Quick answer: A security freeze restricts prospective creditors from accessing a credit file, which can make it harder for someone to open new credit in your name. It does not erase existing accounts or prevent every form of identity theft.
When might a freeze make sense?
A freeze can be useful when you are concerned about identity theft, after a data exposure, or simply as a preventive measure when you are not actively applying for credit.
What a freeze does not do
It does not close existing accounts, stop charges on an already compromised card, erase fraudulent information, or replace monitoring your statements and reports.
Freeze vs. fraud alert
They are different tools. A freeze restricts access to a credit file; a fraud alert asks businesses checking the report to take steps to verify identity. Rules and procedures can change, so verify current instructions with the nationwide credit bureaus and the FTC.
Applying for credit later
You can lift or remove a freeze when you legitimately need access for an application. Plan ahead and use the bureau's official process.
Next steps
Review the credit report guide and the FTC's identity-theft resources if you suspect misuse of your identity.
Sources and verification
For current consumer-credit information, use primary resources from the Consumer Financial Protection Bureau, Federal Trade Commission, and federally authorized credit-report sources. Card-specific rates, fees, grace periods, and reporting practices should be verified with the issuer.
