Where is area code 230?

Answer 1

There is no area code 230 in North America (USA, Canada, etc.).

International telephone country code +230 is Mauritius, in the Indian ocean, off the east coast of Africa.

(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.)
