Unless you're calling from East Africa (where 000 is a valid international access prefix), that's an invalid code.
Because different countries use different international access prefixes, and some countries use more than one for various specific purposes, it is customary to write an international phone number with the country code preceded by a plus sign, without the access prefix.
