How to call Denmark: step by step

The full sequence is: exit code + 45 + local number.

  1. 1

    Dial your exit code

    From the United States and Canada that is 011. From most of Europe, Asia, and Africa it is 00. On any mobile you can simply press and hold 0 to get a + instead, which works from anywhere.
  2. 2

    Dial 45

    45 is the country calling code for Denmark. It never changes and it is the same from every country in the world.
  3. 3

    Dial the number exactly as written

    Denmark has no national trunk prefix, so the number you would dial locally is the same number you dial after +45. Nothing to strip.
  4. 4

    Check the time first

    Denmark is on CET/CEST (UTC+1/+2). Business calls placed outside local working hours are the most common reason an international call goes unanswered.

Worth knowing

Denmark abolished area codes in 1989. Every number is a flat 8 digits, and you cannot infer location from it.
