Country Code & Virtual Numbers
Denmark's +45 code covers a numbering system with no area codes — every number nationwide is a flat 8 digits. Capital: Copenhagen · Business hours: 3:00 AM–11:00 AM EST.
// The Basics
What is the +45 country code?
Denmark's international dialing code is assigned by the ITU (International Telecommunication Union) and used for every call placed from outside the country.
Numbering format
Denmark uses no area codes — every landline and mobile number is a flat 8 digits, dialed identically nationwide.
Calling culture
Danish business culture values informality and directness — first names are used quickly, and calls tend to be efficient and to the point.
Did you know
Denmark's flat 8-digit numbering system means there's no way to tell which city a number is registered to just from its digits.
