Calling Denmark from United States
Dial 011 (the United States exit code), then 45 (Denmark’s country code), then the local number exactly as written. So +45 32 12 34 56 is dialled as 011 45 32 12 34 56. From a mobile you can dial +45 directly instead of 011.

Step by step
Dialing Denmark from United States
Four steps, and the third one is where almost every failed call goes wrong.
- 1
Dial 011: the exit code for United States
011 tells the United States network that the call is leaving the country. On a mobile you can press and hold 0 to type a + instead, which works from any country and any SIM; it is the more reliable option when you travel. - 2
Dial 45: the country code for Denmark
45 is Denmark's country calling code. It never changes and is the same no matter where you are calling from. - 3
Dial the local number exactly as written
Denmark has no national trunk prefix, so there is nothing to remove. The number you would dial locally is the number you dial after 45. - 4
Check the local time before you dial
Denmark is on CET/CEST (UTC+1/+2) and United States is on ET (UTC−5/−4). Work out the overlap before calling; the most common cause of an unanswered international business call is simply the hour.

One thing about Denmark
Denmark abolished area codes in 1989. Every number is a flat 8 digits, and you cannot infer location from it.
Frequently asked questions
How do I call Denmark from the United States?
Dial 011, then 45, then the local number. For example, +45 32 12 34 56 is dialled as 011 45 32 12 34 56.
What is the country code for Denmark?
+45. From United States you reach it by dialling 011 first, or by dialling + directly from a mobile.
How do I call a Denmark mobile from United States?
Exactly the same way as a landline: 011 + 45 + the mobile number. A Denmark mobile in international format looks like +45 20 12 34 56.
What is the time difference between United States and Denmark?
United States is on ET (UTC−5/−4) and Denmark is on CET/CEST (UTC+1/+2). Because several of these zones observe daylight saving on different dates, check the current offset rather than assuming a fixed gap.
Is it cheaper to call Denmark over the internet?
Usually, yes. Carrier international rates are typically far above VoIP per-minute rates, and calling from an owned local number also means the person you are calling sees a number they can ring back.
