The first phase of the 2010 US Census is underway as workers have begun verifying the addresses of households across the country. Eventually more than 140,000 US Census workers will count every person in the United States and will gather information about every person living at each address including name, age, gender, race and other relevant data.

The big question is how do you tell the difference between a US Census worker and a con artist? If a US Census worker knocks on your door, they will have a: badge, handheld device, Census Bureau canvas bag and confidentiality notice

You should ask to see their identification and their badge before answering questions. Never invite anyone you don’t know into your home. Census workers are currently only knocking on doors to verify address information.

Don't give your Social Security number, credit card or banking information to anyone, even if they claim they need it for the US Census. Remember, no matter what they ask, you really only need to tell the worker how many people live at your address. While the Census Bureau might ask for basic financial information, such as a salary range, you don’t have to answer anything at all about your financial situation.

Also, note again that that the Census Bureau won't ask for Social Security, bank account or credit card numbers nor will employees solicit donations. Anyone asking for that information is NOT with the Census Bureau.

Eventually, Census workers may contact you by telephone, mail or in person at home. However, the Census Bureau will NOT contact you by email, so be on the lookout for email scams impersonating the Census.
