Danish Telephone Numbers: How to Boost Your Business

When people think of Denmark, they often picture design, sustainability, and a high standard of living. But Denmark is also a country where efficiency and trust define the way people communicate.

Whether in business or personal life, clear communication is highly valued. For companies aiming to connect with Danish customers, understanding the country’s telephone system—and leveraging a Danish virtual number—can make all the difference.

Denmark’s telephone numbering plan

Denmark uses a closed telephone numbering plan, meaning all telephone numbers consist of eight digits.

Unlike many other countries, Denmark has no regional area codes—a design that makes the system simple and user-friendly. Whether you are calling Copenhagen, Aarhus, or Odense, the number length remains the same.

Some key facts to call Denmark phone numbers:

• All Danish phone numbers follow an eight-digit format.

• Phone numbers are portable, meaning they are not tied to a specific location—any number can be moved anywhere in the country.

• The Denmark country code is +45. This is the code you must use for international calls to Denmark, after dialing your own country code to exit (the US exit code is 011). No area code is needed.

• 112 is the emergency number for police, fire, and ambulance.

• 114 is the non-emergency number for contacting the police.

The numbering plan is managed by the Danish Energy Agency, which regulates telecom services in Denmark.

The structure of the Danish telephone system follows the European Telecommunications Standards Institute guidelines.

Habits and culture in business

In Denmark, business culture is built on transparency, punctuality, and straightforward communication. People prefer clarity and dislike unnecessary complexity. Meetings usually start and end on time, and decision-making often involves consensus.

This culture extends to phone interactions as well: Danish customers expect reliability, quick responses, and professional conduct. A local or recognizable phone number plays an important role here, as it signals credibility and presence in the Danish market.

By using a virtual number from Belfabriek, your business can reflect these cultural expectations and show that you value direct communication with Danish customers.

How to call Denmark

Making an international call to Denmark is straightforward if you know the steps. To call Denmark from the US, you begin with the exit code 011. This is the international prefix that allows you to call outside the United States.

• First dial: 011 (the exit code).

• Next dial: 45 (the Denmark country code).

• Then dial the eight-digit phone number.

Example: If you want to call a local number in Copenhagen from the US, you would simply dial:
011 - 45 - XXXXXXXX

Because Denmark uses a closed numbering plan, you don’t need an area code when making domestic and international calls.

Two autonomous regions

Denmark is also responsible for two autonomous regions: Greenland and the Faroe Islands. These regions have their own unique telephone numbers and country codes, separate from mainland Denmark.

Why Danish virtual numbers matter

In today’s global market, appearing local is a major advantage. Customers are far more likely to trust a phone number that feels familiar. By providing a Danish phone number, you show that your business is accessible, professional, and ready to serve.

With Belfabriek, the setup is free of unnecessary complexity. Within hours, you can have your virtual number up and running, with all the tools you need to connect, respond, and grow.

Landline, mobile, and portability

In Denmark, both landline and mobile numbers follow the eight-digit structure. A mobile number is just as important for business as a landline, because Danish consumers love mobile communication and even expect businesses to be reachable via SMS and data services.

The fact that Danish phone numbers are fully portable makes the system flexible. A businesses can keep the same number even when changing location or telecom services.
