The most common international access prefix is 00, which would leave country code +06, but country codes cannot begin with zero.
A few countries use 000 as the international access prefix, which would leave country code +6, which is an incomplete code somewhere in the Asia/Pacific region.
(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.)
Country code +63 is the Philippines.
I believe that that is not a valid country code - in others words no country has that code.
If it starts with 00, it's an international number. Country code +20 is Egypt. If it starts with a 0, it's a domestic number, and area code 020 is London.
