Sandusky Police Department officials are warning people to not return calls with an 809, 284 or 876 area code.
AT&T has notified people of a phone scam which requires people to return a call to a long distance area code. The 809 area code is the Virgin Islands; the others were unknown.
Many people have been lured into returning the calls because they believe it is about a family member who is sick or injured or has been arrested or died.
Returning the call leads to steep phone bill charges, as much as $2,425 per minute.
Assistant Chief Charlie Sams said there haven't been reports of the scam in the area, but encourages people to be cautious.
According to the information the police department received, phone companies are not taking responsibility for the charges accrued by making the calls.
