About Denmark Calling Code
To reach Denmark from another country, first dial the international calling code +45 — assigned by the ITU — followed by the local number. Denmark is located in Europe, in Northern Europe.
Denmark is known locally as Danmark — Copenhagen is the capital. When saving an international contact, write the number in full international format with +45 so it works from any country.
The +45 prefix comes from ITU-T E.164, the numbering standard that keeps Denmark's phone network addressable from anywhere in the world. Because Denmark sits in Northern Europe, its code is grouped with the surrounding countries rather than shared randomly.
Where the +45 Calling Code Is Used
The country code +45 is assigned to Denmark, located in Northern Europe, with the capital Copenhagen. This code is part of the international telephony numbering plan and is used for all calls made to Denmark from outside the country.
When a number is written as +45 …, the +45 prefix directs your call to the Denmark national network. After the prefix, dial the area code without its leading zero, then the subscriber number — the same pattern for landlines and mobiles.
ITU-T E.164 groups calling codes by world region; codes beginning with 4 cover the part of the world that includes Denmark, in Northern Europe. Storing numbers with +45 and omitting the domestic leading zero keeps contacts dialable from anywhere.
Denmark Phone Number Formats
The ITU E.164 format for Denmark numbers is +45 + area code + subscriber number, used for landlines and mobiles alike. Here is the general structure:
📱 Number Structure
- International format: +45 [area code] [subscriber number]
- From abroad: exit code + +45 + local number (drop the trunk prefix 0)
- Within Denmark: dial the local number directly
Numbering plans come in two shapes: open plans allow variable-length numbers with a trunk prefix, closed plans fix the length everywhere. Denmark follows the published pattern +45 XXXXXXXX. Either way the rule for calling in from abroad is identical: replace the trunk prefix with +45.
Time Zone in Denmark
The local time in Denmark follows the Europe/Copenhagen time zone (UTC+01:00 UTC). Check the time difference before you dial so your call arrives during waking hours.
Time differences matter when calling Denmark: if it is UTC+01:00 there, a morning call from Europe may reach Copenhagen in the afternoon, while callers in the Americas should check the offset to avoid late-night calls.
If Denmark observes daylight saving time, its UTC offset shifts by an hour twice a year. Double-check the current offset before time-sensitive calls, especially in spring and autumn.
Best Time to Call Denmark
Business hours in Denmark run roughly 09:00–18:00 local time. Because Denmark sits at UTC+01:00, the window in which it is polite to call lands at a different hour for every caller. The table below converts Denmark's working day into your own clock — and shows the hours to avoid so you do not wake anyone up.
| If you are in | Call Denmark between | Avoid calling between |
|---|---|---|
| London | 08:00–17:00 | 22:00–06:00 |
| New York | 03:00–12:00 | 17:00–01:00 |

| Singapore | 16:00–01:00 | 06:00–14:00 |
| Sydney | 18:00–03:00 | 08:00–16:00 |
Times shown are standard time and ignore daylight saving, which shifts the clock by one hour in countries that observe it — around the clock change, add or subtract an hour from every figure above.

Example: Calling Denmark Numbers in Practice
Here is how a typical call to Denmark works, depending on where you are calling from:
🌍 From the United States or Canada
- Dial the US/Canada exit code 011
- Dial the Denmark country code +45
- Dial the local number (area code + subscriber number, without the trunk prefix 0)
Example: 011 +45 [area code] [number]
🌍 From the United Kingdom or Europe
- Dial the international access code 00 (or use the + symbol on mobile)
- Dial the Denmark country code +45
- Dial the local number
Example: 00 +45 [area code] [number], or +45 [area code] [number] from any mobile phone
If the local number begins with a trunk prefix (commonly 0), remove it when dialing internationally — +45 takes its place. The remaining digits are dialed exactly as written.
