Various public records in the United States, including some generated by the federal government, contain Social Security numbers (SSN) and other personal identifying information that could be used to commit fraud and identity theft. Public records are generally defined as government agency-held records made available to the public in their entirety for inspection, such as property records and court records. Although public records were traditionally accessed locally in county courthouses and government record centers, in recent years, some state and local public record keepers have begun to make these records available to the public through the Internet. While it is important for the public to have access to these records, concerns about the use of information in these records for criminal purposes have been raised. In 2006, these concerns were heightened when an Ohio woman pled guilty to conspiracy, bank fraud, and aggravated identity theft as the leader of a group that stole citizens' personal identifying information from a local public record keeper's Web site and other sources, resulting in over $450,000 in losses to individuals, financial institutions, and other businesses. Although we previously reported on the types of public records that contain SSNs and access to those records, less is known about the federal government's direct provision of records with SSNs to state and local public record keepers. Because of Congress's interest in information on these issues, we agreed to answer the following questions: (1) Which federal agencies commonly provide records containing SSNs to state and local public record keepers, and what actions have been taken to protect SSNs in these records? (2) What significant vulnerabilities, if any, remain to protecting SSNs in public records? IRS and DOJ are the only federal agencies that commonly provide records containing SSNs to state and local public record keepers, and in recent years, both have taken steps to truncate or remove SSNs in those records. These agencies provide property lien records to public record keepers, on which they traditionally included full SSNs for identity verification purposes. However, both agencies have recently taken steps to better protect SSNs in these records. Currently, IRS mandates the use of a truncated version of SSNs on tax lien notices, which displays only the last four digits of the SSN. However, the agency does not mandate SSN truncation on all lien releases it issues. In addition, many of DOJ's districts have begun to truncate or fully remove SSNs on the lien records they provide to public record keepers. However, because DOJ's districts act independently to issue lien notices, some continue to display full SSNs in these records. Independent of IRS and DOJ efforts in this area, some states have begun to remove SSNs in all public records they maintain, though this approach can be costly and may not be fully effective at protecting SSNs.
