# Credit Freezing > Credit Freezing (also known as a security freeze) is a consumer protection mechanism that restricts access to a person's credit report, making it difficult for identity thieves to open new accounts in that person's name. Mandated as a free service in the United States by federal law, it requires consumers to individually contact the three major credit bureaus—Equifax, Experian, and TransUnion—to enact or lift the restriction. - URL: https://optimly.ai/brand/credit-freezing - Slug: credit-freezing - BAI Score: 95/100 - Archetype: Challenger - Category: Financial Services Regulation / Consumer Rights - Last Analyzed: April 11, 2026
