Denmark numbering plan & how to dial
Denmark uses a closed numbering plan under country code +45: subscribers are reached with a single 8-digit number after the country code, with no separate area code to dial.
Denmark has 98% internet penetration and is served by 3 major mobile networks (TDC Group, Telenor Denmark, Telia Denmark). VoIP is permitted and regulated by DBA (Danish Business Authority / Erhvervsstyrelsen). The local currency is DKK and the primary language is Danish, which shape IVR prompts, SMS content, and business-hours handling.
Most European numbering plans follow ITU-T E.164 with a national trunk prefix that is dropped for international dialing, and cross-border VoIP is widely supported across the region.
Skipping the exit code
From the US you must dial 011 before the +45 country code to reach Denmark.
Adding an area code that doesn't exist
Denmark uses a closed plan — dial the +45 country code then the 8-digit subscriber number directly, with no area code.
Ignoring the time difference
Denmark runs on UTC+1. Check local hours before dialing so calls don't land outside business time.
Permitted — DBA regulated
Regulated by DBA (Danish Business Authority / Erhvervsstyrelsen)
- VoIP providers must register with the Danish Business Authority under the Telecommunications Act.
- Emergency service access (112) is mandatory for all VoIP operators serving Danish subscribers.
- GDPR is strictly enforced by Datatilsynet for all electronic communications service providers.
