Where is telephone country code 423?

Answer 1

Telephone country code +423 (dialed as 00 423 from many places) is for Liechtenstein, a tiny nation sandwiched between Austria and Switzerland.

(The plus sign means "insert your international access prefix here." From a GSM mobile phone, you can enter the number in full international format, starting with the plus sign. The most common prefix is 00, but North America (USA, Canada, etc.) uses 011, Japan uses 010, Australia uses 0011, and many other countries use different prefixes.)

Liechtenstein is the smallest German-speaking country in the world and the only alpine country to lie entirely within the Alps. It is also the only German-speaking country not to share a common frontier with Germany. It is a constitutional monarchy divided into 11 municipalities. Much of Liechtenstein's terrain is mountainous, making it popular for winter sports. Many cultivated fields and small farms characterize its landscape both in the north lower land and in the south upper land. The country has a strong financial sector located in the capital, Vaduz, and has been identified as a tax haven. It is a member of the European Free Trade association. Liechtenstein is not part of the European Union.
