That depends on what portion of 0012 is your international dialing prefix.
If your international dialing prefix is 00, then you're asking about telephone country code +1, which is North America, including the USA, Canada, and 18 assorted Caribbean or nearby islands. You need the next three digits (i.e., two more) to narrow down the location any farther.
If your international dialing prefix is 001, on the other hand, then you're asking about telephone country code +2, which is an incomplete code, most likely in Africa. You need one or two more digits to identify the country.
If your international dialing prefix is 0012, then you haven't yet included any information about the actual telephone country code.
Because different countries use different prefixes for outbound international calls, it is often confusing if you include your prefix in a number. It is much less confusing to quote the number in correct international format, beginning with the single plus symbol and the actual telephone country code. Note that telephone country codes never begin with zero.
(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.)
