What country code is related to de?

Answer 1

".de" is the internet top-level domain for Germany, and "DE" is also the ISO-3166-1 code for Germany. (For example, prior to the introduction of the Euro, the currency code for German marks was DEM.)

The telephone country code for Germany is +49. You must also drop the trunk prefix 0 from the German domestic number; for example, Berlin's area code 030 becomes +49 30.

(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.)
