The city of Harrisburg has opened a Census Help Office at City Hall.
Mayor Linda Thompson said it is important to get the right information because she has already been the victim of a census scam, Lancaster television station WGAL reported.
Thompson said that she received and filled out a census form a few weeks ago.
She did not realize it was a fake form until her legitimate census form arrived last week.
"I was just eager to be a leader in the city that fills it out and (thought) the census said they wouldn't ask for Social Security numbers, " Thompson said. "They even asked for my address and where I worked and my job title. So, there you have it buyer beware."
Thompson said she is now taking steps to prevent identity theft.
