45 Country Code: Denmark (+45)
Country code 45 (+45) belongs to Denmark. Denmark uses the international dialing code +45, assigned by the International Telecommunication Union (ITU) under the E.164 standard. The ISO 3166-1 alpha-2 code is DK.
You will see the same code written several ways depending on origin: +45 (universal + prefix, works from mobile), 0045 (from countries that use 00 as their international exit code — most of Europe, Asia, and Latin America), 011 45 (from the US and Canada), 0011 45 (from Australia), or the bare 45. All refer to the same Denmark country code.
Denmark has no area codes — every Danish phone number is a flat 8 digits with no city prefix to learn. To call Denmark from abroad, dial +45 followed directly by the 8-digit number. Mobiles and landlines share the same numbering pool, distinguished only by the carrier issuing the number, so the same dialing rule applies for both.

Denmark Telephone System Facts
Calling Denmark Successfully: Common Mistakes & Best Practices
Most failed calls to Denmark come from one of four mistakes, not from network problems. The most common is mishandling the country code itself: Denmark uses +45 with no trunk prefix to remove, so you dial it as-is. The most frequent error is adding a leading 0 by habit — there is none in the Denmark number plan.
The second is misreading the area code on landline numbers — Denmark numbers may have variable formatting depending on the carrier and city, so confirm the area code with the recipient before dialing. The third is dialing during off-hours — Denmark uses Danish business hours and consumer phones are usually answered between 8 AM and 9 PM local time. The fourth and most expensive mistake is assuming your US carrier's WiFi calling feature makes the call cheap. It does not — see WiFi calling vs VoIP for international calls for why.
For scam-call awareness: +45 is the legitimate Denmark country code, and most unsolicited calls from +45 numbers are legitimate calls from Denmark-based businesses, hospitals, family members, or call centers serving US customers. Caller-ID spoofing exists, so if a call from a +45 number claims to be from a US government agency, your bank, or the IRS, hang up and call the agency back on its published number. Real authorities never demand payment over the phone.
