What is locking your credit file?
In respect to this, what does it mean to lock your credit report?
A security freeze prevents prospective creditors from accessing your credit file. Creditors typically won't offer you credit if they can't access your credit reporting file, so a security freeze, also called a credit freeze, prevents you or others from opening accounts in your name.
Likewise, can you lock your credit report?
You can freeze your credit report at all three major credit bureaus, but it must be done individually. The security freeze isn't completely foolproof. Creditors and lenders with whom you already have accounts can access your credit report and score without you first unlocking your credit report.
Locking or freezing your credit file may help prevent criminals from opening fraudulent accounts in your name. If you don't plan on applying for any new credit in the near future and your state doesn't allow credit freezing fees, a freeze may be the way to go.
