Telephone country codes never begin with zero. What you have is a telephone country code quoted with the location-dependent dialing prefix for international calls. However, in different places, 00, 001, and 0015 are all possible international dialing prefixes, making it impossible to know for certain what part of that number is the actual telephone country code.
If the prefix is 00, then it's country code +1, area code 516, which is Nassau County, Long Island, New York, USA.
If the prefix is 001, then it's country code +51, Peru, and a national number beginning with 6.
