Denmark's country calling code
The country calling code for Denmark is 45, usually written as +45. You dial this code after your own country's international access prefix and before the Danish subscriber number whenever you call Denmark from abroad.
This reflects the current assignment shown in the standard list of country calling codes as consulted in November 2026. Calling code assignments rarely change, but if you are relying on an older directory or printed reference, check that it matches the current list.
What +45 covers, and what it does not
The +45 code applies to Denmark itself. The Faroe Islands and Greenland, which are linked to Denmark politically, are listed with their own separate calling codes rather than under +45:
- Denmark: +45
- Faroe Islands: +298
- Greenland: +299
If the number you need belongs to a person or organization in the Faroe Islands or Greenland, use that territory's code instead of +45.
How to dial a Danish number from abroad
The exact sequence depends on where you are calling from, because each country sets its own international access prefix (the digits that tell your phone network you are placing an international call). Your origin was not specified, so the sequences below use labeled placeholders.
From a mobile phone, the simplest method is to use the plus sign, which your network replaces with the correct international access prefix automatically:
+45 [DANISH SUBSCRIBER NUMBER]From a landline, or from any phone that does not accept the plus sign, replace the plus with your country's international access prefix:
[YOUR COUNTRY'S INTERNATIONAL ACCESS PREFIX] 45 [DANISH SUBSCRIBER NUMBER]What to confirm before you dial
The reference consulted for this guide confirms the country code but does not set out Denmark's internal numbering rules. Before relying on a full dialing sequence, confirm the following details:
- Your international access prefix: this depends on the country and sometimes the network you are calling from. Your phone provider can confirm it.
- The subscriber number: use the number exactly as given by the person or organization you are calling, and check whether it already includes +45.
- Trunk prefix handling: some countries use a leading digit for domestic calls that must be dropped when dialing internationally. The supplied evidence does not confirm how Danish numbers are treated, so if a Danish number is written with an unusual leading digit, verify the international format with its source.
- Number length: the supplied evidence does not confirm the standard length of Danish subscriber numbers, so a number that looks incomplete should be checked rather than guessed.
Recognizing a Danish number
A telephone number written in international format that begins with +45, or with an international access prefix followed by 45, is a Danish number. A number beginning with +298 or +299 belongs to the Faroe Islands or Greenland respectively, not to Denmark's +45 range.
