Last Updated: January 9, 2026

Connecting with neighbors is essential for maintaining relationships. Germany and Denmark share a border and a history of strong trade. You might need to reach a supplier in Copenhagen. Perhaps you are checking on a friend in Aarhus. Clear communication lines are vital for these interactions.

Many people find international dialing confusing. Different codes and formats can lead to failed connections. This guide simplifies the process for you. We provide the exact steps to ensure your call connects instantly. For more general data on the region, you can check Denmark’s country profile.


Understanding the Basics of International Dialing

You cannot simply dial a local number to reach another country. The telephone network needs specific instructions. These instructions come in the form of codes. Think of these codes as a digital address.

An international call requires three specific components. Each part plays a critical role in routing your voice. Missing one will result in a failed call.

The three main components are:

  • Exit Code: This lets your carrier know you are leaving the national network.
  • Country Code: This directs the call to the specific nation.
  • Local Number: This connects you to the specific individual or business.

The German Exit Code (00)

Every call starting from a German landline begins here. You must signal the network first. The standard international exit code for Germany is 00.

You dial this before anything else. It unlocks the international gateway. This code is standard across most of Europe. However, mobile phones have a modern shortcut. We will discuss that shortly.

Denmark’s Country Code (+45)

You need to direct the call to Denmark. Every nation has a unique identifier. Denmark’s country code is 45.

You enter this immediately after the exit code. This tells the system to route the call to Danish networks. Memorize this number. It is the key to crossing the digital border.


Dialing Denmark from a German Landline

Using a landline is a traditional and reliable method. The process follows a strict sequence. You must enter the digits in the exact order.

Follow these steps for a landline connection:

  • Lift the receiver and wait for the dial tone.
  • Dial 00 (Germany’s exit code).
  • Dial 45 (Denmark’s country code).
  • Enter the 8-digit Danish subscriber number.

Example Scenario:

You need to call a business with the number 1234 5678.

You will dial: 00 45 1234 5678.

Troubleshooting Landline Issues

Sometimes calls do not connect. Check if your landline plan allows international dialing. Some office phones restrict these calls to save money. You may need to ask your administrator to unlock this feature.

Also, listen for the tone after dialing the country code. A fast busy signal usually means the number is invalid. Double-check the 8-digit sequence.


Dialing Denmark from a Mobile Phone

Mobile phones offer a more user-friendly experience. You do not need to remember the “00” exit code. Smartphone technology standardized this process globally.

The plus sign (+) is your best tool here. It replaces the exit code universally. It works regardless of which country you are calling from.

Follow these mobile dialing steps:

  • Open your phone’s keypad.
  • Hold down the 0 key until the + appears.
  • Dial 45 (Denmark’s country code).
  • Enter the 8-digit Danish mobile or landline number.
  • Press the green call button.

Example Scenario:

To call the number 8765 4321, you dial: +45 8765 4321.

Why Use the Plus (+) Symbol?

Using the plus symbol prevents errors. Different countries have different exit codes. The plus symbol automatically inserts the correct code for your location. This is perfect for travelers. You can save contacts with the +45 format once. They will work whether you are in Germany, Spain, or the USA.


Understanding Danish Phone Numbers

Denmark has a unique numbering plan. It is simpler than the German system. You do not need to search for city codes.

Most countries use area codes for specific cities. Germany uses 030 for Berlin, for example. Denmark does not use this system. Danish phone numbers are always 8 digits long.

The entire 8-digit string is the subscriber number. This applies to both landlines and mobile phones. You never drop a digit. You never add a city code.

Identifying Number Types

The first digits can sometimes tell you the number type.

  • Landlines: Often start with 3, 4, 5, 6, or 7.
  • Mobile Phones: Often start with 2, 4, 5, or 6.

This distinction does not change how you dial. You always dial the full 8 digits. This consistency makes dialing Denmark very efficient.

Time Differences and Business Hours

Timing your call is just as important as dialing correctly. You do not want to wake a business partner at midnight. Fortunately, calling Denmark from Germany is convenient.

Time Zone Alignment:

Both Germany and Denmark are in the Central European Time (CET) zone.

There is zero time difference.

If it is 2:00 PM in Berlin, it is 2:00 PM in Copenhagen. You do not need to calculate hours. You can call immediately.

Best Times to Call

Business culture in Denmark is punctual. Standard office hours are similar to Germany.

  • Business Calls: Monday – Friday, 09:00 to 16:00.
  • Personal Calls: Evenings until 21:00 are generally acceptable.

Avoid calling during lunch hours (12:00 – 13:00) for business matters. Danes value work-life balance. Avoid calling business numbers late in the evening.


The Cost of Calling Internationally

Cost is a major concern for international communication. Traditional carriers often charge high rates. Calling a foreign number counts as an international call, not EU roaming.

Factors influencing your bill:

  • Carrier Rates: Per-minute charges vary wildly.
  • Connection Fees: Some providers charge a flat fee to start the call.
  • Mobile vs. Landline: Calling a mobile in Denmark is often more expensive.

Standard plans can cost upwards of €0.20 to €1.00 per minute. A 30-minute business meeting could cost €30.00. This is not sustainable for frequent communication.

The Hidden Costs of Roaming

You might think your flat rate covers this. Often, it does not. EU roaming covers calls when you are abroad. It does not always cover calls from home to abroad. Check your contract carefully. Unexpected bills are common for cross-border callers.
