Is the city code the same as a postal code for accra Ghana?

Answer 1

The term "city code" usually refers to a telephone area code. The telephone area code for Accra, Ghana, is 030 (+233 30 in international format), with a 7-digit local number. Note that telephone numbers in Ghana changed in 2010; a 6-digit number in Accra was prefixed with 2 to make the new 7-digit number.

Ghana does not use postal codes.

(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.)
