How to Call the UK from Denmark? A Step-by-Step Guide

Before you call the UK from Denmark, you must know the correct international dialing format. This includes Denmark’s exit code, the UK country code, the UK area code or mobile prefix without the leading zero, and the local subscriber number.

Every international call from Denmark must begin with the exit code 00. This code signals your Danish network provider to route the call outside the country. But if you are calling from a mobile phone, you can replace the code with the + sign.

Once you dial the exit code, the next step is adding the UK country code. Every country has its own international code, and the UK’s is 44. This code routes your call from Denmark to the UK’s telephone network.

The UK uses area codes for landlines and prefixes for mobile numbers. Landline area codes identify a specific city or region, such as 020 for London, 0161 for Manchester, and 0121 for Birmingham. When calling from Denmark, you must remove the leading zero, so these become 20, 161, and 121.

For British mobile phones, the prefix usually begins with 07, but you must remove the leading zero when calling internationally. Both the area code and the mobile prefix help route your call to the correct destination, so entering them accurately is important to ensure the call connects without issues.

The final part of the number is the local subscriber number. UK landline numbers are usually 7–8 digits long, and mobile numbers typically begin with 7 and include 9 digits. Mobile numbers also drop the leading 0 when dialing internationally.

To call the UK from Denmark, combine Denmark’s exit code with the UK phone number format, which includes the UK country code 44, followed by the UK area code or mobile prefix without leading 0, and finally the UK local number.

To call a landline in the UK from Denmark, dial Denmark’s exit code 00 or +, then the UK country code 44, followed by the area code without the leading zero, and the local landline number.

• Step 1: First, dial the Denmark exit code, 00 or +.
• Step 2: Enter the UK’s country code, 44.
• Step 3: Dial the area code of the UK city or region you’re calling (remove leading 0).
• Step 4: Then, dial the local 7–8 digit landline number.

To call a British mobile number from Denmark, dial Denmark’s exit code (00 or +), then the UK country code (44), followed by the mobile prefix (7) and the 9-digit mobile number.

• Step 1: Enter Denmark’s exit code, 00 or +.
• Step 2: Enter the UK country code, 44.
• Step 3: Enter the mobile prefix “7” without the leading 0.
• Step 4: Enter the 9-digit UK mobile number.

To call the UK’s toll-free numbers from Denmark, dial Denmark’s exit code, 44 (UK country code), the toll-free prefix, and the remaining subscriber number.

• Step 1: Dial the exit code of Denmark (00 or +).
• Step 2: Dial the UK country code (44).
• Step 3: Dial the toll-free prefix (e.g., 800).
• Step 4: Dial the 7-digit subscriber number.

Note: UK’s toll-free numbers are generally meant for domestic calls only. If you try calling them from Denmark or another country, the call may not connect, or your Danish service provider may charge you international calling rates.

The best time to call the UK from Denmark is during UK business hours, typically 9:00 AM to 5:00 PM (UK time), which corresponds to 10:00 AM to 6:00 PM in Denmark. These hours ensure that businesses, customer support lines, and offices are available to answer your call. For personal calls, late afternoon to early evening in Denmark works well because it aligns with midday to late afternoon in the UK.

The UK is one hour behind Denmark for most of the year. Denmark observes Central European Time (CET) in the winter and Central European Summer Time (CEST) in the summer. The UK observes Greenwich Mean Time (GMT) in the winter and British Summer Time (BST) in the summer. However, the one-hour difference remains the same. Understanding this gap helps you plan your calls at a convenient time for both sides.

On average, calling the UK from Denmark costs between $0.23 and $0.94 per minute. The price can vary depending on your mobile carrier, calling plan, and whether you use a landline or mobile phone. Traditional carriers usually charge higher international rates, which often range from moderate to expensive depending on the destination and time of day.
