Danish Phone Number Lookup (+45)

Unknown calls from Denmark

In Denmark daily life runs through MitID, MobilePay and e-Boks, so scammers try to get hold of exactly those. Typical calls involve fake bank or police staff asking people to approve something in the MitID app, while texts imitating PostNord or the tax authority request small payments. Danish consumer law strongly restricts unsolicited sales calls, which makes an unexpected pitch more suspicious. Because mobile and landline numbers look alike, newcomers to Copenhagen or Aarhus, international students and cross-border commuters from Sweden often cannot tell who an eight-digit number belongs to, and a quick lookup helps.

Denmark phone numbers at a glance

Country calling code: +45
Trunk prefix: None
Number format: Danish numbers have eight digits with no area codes and no trunk prefix. Mobile and landline numbers share the same eight-digit format, and the first digits do not reliably show the type of line.
Example (national): 33 12 34 56
Example (international): +45 33 12 34 56
Emergency number: 112 (emergencies), 114 (police non-emergency), 1813 (medical helpline in the Capital Region)
Telecom regulator: Danish Agency for Data Supply and Infrastructure (SDFI)

Denmark numbers have no trunk prefix, so the international form is simply +45 followed by the national number: 33 12 34 56 becomes +45 33 12 34 56.

How to tell what kind of Danish number called you

Mobile networks in Denmark

Common phone scams in Denmark

MitID approval scams

Someone posing as bank staff, the police or a public authority calls and asks you to approve a request in the MitID app to stop fraud or verify your identity. Approving gives them access to your online banking or lets them take out loans in your name. Never approve MitID for anyone who contacted you.

"Hej mor" messages

A text or WhatsApp message claims to be your child writing from a new number, quickly followed by a request to pay a bill via MobilePay or bank transfer. Danish police have warned about this repeatedly. Call your child on their usual number to confirm before paying anything.

Fake PostNord and Skattestyrelsen texts

SMS messages announce a waiting parcel or a tax refund and link to a convincing copy of the official site. The page asks for card details or MitID credentials. Danish authorities send messages through Digital Post or e-Boks, and PostNord tracking should be checked in its own app.

Report scam calls in Denmark

Report fraud to the Danish police (politi.dk) online or by calling 114. Unlawful telemarketing can be reported to the Consumer Ombudsman (Forbrugerombudsmanden). If you approved anything in MitID or shared card details, contact your bank immediately and block the card.

Stop unwanted calls

Denmark's Robinson list (Robinsonlisten), registered through the CPR system, lets residents opt out of addressed marketing. In addition, Danish consumer law generally forbids businesses from making unsolicited calls to consumers to sell goods or services.

Denmark number lookup FAQ

Can I tell if a Danish number is a mobile?+

Not with certainty. Denmark uses eight-digit numbers for both mobiles and landlines, and many ranges have been reused. Numbers starting with 2 are usually mobiles, but other blocks also contain mobiles, and porting means the operator cannot be read from the number.

Who called me from +45?+

+45 is the country code for Denmark. Since there are no area codes, the following eight digits do not reveal the region. The caller could be a business, a public authority, a private person, or a scammer spoofing a Danish number.

Are cold sales calls allowed in Denmark?+

Generally not. Danish consumer law prohibits unsolicited calls to consumers to sell goods and services, with limited exceptions such as certain insurance, newspapers and charities. A company that cold-calls you to sell something may be breaking the law, and you can report it to the Consumer Ombudsman.
