How to Lock Credit

A credit lock is a feature offered by each of the three national credit reporting companies (TransUnion, Equifax, and Experian) that restricts access to a consumer's credit report. It is similar in effect to a security freeze, but the two are not the same. A security freeze is a statutory right under the Fair Credit Reporting Act, while a credit lock is a contractual service governed by the company's terms of use. Locks are typically marketed for convenience, allowing a consumer to toggle access on and off through a website or mobile app.

To lock credit, a consumer generally must create an online account with each credit reporting company separately. The process usually requires providing personal information such as name, address, date of birth, and Social Security number, and answering identity-verification questions. Once the account is established, the consumer can navigate to the lock section and turn the lock on. Some companies may charge a fee for the lock service, while others offer it at no cost. Freezes, by contrast, are free by law. The lock remains in place until the consumer turns it off or the company's terms change.

Because locks are contractual, their terms vary by company and can change. For example, some lock agreements include arbitration clauses or limitations on liability. A lock may not provide the same legal remedies as a freeze if a creditor accesses the report improperly. Additionally, a lock only restricts access at the company that offers it; it does not automatically apply to the other two national credit reporting companies. Lenders and other entities with a permissible purpose under the Fair Credit Reporting Act may still access a locked report in certain circumstances, depending on the company's policies.

Consumers who want stronger statutory protections often use a security freeze instead of, or in addition to, a lock. A freeze is free to place, lift, or remove at each of the three national credit reporting companies. It also gives consumers specific rights under federal law, including the right to dispute unauthorized access. Both locks and freezes must be managed separately at each company. Some third-party services offer to manage locks across companies, but using them may require sharing personal information and agreeing to separate terms.

In practice, locking credit means using each company's designated lock tool, often through its mobile app. The exact steps depend on the company's interface, but the general pattern is the same: sign in, verify identity, and toggle the lock. Because locks are not federally regulated like freezes, the speed of locking and unlocking, any fees, and the dispute process are determined by the company's terms. Consumers can review their rights under the Fair Credit Reporting Act and consider a freeze as an alternative.
