Identity theft is one of the fastest-growing crimes, and a stolen identity can take months to clean up. A credit freeze is the single most powerful — and completely free — protection available: it locks your credit file so no one can open new accounts in your name. In 2026, freezing and unfreezing your credit takes minutes online. This guide walks you through the entire process step by step.
What a credit freeze actually does
A freeze blocks lenders from viewing your credit report, which stops criminals from opening credit cards or loans using your stolen details. Your existing accounts keep working normally — your credit cards, mortgage, and bank accounts are unaffected. A freeze is free, does not hurt your credit score, and is the strongest default protection you can get.
Freeze with all three major bureaus
You must freeze your credit separately with each major credit bureau — Equifax, Experian, and TransUnion — because lenders may check any of them. Each bureau lets you freeze online, by phone, or by mail; online is fastest and takes about ten minutes per bureau. Save the PIN or password each bureau gives you, because you will need it to unfreeze later. Freeze all three bureaus — freezing just one leaves the other two wide open.
Unfreezing when you need credit
When you apply for a loan, credit card, or apartment, ask which bureau the lender checks, then temporarily lift the freeze for that bureau only. Most bureaus process temporary lifts within an hour, and you can set them to re-freeze automatically after a few days. Set the lift to expire automatically so you never forget to re-freeze afterward.
Freeze your children's credit too
Children are prime targets for identity theft because the fraud often goes undetected for years. Parents can freeze a minor child's credit by contacting each bureau with proof of identity and guardianship. Also consider a fraud alert if you have already been a victim — it tells lenders to verify your identity extra carefully. A frozen child's credit file prevents fraud that might otherwise stay hidden until they turn eighteen.
Set aside 30 minutes this week in 2026 and freeze your credit at all three bureaus. It is free, fast, and the closest thing to a one-time fix that identity protection offers.
