Denmark carrier lookup questions
Short, straight answers about what the lookup can and can't tell you.
How do I find out which network a Denmark number is on?
Run it through the lookup above: it checks live carrier and porting records and shows the network the number is on today. The prefix alone tells you which network a number range was first issued to - the table on this page lists them - but a Denmark number can move to another network and keep its digits.
How can I tell if a Denmark number is a mobile?
Enter it in the lookup above. It shows the line type - mobile, landline, VoIP, toll-free and more - from carrier records, without contacting the number.
What is the country code for Denmark?
Denmark uses the country code +45. Numbers are dialled the same way inside Denmark, just without the +45.
How do you write a Denmark phone number?
In international format a Denmark mobile number looks like +45 34 41 23 45, and inside Denmark like 34 41 23 45. Mobile numbers have 8 digits after the +45. The lookup also gives you the clean E.164 form (no spaces) that apps and SMS systems expect.
Which mobile networks are there in Denmark?
The official numbering data names 53 networks with Denmark number ranges. The ones with the most ranges are tdc, telenor, cbb mobil and simservice. Smaller networks often run on one of those, so a number can show a different carrier name in the live check.
Is the phone carrier lookup really free?
Yes. The lookup is completely free and needs no sign-up or credit card. We cover the cost of the live carrier check, so there are no hidden per-search fees.
Does the person know I looked up their number?
No. The lookup is completely passive - we never call, text or otherwise contact the number, and the carrier check reads routing records rather than reaching the phone, so its owner gets no notification of any kind.
