Case in point: A recent Javelin Strategy & Research report -- the 2009 ID Fraud Survey -- found that, among identity theft victims, 38 percent said the perpetrator had obtained their Social Security number and used it in the crime. "It's certainly logical to say that you could eliminate 38 percent of your risk of identity theft by limiting access to your Social Security number," says Van Dyke.
'Your Social Security number, please'
Still, saying it and doing it are two different things. Many of the forms you encounter during the day -- at doctor's offices, at the dentist, at your child's school -- ask for Social Security numbers. Retailers may ask for it, too, when accepting a check for payment or before issuing check cashing privileges. Potential employers also need it, and they may even want a copy of the actual card, says Linda Foley, founder of the San Diego-based Identity Theft Resource Center (ITRC). You'll also be asked for it at your local Department of Motor Vehicles, car dealerships, pawnshops, drugstores -- even at the airport, should you lose your luggage, she says. In fact, you may be surprised at how far-reaching this practice is, says Foley.
"A few years ago, we were putting some of my mother's things into storage, and they wanted her Social Security number to use as a passcode," she says. "It's that prevalent."
Just because someone asks for it doesn't mean you have to comply, says Michael J. Arata, the author of "Identity Theft For Dummies," especially since there are only a handful of organizations that actually have a valid need for it. For instance, anytime you're applying for credit -- for a new credit card, a loan, new telephone or cellular service -- the creditor will need your Social Security number to run a credit check. You'll also need to provide it if you are applying for federal or local government benefits such as Social Security, Medicare or Medicaid, unemployment insurance or disability. Another example: If you or your children receive services or aid at the state or local level, such as free or reduced fee lunch or financial aid. The local motor vehicle department, thanks to the USA PATRIOT Act, has the legal right to ask for Social Security numbers, too. In addition, when you complete a cash transaction totaling more than $10,000 you'll be required to provide your number so that transaction can be reported to the Internal Revenue Service, says ITRC's Foley.
Medical professionals have their own impetus, says the ITRC's Foley. "The reason a doctor or a dentist asks for your Social Security number is that, should you die while under his or her care, they are required to put your Social Security number on the death certificate," says Foley.
Even so, fulfilling non-credit-related requests -- even medical-related requests -- is purely optional, says L. Jean Camp, an associate professor at Indiana University and the author of "Economics of Identity Theft." "The problem is that you have the right to say that you're not going to give out your Social Security number, but a business owner has the right to say he's not going to do business with you," says Camp. "Most companies aren't being malicious. They're just being cautious by giving themselves a way to track you down if you don't pay a bill."
Gracefully saying 'No'
One of the best ways to get out of giving your Social Security number to someone is to simply overlook it on your paperwork, says Arata. You may get by without a confrontation. If you're questioned, however, ITRC's Foley suggests being proactive. "The most basic thing you can do is ask the person or organization why they need it. One of the most powerful things you can say is, 'Is there a law or requirement that I must provide it to you, and can you tell me what it is?' You can also ask the person requesting your Social what will happen if you don't disclose it," she says.
Often, as in the case of a school or a charitable organization, they simply want it to use your number as a unique identifier. In that case, says Javelin Strategy & Research's Van Dyke, you'll need to start negotiating again. "Say, 'In order for me to become your customer, I really need you to find an alternative recordkeeping method because I know giving out my Social Security number places me at great risk.' When you say it like that you may get better results," he says.
