Telephone country codes never begin with zero.
Country code +233, dialed as 00 233 from many places, is Ghana, and a number beginning with +233 24 is a mobile phone on the MTN network.
Country code +33, dialed as 002 33 from many places, is France, and a number beginning with +33 2 is in the northwestern quadrant of the country.
To avoid confusion, it is best to write an international telephone number in correct international format, beginning with the plus symbol and the correct telephone country code (e.g., +233 or +33), omitting any dialing prefix.
(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.)
0024 - is incomplete. The next digit after the 4 is needed to specify the country it belongs to. There are TEN countries with IDC beginning 0024 !

A telephone number is essentially your address within the telephone system. As with a postal address, it contains several layers of information. Your telephone number consists of a telephone country code, a city code or area code (in most, but not all, countries), and a subscriber number. You must dial the entire number, beginning with the country code, when calling from outside your own country, but you can usually dial only part of the number when calling locally or within your own country.
