You can lock (or “freeze”) your credit for free by placing a security freeze with each major credit bureau, which blocks new lenders from opening accounts in your name while keeping your existing credit and scores intact.

Quick Scoop

  • A credit freeze (security freeze) is free by law at all three major U.S. bureaus: Equifax, Experian, and TransUnion.
  • You must place the freeze separately at each bureau; they do not share your request.
  • You can freeze and unfreeze online, by phone, or by mail, and it does not affect your credit score.
  • Use a temporary lift (or scheduled unfreeze) when you need to apply for a loan, card, or other new credit.

Freeze vs. Lock (What Are You Actually Doing?)

Short version: For “how to lock your credit for free,” you’re almost always talking about a credit freeze , because the true “credit lock” products from bureaus are often bundled with paid subscriptions.

  • Credit freeze (security freeze)
    • Free at Equifax, Experian, TransUnion by federal law.
* Blocks most new creditors from pulling your report, making it very hard to open new accounts in your name.

* Can be lifted temporarily or removed entirely at any time.
  • Credit lock (subscription feature)
    • Typically part of paid monitoring/identity protection plans, marketed as a “lock/unlock with one tap.”
* Functionally similar (blocks new-credit access), but you pay for the convenience and extras (alerts, bundled tools).

For a no-cost, set‑it‑and‑forget‑it approach that’s widely recommended in finance forums and consumer guidance, go with a credit freeze rather than a paid lock.

Step‑by‑Step: How to Lock Your Credit for Free (Freeze It)

You’ll repeat almost the same process at each bureau. Online is usually fastest.

1. Gather what you need

Have this ready before you start (for each bureau):

  • Full legal name and date of birth
  • Social Security number
  • Current address and possibly previous addresses
  • Email and phone number
  • Answers to identity‑verification questions (past loans, addresses, etc.)

2. Place a free freeze at Experian

Experian lets you place a free security freeze online, by phone, or mail.

  • Go to their security freeze/credit freeze page and create or log into an account.
  • Choose Add a security freeze on your credit file.
  • Set a PIN/password or account credentials you’ll use later to lift/unfreeze.

Experian also offers a separate credit lock product (subscription), so be sure you’re selecting the free security freeze option, not a paid lock plan.

3. Place a free freeze at Equifax

Equifax also must let you freeze your credit for free and give options to manage it online, by phone, or mail.

  • Create/log into your Equifax account.
  • Go to the Security freeze section.
  • Confirm your identity and activate the freeze for your Equifax report.

4. Place a free freeze at TransUnion

TransUnion processes freezes at no charge as well.

  • Create/log in to your TransUnion account.
  • Find the Credit freeze or Security freeze link.
  • Complete the verification and turn the freeze on.

5. Confirm all three are frozen

Once you’ve done all three:

  • Save screenshots or emails confirming the freeze.
  • Store your login credentials and any PINs in a secure password manager.
  • Consider also freezing smaller reporting agencies like Innovis and LexisNexis for extra coverage, as forum users often suggest this for more complete protection.

When You Need to “Unlock” for a Credit Check

A freeze is not permanent in the sense that you’re stuck; you can lift it any time, for free.

You have two main options:

  • Temporary lift for a time window
    • Example: Lift from March 10–17 while applying for a car loan, then let it automatically refreeze.
  • Temporary lift for a specific creditor
    • Some bureaus let you unlock only for one lender or one bureau pull.

To do this:

  1. Log in to each bureau’s account (Experian, Equifax, TransUnion).
  2. Choose Lift/Unfreeze and either:
    • Set a date range, or
    • Specify a creditor if the bureau offers that option.
  3. After the window passes or you manually refreeze, your file goes back to locked (frozen) status.

Forum users often report a pattern like: “Unfreeze for a car or card, get approved, refreeze the same day; the whole process takes just a few minutes.”

What Freezing/Locking Does and Doesn’t Do

Knowing the limits helps you avoid a false sense of security.

What it does

  • Blocks most new-credit checks (credit cards, loans, new cell phone lines, certain utilities), which stops most new‑account identity theft.
  • Has no impact on your credit score.
  • Can reduce unsolicited pre‑approved offers, since unfamiliar companies can’t easily pull your reports.

What it does not do

  • Does not block access by:
    • Existing creditors
    • Some employers
    • Government agencies and courts
    • Certain collection activities
  • Does not stop:
    • Fraud on existing cards or bank accounts
    • Non-credit identity fraud (tax refund fraud, medical identity theft, etc.)

So you still need:

  • Strong, unique passwords and a password manager
  • Two‑factor authentication on financial and email accounts
  • Regular monitoring of card and bank statements

Real‑World Forum Perspective (2025–2026)

Recent forum threads and discussions show a clear trend: people still strongly recommend freezing your credit, especially with so many data breaches and scam spikes discussed in 2024–2025.

Typical opinions:

  • Many posters emphasize that free freezes are one of the most effective defenses against identity theft if you’re not constantly applying for new credit.
  • People often complain that some bureau sites push paid lock products up front, making the free freeze option less obvious.
  • Users frequently report a “set and forget” strategy: keep credit frozen indefinitely, unfreeze only when applying for a big purchase or new card, then refreeze.

One popular post highlighted that requests to initiate, lift, or remove a freeze must be fulfilled quickly (often within one business day for online or phone requests), which keeps the process practical even when you need credit occasionally.

Simple Strategy You Can Follow

  1. Freeze first, at all three bureaus (Equifax, Experian, TransUnion).
  2. Store your logins and PINs safely using a password manager.
  3. Leave the freeze on indefinitely if you’re not actively applying.
  4. Temporarily lift the freeze when you need new credit, then refreeze after approval.
  5. Layer protection with good passwords, 2FA, and regular statement checks.

Used this way, “locking” your credit for free via freezes gives you strong, low‑effort protection against the most common forms of credit‑based identity theft today.
