How to Block Your Social Security Number

Blocking access to a Social Security number is a simple but essential step in minimizing financial damage for victims of identity theft. It also can help shield information for those trying to maximize their privacy. After a SSN has been blocked successfully, protection can be optimized by freezing access to all credit reports.

When a credit card is stolen, illicit activity often can be shut down immediately by cancelling the card. This is not the case with when a Social Security number falls into the wrong hands, as the information can be used repeatedly unless steps are taken to protect these records. In addition to identity theft incidents, access to this information often is blocked in domestic abuse cases to increase the level of privacy for victims.

Blocking access to personal and financial information linked to your Social Security number will prohibit illicit or unwanted access to your files, which can prevent someone from stealing government benefits or learning your whereabouts.

Electronic and phone access to SSN information can be blocked by contacting the Social Security Administration directly. They will ask you to verify your identification and confirm your intention to block access to Social Security information.

Blocking your number will prevent access by anyone, including you. If conditions change or you need access to your information, the block can be lifted either permanently or temporarily by contacting the Social Security Administration.

For questions and assistance with blocking your SSN, you also can call the Social Security Administration toll-free at ​1-877-772-1213​, or visit a Social Security office.

Blocking access to information linked to your SSN may not prevent identity thieves from using it to open fraudulent credit card accounts, apply for medical insurance or borrow money. Freezing your file at Experian, Equifax and TransUnion prohibits third party access to your credit reports, which can prevent illicit accounts from being opened in your name. Freezing a credit report also can shield your address and financial information from other prying eyes.

Pre-existing creditors still may access your credit reports for the purposes of monitoring debt, collections and incidents of identity theft.

To freeze your credit files, visit the freeze page on the website of each credit reporting company to find agency and state-specific requirements. You can also freeze your credit report by calling each credit reporting agency.
