Question: I am calling a country with country with country code “0030” – I do not recognize this number – what country is it? The phone number I was given is “0030 21 0520 xxxx.”
Answer: 0030 is the country code for Greece. The phone number is likely in Athens.
“00” is an international exit code (the number used to access the international switchboard) for most European countries. If ’00’ is dialed from a country that does not use that as its exit code (the U.S. and Canada use ‘011’, Australia uses ‘0011’, Japan uses ‘010’, many countries of the former U.S.S.R use ‘8’ – wait for the dial tone – ’10’), the call will not work.
“30” is the country code for Greece. It is the number that is dialed to reach Greece from the international switchboard.
The remainder of the number appears to be the format for a Greek phone number. The ’21’ signifies the area code for a landline in the Athens metropolitan area. The remainder of the phone number is separated into eight numbers (two blocks of four digits).
