Regulation and compliance

Is it legal to call customers with AI in Norway, Sweden and Denmark?

Yes for reminders and follow-ups, as long as the agent says it is an AI. Sales calls are harder: all three countries require prior consent for marketing by automated calling systems, nobody has ruled that an AI agent is exempt, and Denmark bans unsolicited sales calls to consumers outright.

Yes, in all three countries, but not for every kind of call. Reminders, confirmations and follow-ups on something the customer already has are not marketing, and an AI agent can make those calls anywhere in Scandinavia as long as it says it is an AI. Sales calls are different. Norway, Sweden and Denmark all require prior consent for marketing through automated calling systems, and nobody has yet ruled that an AI agent falls outside that rule. Denmark goes further: unsolicited sales calls to consumers are banned, whoever or whatever makes them.

Sources were checked on October 29, 2026. This is an overview of the rules, not legal advice.

One shared rule, three different systems

All three countries implement Article 13 of the EU ePrivacy Directive, Norway through the EEA Agreement. It requires prior consent for direct marketing by "automated calling and communication systems without human intervention". For calls made by a person, each country chooses its own system. That is why the consent rule for machines reads almost the same in all three marketing acts, while the rules for human sales calls differ.

The open question is the same everywhere: is an AI agent that dials, talks and answers questions an "automated calling system"? The rules were written for machines that play a recorded message. An AI agent holds a real conversation, but it also dials and speaks with no person on the line. We have found no court ruling or regulator guidance in any of the three countries that settles it. Until one does, the careful reading is that the consent rule applies to sales calls made by an AI agent.

Norway

Markedsføringsloven § 15 bans marketing to natural persons through an "automatisert oppringningssystem (talemaskin)" without their prior consent. The second subsection exempts marketing where the person is "contacted orally by telephone", which is why a human telemarketer needs no consent. The Norwegian Consumer Authority's guidance on email and SMS marketing describes an automated calling system as automatic dialing that plays a recorded marketing message when the phone is answered, though it says its list of methods is not exhaustive. That points toward a narrower reading, but it does not settle the question for an agent that holds a conversation. The existing-customer exemption in § 15 covers email only, and a sales message left on voicemail counts as email under the act.

Consumer sales calls must also follow these rules, whoever makes them:

  • No calls to consumers registered in Reservasjonsregisteret or to anyone who has opted out with you directly (§ 12), and the list must be checked before the first call and in the month you call (§ 13 a). Existing customers may be called about similar products, but that is an exception to the register, not to the consent rule.
  • Weekdays 09:00–21:00 only, never on weekends or public holidays, and never from a hidden or unlisted number (§ 14).
  • Introduce yourself, say the call is marketing and say where you got the person's details (§ 16).
  • After an unsolicited phone offer, the consumer is bound only once they accept the offer in writing after receiving a written confirmation (angrerettloven § 10). Newspaper subscriptions and charities are exempt.

The register and the calling hours cover consumers only, but § 15 protects all natural persons, so an AI agent calling a named employee with a sales offer may need consent too. The Norwegian version of this guide goes into more detail.

Sweden

Marknadsföringslagen 19 § requires prior consent before marketing to a natural person through "uppringningsautomater eller andra liknande automatiska system" that are not operated by an individual. Under 21 §, ordinary calls made by a person are allowed unless the person has clearly objected, which in practice means checking the industry-run NIX-Telefon register. Screening your list against NIX covers the rule for human calls. It does nothing for the consent rule. The existing-customer exception in 19 § again covers email only.

If the call is meant to lead to a contract with a consumer, distansavtalslagen 2 kap. 3 a § has applied since September 1, 2018. At the start of the call the consumer must hear the company's identity, the purpose of the call and the name of the person calling. The contract is valid only if the consumer accepts your offer in writing after the call. How an AI agent meets the "name of the person" requirement has not been tested.

Both 19 § and 21 § protect natural persons, so a limited company's switchboard is outside them, but a sole trader is not. The rules may tighten: on July 9, 2026, the government appointed an inquiry into opt-in or a ban on telemarketing to consumers, due by January 15, 2027. More in the Swedish version.

Denmark

Forbrugeraftaleloven § 4 bans phoning a consumer to get a contract unless the consumer asked for the call in advance. It applies whether a person or an AI agent calls, and there is no exception for existing customers. The only exceptions are books, newspaper and magazine subscriptions, insurance brokerage, and rescue or ambulance subscriptions. A promise given in a banned call does not bind the consumer (§ 5), and the business can be fined (§ 34).

Markedsføringsloven § 10 adds a consent requirement for direct marketing to "nogen" (anyone) through "et automatisk opkaldssystem". Anyone includes companies. If an AI agent counts, that means consent for B2B sales calls too, and the consumer exceptions above no longer help. In 2016 the Danish Consumer Ombudsman found that a system leaving recorded sales messages on voicemail is one. No case yet covers an agent that holds a conversation.

For human sales calls to natural persons, sole traders included, the Robinson list (Robinsonlisten) and your own no-thanks list apply (§ 10, stk. 4). More in the Danish version.

Calls that are not marketing

In all three countries, a reminder about an appointment, a booking confirmation, a delivery notice or a follow-up on the customer's own case is not marketing. The consent rules and the opt-out registers do not apply. Data protection rules still do, including telling people at the start if the call is recorded.

The line can move in the middle of a call. A reminder that ends with "would you like to book another one?" has become marketing, so write into the call script what the agent must not offer.

Say that it is an AI

Since August 2, 2026, Article 50(1) and (5) of the EU AI Act have required that people who talk directly to an AI system are told they are dealing with an AI, at the latest at the first interaction, unless it is obvious. That applies in Sweden and Denmark now. The Act is not yet part of the EEA Agreement, so it is not Norwegian law, but it applies when the call reaches someone in the EU. We cover what the duty requires and how to put it in the opening line.

What is unclear, and when to ask a lawyer

Open in all three countries: whether a conversational AI agent is an automated calling system, and whether it changes anything if a person dials and hands over to the agent, or listens in and can take over. Also open: how Sweden's "name of the person" requirement applies to an AI, and how far the consent rule reaches in B2B. When you call across borders, assume the rules of the country you are calling apply.

Ask a lawyer before you put an AI agent on a cold sales list, consumer or business, before you rely on an exception such as Norway's existing-customer rule or Denmark's books and insurance, and before you design a human-handover model to get around the consent rule.

Where Threll fits

In Threll, your own editable call script decides what the agent says and must not say once someone answers. Threll warns if an outbound script is missing the basic rules: the agent gives its name, says it is an AI and who it calls for, honors a request not to be called again, never pressures, and offers to call back at a bad time. Outbound agents can also flag calls where the person asks not to be called again. Who gets called and when is decided before the call: checking registers, keeping consent records and respecting calling hours stay with you.

Threll.ai builds voice agents that call in Norwegian, Swedish, Danish and English. Start with the calls that are clearly allowed, reminders and follow-ups, and add sales once consent is in place.

Frequently asked questions

No. Reservasjonsregisteret, NIX-Telefon and Robinsonlisten belong to the rules for calls made by a person. If an AI agent counts as an automated calling system, sales calls to private individuals need their prior consent, and a number that is missing from a register is not consent.

Only with care. In Norway the existing-customer exception lets you call people in the register about similar products, but it does not lift the consent rule for automated calls. In Sweden the existing-customer exception covers email only. In Denmark there is no existing-customer exception for sales calls to consumers at all. The careful approach is to get consent to be called first.

Then you are in a much stronger position in all three countries. A call the customer asked for is not unsolicited, the Danish ban does not apply, and in Norway an explicit request overrides a registration. Say on the form that an AI assistant may make the call, keep a record of when and how the request was made, and keep the call to what the customer asked about.

It is not clear. The call was still dialed and opened by an automated system, and no court or regulator in Scandinavia has said that a later handover turns it into an ordinary call. If you plan such a model for sales calls to private individuals, ask a lawyer before you start.
