The subscriber number
From the United States, dial 011 to place an international call, then 45 for Denmark, then the area code (drop any leading 0), followed by the local number. With Telvio you dial the same format — no prefix change needed.
Exit codes by source country
The exit code depends on where YOU are calling from. On mobile phones and VoIP apps, use + instead.

Common mistakes
- ✕ Using the wrong exit code. Each country has its own (US: 011, UK: 00). On mobile, just use +.
- ✕ Forgetting the country code +45. Without it, the call will fail or route locally.

Country codes that get mistaken for +45
A wrong country code does not fail cleanly. It connects — to a stranger in another country — and it bills. These are the codes a caller most plausibly dials instead of +45 when calling Denmark.

The reliable habit is to store Denmark numbers with the plus sign and the full code — +45 — rather than typing them each time. A number saved in full international form dials correctly from any country you happen to be in, and removes the whole class of mistake above.
Calling out of Denmark
To dial an international number from inside Denmark, start with the exit code 00, then the destination country code, then the number without its own trunk prefix. The exit code belongs to the country you are calling FROM, not the one you are calling.
On a mobile, press and hold the 0 key until a plus sign appears and dial the number in full international form instead. The plus tells the network to work out the exit code itself, so the same saved number dials correctly whether you are at home or abroad — no need to remember 00 at all.

Other European destinations, cheapest first
Rates vary by more than a factor of ten inside a single region, because each one is set by what the operator at the far end charges to accept the call. United Kingdom is currently the cheapest place we publish a rate for near Denmark.

The country code for Denmark is +45. Dial this after your exit code (or use + on a mobile) before the local number.
How do I call Denmark from the United States?
From a landline: dial 011 + 45 + the local number. From a mobile or a VoIP app like Telvio: dial +45 + the local number — the + works from any country without knowing its exit code.

Denmark does not use a trunk prefix, so you dial the local number exactly as-is after the country code.
