Dialing Codes Involved While Calling Luxembourg from the US
Calling Luxembourg from the US involves the US exit code, Luxembourg’s country code, and the complete Luxembourg phone number. These dialing codes play a crucial role in routing the call out of the United States and connecting it to the correct individual or business number in Luxembourg.
1. US Exit Code
The US exit code is 011. It tells your phone carrier that the call is going outside the US and should be routed through the international calling network. On a mobile phone, you can replace 011 with the + sign.
2. Luxembourg Country Code
Luxembourg’s country code is 352. You dial it after the exit code to route your call to Luxembourg’s telephone network. The country code is required for all international calls, whether you are calling a landline, mobile number, or business number.
3. Luxembourg Number Prefixes
Luxembourg does not use separate area codes, unlike many countries. Instead, fixed-line numbers may start with digits linked to a city or region, while mobile numbers usually start with a three-digit network prefix. These prefixes are already part of the full Luxembourg phone number, so callers should dial them exactly as provided.
Here are some common Luxembourg fixed-line starting digits:
Starting Digits | Common Location/Use |
| 22, 24 22, 26 22, 27 22, 4 | Luxembourg City |
| 54 | Esch-sur-Alzette |
| 80 | Diekirch |
| 81 | Ettelbruck / Reckange-sur-Mess |
| 72 | Echternach |
| 79 | Berdorf / Consdorf |
| 95 | Wiltz |
Common Luxembourg Mobile Prefixes
Mobile Prefix | Mobile Provider |
| 621 | POST Telecom |
| 651 | Eltrona |
| 661 | Orange |
| 671 | Join Experience |

4. Local Subscriber Number

Alternative Methods to Call Luxembourg from the US
Besides dialing through a regular telephone carrier, you can call Luxembourg from the US using social media apps, VoIP services, calling cards, or Wi-Fi calling. These options can help reduce international calling costs or make communication easier for both personal and business calls.
Wi-Fi Calling
Wi-Fi calling is a built-in feature in smartphones that allows you to place calls through a Wi-Fi network instead of relying on a mobile signal. You can usually make the call from your phone’s normal dialer. However, calls to Luxembourg may still be treated as international calls by your mobile carrier, so it is better to check your plan before dialing.
Calling Cards
Calling cards are prepaid cards used to make international calls at fixed or reduced rates. They can be helpful for occasional calls, especially when you do not want to use an app or a monthly calling plan. Before buying a calling card, check the per-minute rate, connection fee, expiry date, and any extra charges.
Social Media Apps
Social media apps like WhatsApp, Messenger, FaceTime, Viber, and Telegram allow voice and video calls to Luxembourg over the internet. These apps are useful for personal calls when both people use the same platform. When connected to Wi-Fi, interactions over these apps are free, but call quality depends on the internet connection on both sides. However, they may not be suitable if you need to call Luxembourg landline or mobile numbers directly.
VoIP Services
VoIP services let you call Luxembourg phone numbers over the internet using a virtual phone number. Unlike social media apps, VoIP can connect calls to regular landline and mobile numbers, even if the person in Luxembourg does not need to have the same app. It is often a better option for frequent international calls because most service providers offer lower calling rates than standard carrier charges.
