Telephone country codes never begin with zero.
Telephone country code +58, dialed as 00 58 from many places, is Venezuela, and a number beginning with +58 2 is a landline, but you need the next two digits to determine where in Venezuela.
(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.)
The telephone country code for Ghana is +233. The area code for Obuasi is 032, or +233 32 in international format. The local number is always 7 digits. Almost all telephone numbers in Ghana changed in 2010. An old Obuasi number of the form (0582) XXXXX changed to (032) 25X-XXXX.
