By law, credit reporting companies must block identity theft-related information from appearing on a victim’s credit report. They must block unauthorized transactions, accounts, and inquiries. But to get unauthorized information blocked, you must provide necessary documentation. First, send a copy of your Identity Theft Report to each credit reporting company. Include proof of your identity including your name, address, and Social Security Number. Explain which information on your report resulted from identity theft and that the information didn’t come from a transaction you made or approved. Then ask the company to block the fraudulent information. If the credit reporting company accepts your Identity Theft Report, it must block the fraudulent information from your credit report within four business days after accepting your report, and tell the business that sent the fraudulent information about the block.
