include companies, tradespeople and members of the liberal professions. You can read the official wording in the German statute text, and an annotated version with case law references at dejure.org. Both are in German, which is one reason foreign teams often work from second hand summaries and end up with the wrong picture.
Two misconceptions are common among companies entering Germany. The first is that Germany prohibits cold calling outright. It does not. The second is that the business exemption works like a general permission, so any company number is fair game. It does not work that way either. Presumed consent is a presumption you must be able to support before you dial, not an argument you construct after a complaint arrives.
What presumed consent means in practice
Presumed consent may be assumed where the specific circumstances make a genuine business interest of the person called likely. The advertiser must, on reasonable assessment, be entitled to assume that the person called expects such a call or would at least be open to it.
In practice, that assessment comes down to three questions:
- Subject matter fit. Does the offer relate to what the company being called actually does?
- Commercial benefit. Could the company being called realistically benefit from it in business terms?
- No objection on record. Is there no recognisable objection and no documented refusal from that company?
All three can be answered before the first call. That makes this a question of preparation rather than of legal opinion. A target list built on industry, company size, technology in use or an identifiable need documents exactly the circumstances that matter. A list bought or scraped by volume documents nothing at all.
Where the presumption breaks down
The wider the list, the weaker the presumption. An offer that could be pitched to any company whatsoever carries no specific interest for the individual recipient. An objection, once expressed, also continues to apply. It has to be recorded and respected in every later campaign, including campaigns run by a different team or partner. That groundwork is the substance of compliant cold calling, and the reason research and lead qualification belong before the dial, not after it.
Why cold email in Germany is stricter than calling
Most foreign sales teams assume the opposite. Email feels lighter, so it looks like the safer opening move. Under German law it is the harder one. Section 7 UWG requires prior express consent for advertising by email as a matter of principle, and that applies in B2B as well. There is a narrow exception in Section 7 (3) for existing customers and for similar goods or services of the advertiser, combined with the option to object.
| Criterion | Cold calling B2B | Cold email B2B |
|---|---|---|
| Standard applied | presumed consent is enough | prior express consent as a rule |
| Legal basis | Section 7 (2) no. 2 UWG | Section 7 UWG, narrow exception in Section 7 (3) |
| Exception | no separate consent needed where circumstances indicate genuine interest | existing customers and similar goods or services of the advertiser, with the option to object |
| Effect on your campaign | a properly researched target list can be called | no consent and no existing customer relationship means no send |
For a market entry plan the consequence is concrete. If your home market playbook opens with a cold email sequence and treats the call as follow up, that sequence does not transfer to Germany unchanged. On the German market the conversation is usually the compliant way in, and email follows once consent exists.
Who can penalise you for a cold call in Germany
Two separate questions get merged here constantly: whether a call is lawful, and who can act against an unlawful one.
On the first question, the Federal Administrative Court ruled in 2025 that business phone numbers are not automatically open to advertising calls. Protection against unwanted advertising applies regardless of whether a consumer or a company is being called. The protection of privacy and of undisturbed business operations outweighs the commercial interest of the advertiser. The B2B rule stands, but it is not read generously.
On the second question, the Bundesnetzagentur, the German federal network agency, may impose fines only for unlawful telephone advertising directed at consumers. For calls to entrepreneurs, tradespeople and the liberal professions it has no competence to issue fines.
The amounts involved are set out in the statute. Section 20 UWG provides for up to 300,000 euros for breaching the prohibition on unlawful telephone advertising, and up to 50,000 euros for breaching the obligation to document consent.
This produces a pattern that surprises many companies arriving from markets with a strong regulator. In German B2B, the sanction usually does not come from a supervisory authority. It comes through competition law, in the form of warning letters, known as Abmahnung, and injunction claims brought by competitors or industry associations. That is a commercial risk with immediate cost and lasting obligations, not a regulatory fine. Planning your outbound around the regulator alone means planning against the wrong risk.
What this means for your German market entry
The legal test and the sales test ask the same question: why would this specific company be interested in this specific offer? Answer it before the call and you stay inside the legal framework while having better conversations. Skip it and you lose on both counts.
- Define the target segment by criteria you can explain, not by list volume.
- Record, for each segment, why the offer fits what those companies do.
- Log every objection and suppress that contact permanently across all campaigns.
- Treat calling and email as two different regimes, because under German law they are.
- Keep conversation notes so the agreed next step is traceable for whoever picks it up.
This is the reason many companies entering Germany work with a local partner rather than building an in house team first. At DialFox the research and the segment definition come before the first call, the conversation is held by a native German speaker, and the outcome reaches your sales team as a structured handover: the contact, the notes from the conversation and the agreed next step. Our market entry sales support is built around exactly that sequence, and the full sequence is described on our process page. If you want your own target list assessed before you start, you can book a consultation.
Frequently asked questions about B2B cold calling in Germany
Is cold calling businesses in Germany legal without consent?
It is legal where presumed consent exists. Section 7 (2) no. 2 UWG requires express consent only for consumers. For other market participants it is enough that the specific circumstances make a genuine business interest likely. You need to be able to explain what those circumstances were.
What counts as presumed consent?
The test is whether the advertiser, on reasonable assessment, may assume the person called expects the call or would be open to it. Three points are examined: the subject matter fit between offer and activity, the possible commercial benefit, and the absence of any recognisable objection.
Can I send a cold email instead to be safe?
No. Email is the stricter channel in Germany. Section 7 UWG requires prior express consent for advertising emails as a matter of principle, including in B2B. Without consent, only the narrow exception in Section 7 (3) applies, covering existing customers and similar goods or services of the advertiser, with an option to object.
Can the Bundesnetzagentur fine us for calling German businesses?
Not for B2B calls. The Bundesnetzagentur may impose fines for unlawful telephone advertising only where consumers are called. For entrepreneurs, tradespeople and the liberal professions it does not issue fines. The realistic exposure in B2B is a warning letter or an injunction claim under competition law.
How large can the amounts be?
Section 20 UWG provides for up to 300,000 euros for breaching the prohibition on unlawful telephone advertising, and up to 50,000 euros for breaching the obligation to document consent. On top of that, competition law adds the cost of a warning letter and the binding effect of a cease and desist undertaking.
