00 isn't part of the country code, it is a commonly used international access prefix. That leaves country code +0213, which does not exist. Telephone country codes never begin with zero.
Alternatively, if your international access prefix is 000 instead of 00 (i.e., you live in Tanzania, Uganda, or Kenya), then you're asking about country code +213, which is Algeria.
(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, and many other countries use different prefixes.)
