This guide sets out the Fair Credit Reporting Act as an operating system: who is regulated, what may be reported and for how long, who may obtain a report, and what happens when the information is wrong. It works through the reinvestigation process on both sides — the agency's duties and the furnisher's parallel obligations — and explains why the routing of a dispute determines whether any claim exists. Separate parts cover identity theft remedies, including fraud alerts, freezes, identity theft reports, and the four-business-day block that most victims never use. The remedies part addresses negligent and willful noncompliance, statutory and punitive damages, limitations, standing after recent Supreme Court decisions, and preemption of state claims. The guide closes with employer and landlord obligations, specialty reporting agencies, and a dispute drafting standard.
