Democratic and Republican politicians on Thursday both promised to enact new federal laws by the end of the year that would restrict some commercial uses of Social Security numbers, which are often implicated in identity fraud cases. "Whether Social Security numbers should be sold by Internet data brokers to anyone willing to pay, indistinguishable from sports scores or stock quotes... to me, that's a no-brainer," Texas Republican Joe Barton, chairman of the U.S. House of Representatives Energy and Commerce Committee, said at a hearing. Such a practice should not be allowed, he said, "period, end of debate."

In both the House and the Senate, there are at least three pieces of pending legislation that propose different approaches to restricting the use and sale of SSNs. Politicians have expressed astonishment at what they see as a rising identity fraud problem, frequently pointing to a 2003 Federal Trade Commission survey that estimated nearly 10 million consumers are hit by such intrusions each year. One bill, sponsored by Massachusetts Democrat Edward Markey, would require the FTC to make new rules limiting the sale and purchase of those identifiers, with exceptions for law enforcement, public health, certain emergency situations and selected research projects.
