A credit freeze remains one of the strongest tools available against identity theft, and it costs nothing to use. Federal law requires the three national credit bureaus to freeze and unfreeze a credit file free of charge, yet many retirees still assume the protection carries a fee or a hassle large enough to skip it — a misconception that leaves accounts open to a scam that is entirely preventable.
What a credit freeze actually blocks
A credit freeze restricts access to a person’s credit report, which stops most lenders and other companies from opening new credit in that person’s name, according to the Federal Trade Commission’s consumer guidance on credit freezes and fraud alerts. Because opening a new credit card, auto loan, or line of credit almost always requires a lender to pull a credit report first, a frozen file effectively stops that step cold — even if a thief already has a Social Security number, date of birth, and other identifying details. The freeze does not affect a person’s existing accounts, does not lower a credit score, and does not prevent someone from continuing to use cards or loans already open.

Why it has to be done at all three bureaus separately
Credit reports are maintained independently by Equifax, Experian, and TransUnion, and a freeze placed with one bureau does not automatically extend to the others unless a consumer specifically requests it, per the FTC’s guidance. A person can contact any one of the three bureaus and, in most cases, that bureau is required to notify the other two, but confirming a freeze is active with all three individually is the more reliable approach. Placing a freeze means contacting Equifax at equifax.com or 800-685-1111, Experian at experian.com or 888-397-3742, and TransUnion at transunion.com or 888-909-8872, each of which asks for a Social Security number, date of birth, and current address to verify identity before the freeze takes effect. Each bureau issues its own PIN or password when a freeze is placed, and that credential — not a person’s memory of their own information — is what’s required to lift the freeze later, for example when applying for a new mortgage or credit card, so each PIN needs to be stored somewhere retrievable rather than assumed to be interchangeable across the three bureaus.
The two lesser-known bureaus most freeze guides skip
Equifax, Experian, and TransUnion are not the only companies that compile consumer reports lenders and service providers rely on. The CFPB’s list of nationwide consumer reporting companies also names Innovis, sometimes called the fourth credit bureau, and the National Consumer Telecom & Utilities Exchange, or NCTUE, which compiles account and payment history reported by phone, pay-TV, home-security, and utility companies. Because wireless carriers and utility providers can open new accounts using an NCTUE report without ever touching a file at Equifax, Experian, or TransUnion, freezing only the big three can leave that door open. Innovis freezes can be placed free of charge online at innovis.com or by phone, and NCTUE freezes can be placed through its consumer portal or by calling 1-866-349-5355 — neither charges a fee, and both freezes work the same way as the big three, blocking new accounts until the consumer lifts them.
How a freeze differs from a fraud alert
A fraud alert is a lighter-touch option: it tells businesses to verify a person’s identity before opening new credit, typically by contacting the consumer directly, but it does not block access to the credit report the way a freeze does. An initial fraud alert lasts one year, while an extended fraud alert — available to anyone who has filed an identity theft report at IdentityTheft.gov or a police report — lasts seven years and also removes the consumer from prescreened credit and insurance mailing lists for five years. The FTC notes a freeze is generally the stronger option for people who are not actively planning to apply for new credit, while a fraud alert can be more convenient for someone who expects to shop for a loan or card soon and wants to keep the process moving with an extra verification step rather than a full block.
Why a “credit lock” is not the same protection
Many bureaus also sell a “credit lock,” marketed through paid monitoring subscriptions as a faster, app-based alternative to a freeze. The FTC distinguishes the two clearly: a freeze is a right guaranteed by federal law, free at every bureau with no exceptions, while a lock is a private contract between the consumer and a single bureau, governed by whatever terms that bureau writes and can change. A freeze carries the legal protections of the Fair Credit Reporting Act; a lock does not carry the same guarantees, and some lock products still charge a monthly fee bundled with credit-monitoring services a consumer may not need. Anyone who wants the strongest, no-cost version of this protection should ask each bureau specifically for a freeze, not a lock.
Placing and lifting a freeze without paying a fee
Consumers can place a freeze by phone, mail, or through each bureau’s website, and can lift it temporarily — for a specific date range or for a specific lender — or permanently, at no charge in either direction. Federal law also lets a parent or guardian place a free freeze on a child under 16, and the bureaus will create a file for a child who doesn’t already have one specifically so it can be frozen; 16- and 17-year-olds can freeze and unfreeze their own files. The same protections extend to “protected consumers”: anyone with an appointed guardian or conservator, which covers many incapacitated adults whose finances are managed by a family member holding power of attorney. Because there is no cost and no limit on how many times a freeze can be placed or lifted, security experts generally recommend leaving a freeze in place by default and lifting it only when actually applying for new credit.
