Calling Luxembourg from United States
Dial 011 (the United States exit code), then 352 (Luxembourg’s country code), then the local number exactly as written. So +352 27 12 34 56 is dialled as 011 352 27 12 34 56. From a mobile you can dial +352 directly instead of 011.

Step by step
Dialing Luxembourg from United States
Four steps, and the third one is where almost every failed call goes wrong.
- 1
Dial 011: the exit code for United States
011 tells the United States network that the call is leaving the country. On a mobile you can press and hold 0 to type a + instead, which works from any country and any SIM; it is the more reliable option when you travel. - 2
Dial 352: the country code for Luxembourg
352 is Luxembourg's country calling code. It never changes and is the same no matter where you are calling from. - 3
Dial the local number exactly as written
Luxembourg has no national trunk prefix, so there is nothing to remove. The number you would dial locally is the number you dial after 352. - 4
Check the local time before you dial
Luxembourg is on CET/CEST (UTC+1/+2) and United States is on ET (UTC−5/−4). Work out the overlap before calling; the most common cause of an unanswered international business call is simply the hour.
