Area code: how do I call to and in Luxembourg?

To call Luxembourg from another country, you need to dial the international dialing code for Luxembourg followed by the country code and the local phone number. Here's how:

1. From most countries: Dial your country's international exit code (e.g., 00 for many European countries and several others), followed by the international dialing code for Luxembourg, which is +352, and then dial the local phone number in Luxembourg, omitting the first zero. For example, if the phone number in Luxembourg is 12345678, you would dial: `[International exit code]` + `352` + `12345678`.
2. From the United States and Canada: Dial the international exit code, which is 011, followed by the international dialing code +352 for Luxembourg, and finally the local phone number without the first zero. For example, if the phone number in Luxembourg is 12345678, you would dial: `011` + `352` + `12345678`.

To call from Luxembourg to another country, you also need to dial the international dialing code of the country you are calling, followed by the country code and the local phone number.

1. To call most countries: Dial Luxembourg's international exit code, which is usually 00, followed by the international dialing code of the country you are calling, and then the local phone number. For example, to call a number in France, you would dial: `00` + `33` + `[Local phone number in France]`.
2. To call the United States and Canada: Dial Luxembourg's international exit code, usually 00, followed by the international dialing code +1 for the United States and Canada, and then the local phone number. For example, to call a number in the United States, you would dial: `00` + `1` + `[Local phone number in the United States]`.
