Country codes never begin with zero, and should be quoted without the international access prefix because that prefix varies from country to country.
If '00' is your international access prefix (the most commonly used), then you are asking about country code +1 (North America = USA, Canada, etc.), area code 263 (unused code), which means it's an invalid code.
If '001' is your international access prefix, then you are asking about country code +263 (Zimbabwe), area code 13 (Victoria Falls).
