How to Call Denmark from the US: A Guide for SMBs and Startups

You’ve got a key partner in Copenhagen or a remote team member in Aarhus — but how exactly do you call a phone number in Denmark from the United States? What’s the correct format, and what should you expect in terms of cost? 

If your business works with international clients, vendors, or collaborators in Denmark, this guide will walk you through everything you need to know to place a call quickly, correctly, and affordably. 

What’s the Denmark Country Code? 

The Denmark country code is +45. Whenever you call Denmark from outside the country, you’ll need to enter this code after your international exit code. It helps the phone system route your call to the right location, whether you’re trying to reach someone in Odense or Aalborg. 

How to Call Denmark from the US, Step by Step 

In Denmark, both landline and mobile phone numbers follow the same format: they are always 8 digits long and do not use area codes or a leading 0. The key difference lies in the starting digits, which indicate whether the number is mobile or landline: 

• Landline numbers typically begin with 3, 7, or 8. 
• Mobile numbers usually begin with 2, 4, or 5. 

For All Danish Numbers (Landline or Mobile): 

1. Dial 011 — This is the US exit code. 
2. Dial 45 — The country code for Denmark. 
3. Dial the Danish phone number — No area code or leading 0 is required. 

Example: If the number is 12 34 56 78: 

• From a landline: 011-45-12345678 
• From a mobile: +45-12345678 

Bonus Tip: 

If you’re using a smartphone, long-pressing the 0 key gives you the “+” sign, which acts as a substitute for the international exit code (011). 

Common Denmark Area Codes 

Denmark uses a uniform 8-digit phone number format for both landline and mobile calls. There are no separate area codes; the first few digits of the number typically indicate the region or carrier. 

A few common mobile prefixes in Denmark include: 

There’s no need to drop a leading 0, as Danish numbers do not include it. 

When Should SMBs Make International Calls? 

Small businesses and startups commonly make calls to Denmark for: 

• Project management with Nordic software teams 
• Sales and account follow-up with partners or clients 
• Vendor sourcing or procurement 
• Customer support across time zones 

Time zone tip: Denmark operates on Central European Time (CET), which is 6 hours ahead of EST and 9 hours ahead of PST. 

How Much Does It Cost to Call Denmark? 

Rates for international calls to Denmark vary widely. Traditional mobile and landline providers may charge $0.30 to $0.60 per minute, which adds up fast if you're making frequent calls.
