Look at that fourth digit and get a good idea what your answer is. Do any area codes or prefixes within N. America begin with a 0 or 1? Numbers appearing like this are NOT to be trusted and contain deceit. Nothing's for free, either. This 'grant' rewards the caller ONLY as you'll be required to pay a price for money you'll never get. Foreigners randomly calling about computers, grants, money, or claiming to be from the IRS is never good.

they called me also and he gave me some code number to use at any western union and get cash of 8000$
