How to Freeze Your Credit at All Three Bureaus (And Why You Should)

What we checked before calling this the right answer

We reviewed the governing federal law, the official freeze procedures at all three major bureaus, the FTC's own consumer guidance, and independent research comparing credit freezes to alternatives like fraud alerts and credit monitoring services. We also looked at real-world data on identity theft outcomes to confirm the freeze's track record. Our standard: does the evidence support this recommendation, regardless of what any institution says by default? In this case, the evidence is unusually clear.

• ✓
  Federal law confirmed The Economic Growth, Regulatory Relief, and Consumer Protection Act (2018) guarantees that security freezes are permanently free for all consumers at all three major bureaus — this is not a promotional offer that can be revoked.
• ✓
  Credit score impact verified A security freeze has zero effect on your credit score. The CFPB and all three bureaus confirm this explicitly: freezing only restricts new inquiries — it does not alter your credit history or scoring factors.
• ✓
  Effectiveness vs. alternatives compared The FTC's own data and the Identity Theft Resource Center consistently show that a credit freeze — not a fraud alert, not a credit lock, not monitoring — is the only measure that proactively blocks new account fraud rather than just detecting it after the fact.
• ✓
  All three bureau procedures reviewed We walked through the freeze process at Equifax, Experian, and TransUnion to confirm each can be completed online in approximately five minutes per bureau, with no cost at any step.

Different situations, but one clear winner for most people

Your circumstances — whether you're actively applying for credit, have already been a fraud victim, or just want long-term protection — affect which approach makes most sense right now.

Common alternatives that sound good but leave you exposed

Several products and approaches are widely marketed as identity theft protection — but the evidence shows they're either weaker substitutes for a freeze or purely reactive tools that do nothing to stop fraud before it happens.

• ✗
  Paid credit monitoring services (as a freeze replacement) — Monitoring services notify you after a fraudulent account has already been opened; they do not prevent it. A credit freeze stops the account from being opened in the first place. Monitoring is useful alongside a freeze for detecting other fraud types, but it is not a substitute.
• ✗
  Credit "locks" offered by individual bureaus — Bureau-branded credit locks (like Equifax Lock & Alert or TransUnion's TrueIdentity lock) are proprietary products, not the federally mandated security freeze. They may have different terms, may not be free in the future, and carry fewer legal protections than a statutory freeze. The real freeze is always the better choice.
• ✗
  Freezing at only one or two bureaus — Lenders may pull credit from any of the three major bureaus — and some use smaller specialty bureaus like Innovis or ChexSystems as well. If you only freeze at Equifax and TransUnion, a fraudster can still open an account through a lender that pulls Experian. Freeze all three. (For maximum protection, consider also freezing at Innovis and the NCTUE.)
