AI Telemarketing Law Germany: UWG, Consent, Robinson List

Germany is where teams go looking for a do-not-call list and find a different system. There is no national phone registry to screen against. There is a statute that says who may be called, a duty to document consent, and a regulator that can fine up to EUR 300,000. For AI telemarketing in Germany, the question isn't "who is on the list?" It's "can I prove this person agreed?"

This guide covers the Gesetz gegen den unlauteren Wettbewerb (UWG), the fines, what the Robinson lists really are, and how to set up an AI calling campaign that fits. It's general information, not legal advice.

Key Takeaways

• Section 7(2) UWG treats an advertising call to a consumer without their prior express consent as an unreasonable nuisance, and consent given at the start of the call is too late.
• Calls to other market participants, meaning businesses, need at least presumed consent, and the law doesn't define that term.
• The Bundesnetzagentur can fine up to EUR 300,000 for unlawful consumer calls, and up to EUR 50,000 if you fail to document consent for 5 years.
• The Robinson lists are voluntary industry opt-out lists, mainly for postal mail, and they don't replace phone consent.

• Topcalls AI calls start from $0.25/min and Topcalls does not keep a do-not-call list, so consent proof stays with you.

1. Is AI telemarketing legal in Germany?

AI telemarketing is legal in Germany when the call is consented to. Section 7(2) UWG requires prior express consent for advertising calls to consumers, and at least presumed consent for calls to other market participants. A call placed by an automatic calling machine needs the addressee's prior express consent, whoever the addressee is.

The statute is short. Section 7(2) lists what counts as an always-unreasonable nuisance, and the first two entries matter for calling:

• Number 1: advertising by phone to a consumer without prior express consent, or to another market participant without at least presumed consent.
• Number 2: advertising with an automatic calling machine, fax or e-mail without the addressee's prior express consent.

You can read the full text at gesetze-im-internet.de. Whether a conversational AI agent counts as an "automatic calling machine" isn't spelled out in the text, and this guide doesn't rely on a ruling that settles it. The careful reading is to plan for express consent on every AI-placed advertising call, consumer or business.

2. When is a B2B call allowed in Germany?

A B2B advertising call is allowed when the business has given at least presumed consent. The UWG doesn't define presumed consent, so you need concrete reasons to think the company would welcome this call, not a general industry fit. When in doubt, ask for express consent first and keep the record.

Think of it as a ladder:

1. Express consent: the contact agreed to phone contact, in writing or by form. Safest, and the only version that holds for AI-placed calls under the careful reading above.
2. Presumed consent: facts in the situation point to interest, for example a prior inquiry about the exact product you now call about.
3. No basis: a purchased list and a hunch. This is where cease-and-desist letters come from.

The enforcement picture is different for business calls. The Bundesnetzagentur says it can only fine unlawful phone advertising aimed at consumers, not calls to businesses, tradespeople or freelancers (Bundesnetzagentur). But that doesn't make B2B calls safe. Under section 8 UWG, competitors and qualified associations can demand that you stop and refrain from repeating the conduct.

3. How big are the fines for unlawful phone advertising?

The Bundesnetzagentur can fine unlawful consumer advertising calls up to EUR 300,000 under section 20 UWG. A failure to document consent properly, or to keep the proof for at least 5 years, can cost up to EUR 50,000. Suppressing or faking your phone number on an advertising call is a separate offense, with fines up to EUR 300,000 too.

Read the official text of section 20 for the exact wording and the list of other offenses. The Bundesnetzagentur is the competent authority for the first two violations in the table.

4. What must you document for consent?

Section 7a UWG requires you to document a consumer's prior express consent at the time it's given, in an appropriate form, and to keep the proof for 5 years after the consent and after each use of it. You must hand the proof to the Bundesnetzagentur promptly when asked.

That means a consent record needs a few fixed fields: who agreed, when, through which channel, and the exact wording they saw. The Bundesnetzagentur also warns about consent that arrives too late: if someone is asked to consent only at the start of the call, "already too late," in the agency's words (our translation) (Bundesnetzagentur).

Two practical rules follow for AI calling:

• Collect before you dial: the consent step happens on a form, in a contract or in an inbound request, never inside the outbound call itself.
• Prove the source: if the consent came from a list vendor, get the vendor's proof for your use in writing, because the burden to show consent sits with you.

5. Is there a Germany do-not-call list, the Robinsonliste, for AI telemarketing?

No. Germany has no national do-not-call register for phone advertising, and the Robinsonliste isn't one. The Robinson lists are voluntary industry opt-out lists. The one run by the Deutscher Dialogmarketing Verband (DDV) is described by a state data protection authority as protection against postal advertising, with a 5-year entry that members of the association respect.

So what do you do with it? Treat the Robinson lists as one more signal for your suppression process, not as a legal safe harbor either way. Being absent from a Robinson list gives you no right to call, and a call isn't unlawful because someone signed up to one. Consent decides.

The state authority's leaflet is clear on the scope: the list helps against postal advertising, and for phone advertising the consent rule applies (LfDI Baden-Württemberg leaflet, 2020). The same leaflet points to a second Robinson list at robinsonliste.de.

Compare how other countries handle it. France runs a statutory registry, covered in our Bloctel guide, and the UK checks lists against the TPS, covered in the UK PECR guide. Germany's model is consent first.

6. How does GDPR sit next to the UWG?

GDPR applies to the personal data behind every call: names, numbers and recordings. It gives you a legal basis question, a transparency duty and an objection right, while the UWG decides whether the advertising call is allowed in the first place. Passing one test doesn't pass the other.

Recital 47 GDPR says direct marketing may be regarded as carried out for a legitimate interest. That supports processing data. It doesn't override the UWG's consent rule for the call itself. And Article 21 lets anyone object to direct marketing at any time, after which you must stop. For the wider picture across countries, see AI cold calling under GDPR.

7. Does an AI agent have to disclose that it's an AI?

The UWG has no AI line, but the EU AI Act's Article 50(1) expects systems that talk to people to say they're AI unless that's obvious. Build it into the opening: your company name, the reason for the call, and a clear statement that it's an automated assistant.

Our AI disclosure laws guide covers how the duty looks across markets. Also check the number side. Every advertising call needs a displayed number that leads back to your company, because suppressing it is its own offense.

8. How do you run a compliant AI calling campaign in Germany?

A compliant German campaign loads only contacts with documented consent, opens with an honest introduction and shows your number. Topcalls handles dispatch and conversation with AI voice agents and campaign settings. You provide consent data, keep the 5-year records and remove anyone who opts out.

1. Export only contacts with a consent record that you can produce on request.
2. Write an opening that names your company, states the reason and says it's an automated assistant.
3. Use numbers you own and display them on every call.
4. Set dispatch hours, weekdays and retries per campaign. Topcalls retries a lead 1 to 10 times, on the delays or fixed times you set.
5. Keep recordings and transcripts next to the consent record.
6. Delete or suppress contacts the moment they withdraw consent.

Topcalls AI calls start from $0.25/min depending on the country called. Topcalls doesn't keep a do-not-call list, so the suppression file is yours. Price a campaign with the ROI calculator, or use the same setup for lead qualification calls on inbound requests, where consent usually already exists.

9. When does AI telemarketing not fit Germany?

AI calling doesn't fit when your list has no consent trail. Bought lists with no proof, old inquiries that never mentioned phone contact and trade-show scans without a phone box all fail the test. More calls per hour only multiplies the exposure. It also fits poorly for sensitive sales where each call needs a trusted adviser.

Austria is stricter on one point, because the text of its telecom law names no B2B exception. See the Austrian rules for AI cold calling if your campaign crosses the border.
