Where is telephone country code 21?

Answer 1

Country code +21 (dialed as 00 21 from many countries) is an incomplete country code. You need one more digit.

Originally, +21 was planned to be a unified numbering scheme for North Africa, including Morocco, Algeria, Tunisia, and Libya. However, each of those countries has its own separate country code, and the unified scheme plans were abandoned. In 2011, country code +211 was assigned for South Sudan.

+211 = South Sudan

+212 = Morocco

+213 = Algeria

+216 = Tunisia

+218 = Libya

(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.)

Answer 2

Country code +41 (dialed as 00 41 from many places) is Switzerland, and area code +41 21 is Lausanne.
