Telephone numbers in Liechtenstein (original) (raw)

Liechtenstein previously used the Swiss telephone numbering plan (+41) under area code 075. (This was dialled as +41 75 from outside Switzerland and Liechtenstein). However, on 5 April 1999, it adopted its own international code +423. Consequently, calls from Switzerland now require international dialling, using the 00423 prefix and the seven-digit number.
