San Diego Gas & Electric is alerting customers to be aware of a scam that has impacted other utility customers in several states across the country.
The scam claims that President Barack Obama is providing credits or applying payments to utility bills.
In some cases, scammers have asked for Social Security numbers in order to allow for credits or to apply payments to customers' utility bills, presenting an identity-theft risk.
Pacific Gas & Electric issued a warning to its customers, too, and there have warnings in the South and the upper Midwest.
