The Denmark country code is +45 — reaching one of the EU's most-digital economies, ~5.9 million Danes + ~7 million mobile subscriptions across TDC/YouSee, Telenor, Telia + 3. The home of Maersk, Novo Nordisk, LEGO + Carlsberg — Danish bank logins + MitID all expect a +45 mobile.
Denmark was assigned +45 by the ITU — placing it in zone 4 with its Nordic neighbours. Uniquely, Denmark has no area codes at all: every number is exactly 8 digits, dialed in full.
Denmark has used the +45 country code since the ITU placed it in zone 4 alongside Sweden +46, Norway +47, Finland +358, Germany +49, Switzerland +41 + Austria +43. The "5" suffix is unique to Denmark in zone 4. Greenland (+299) + the Faroe Islands (+298) are separate country codes — Denmark proper is +45 only.
Denmark's telephone numbering is administered by the Danish Energy Agency (Energistyrelsen). Four mobile carriers: TDC/Nuuday (YouSee — Denmark's largest), Telenor Denmark, Telia Denmark + 3 (Hi3G/Three Denmark). Telenor + Telia share a single network (TT-Netværket). 5G is deployed nationwide.
Denmark abolished area codes decades ago. Every Danish number — landline or mobile — is exactly <b>8 digits</b>, dialed in full with no trunk prefix. There is no leading 0 to drop. The first digit (2–9) once hinted at type/region (3 for Copenhagen-area landlines), but numbers are now largely non-geographic + fully portable.
Denmark runs on MitID. Every Dane uses MitID (the national digital ID, successor to NemID) to log into banking + government services — and it sends one-time codes to a +45 mobile. Copenhagen is a Nordic fintech + pharma hub (Danske Bank, Nordea, Saxo Bank, Novo Nordisk), and the Øresund Bridge physically links Copenhagen to Malmö, Sweden — one of the busiest cross-border corridors in the Nordics.
A Danish phone number in international format is written as +45 NN NN NN NN — always exactly 8 digits. Example: +45 32 12 34 56 for a Copenhagen-area landline, +45 86 12 34 56 for Aarhus, +45 20 12 34 56 for a mobile. Danish numbers are grouped in pairs for readability.
Because Denmark uses a closed 8-digit plan with no area codes + no trunk prefix, there is no leading 0 to drop — you always dial all 8 digits, both domestically + internationally. Mobile numbers commonly begin with 2, 4, 5 or 6; the old "3" range covers historic Copenhagen landlines.
From Nyhavn in Copenhagen to the LEGO House in Billund, every Danish number lives behind a +45 — all 8 digits, no area code. Pick a number that fits your customers anywhere in Denmark.
Every country uses a different exit code before +45. From any mobile, + replaces the exit code — so +45 32 12 34 56 works worldwide. Danish numbers are always 8 digits — never drop a digit.

+45 reaches a top Nordic digital economy + the home of Maersk, Novo Nordisk, LEGO, Carlsberg, Ørsted + Bang & Olufsen. MitID + every Danish bank verify with a +45 mobile.
MitID (the national digital ID, successor to NemID — used by virtually every Dane for banking + government login) + Danish banks (Danske Bank, Nordea, Jyske Bank, Sydbank, Nykredit) send one-time codes to a +45 mobile. Without a Danish number, MitID + bank logins are hard to complete.
A +45 line connects you to Danish industry — Maersk (world's largest shipping line), Novo Nordisk (the Ozempic/Wegovy maker + Europe's most valuable company), LEGO, Ørsted (offshore wind), Carlsberg, Bang & Olufsen, Saxo Bank + Copenhagen's fast-growing fintech scene.
Denmark's closed 8-digit numbering plan is one of the cleanest in the world: every number is exactly 8 digits, dialed the same way everywhere, with no area code + no trunk 0 to remember. <b>+45 32 12 34 56</b> is dialed identically from Copenhagen, Aarhus or abroad.
Denmark is one of the world's most cashless societies — MobilePay (used by nearly every Dane), Dankort + mobile banking dominate. A +45 number is essential for any business selling into the Danish digital-payments ecosystem.
Denmark runs on CET (UTC+1) winter, CEST (UTC+2) summer — the same clock as Germany, Sweden, Norway + Poland. Pan-EU + Nordic business hours align cleanly, and the Øresund Bridge keeps Copenhagen + Malmö on one timetable.
