Never give personal information (name, age, address, etc.) to a stranger on the phone;
Never let a stranger on the telephone know when you will or will not be home;
Never let a stranger on the telephone know you are home alone; instruct babysitters never to tell anyone who calls that they are home alone with children;
Teach children old enough to be left alone never to tell a stranger who telephones that parents are gone. Teach them to say "my mom can't come to the phone now. May I take a message?"
Credit card/Social Security numbers, etc. Do not give out a credit card or social security number to someone who you do not know or whom you did not call.
WHEN PLANNING A TRIP
Consider having your telephone "put on vacation." (Notify the telephone company approximately two weeks before your trip, and arrangements will be made for an operator or a recording to state that your telephone is temporarily out of order each time it rings;
Use "call forwarding" if available in your area. (Call forwarding can give callers the impression that residents are home when they are actually away, by transferring your incoming calls to another telephone number. Your local phone company can provide you with further information).
