How to Freeze Your Child's Credit to Prevent Identity Theft

Your child's Social Security number is one of the most valuable pieces of information an identity thief can steal—and the theft may go undetected for a decade or more. Placing a credit freeze at all three major bureaus is the single most effective step parents can take to lock down a child's financial identity before anyone has a chance to exploit it.

Why Children Are Prime Targets for Identity Theft

A child's Social Security number is, in the language of fraudsters, a “blank slate.” Unlike an adult's SSN, which is already tied to a credit history, a child's number has never been used to open a credit card, take out a loan, or rent an apartment. That clean record is exactly what makes it so attractive.

Criminals use stolen children's SSNs to open credit accounts, take out loans, file fraudulent tax returns, and even apply for government benefits—all under a name different from the child's own. Because children rarely (if ever) check their credit, the fraud can continue for years before anyone notices. In many cases, the theft isn't discovered until the child applies for their first credit card, a student loan, or an apartment as a young adult—and is blindsided by a credit report full of delinquent debt they never incurred.

What a Credit Freeze Does (and Doesn't Do)

A credit freeze—also called a security freeze—restricts access to a credit file so that new creditors cannot pull it. Because most lenders won't extend credit without reviewing a credit report, a freeze effectively prevents new accounts from being opened in your child's name, even if a thief has the SSN in hand.

A freeze does not affect existing accounts, prevent employment background checks, or stop the child from applying for government benefits. It also does not prevent existing creditors from accessing the file. It is specifically a shield against new credit fraud.

Critically, for children who do not yet have a credit file, the bureaus will create one solely for the purpose of placing the freeze—ensuring there is a locked record even before any credit activity exists.

The Cost: Always Free

What You'll Need Before You Start

Because the freeze involves a minor's record, all three bureaus require identity verification by mail. You cannot freeze a minor's credit online. Gather the following documents before you begin:

• Child's birth certificate (to prove the parent-child relationship)
• Child's Social Security card (to confirm the SSN)
• Parent or guardian's government-issued photo ID (driver's license, passport, or state ID)
• Proof of guardianship, if you are not the biological parent (court order, adoption decree, etc.)

Make clear photocopies of all documents. Do not send originals—the bureaus do not return them. Keep copies of everything you send, along with the date you mailed each packet.

How to Freeze Your Child's Credit at Each Bureau

You must contact all three bureaus separately. A freeze at one bureau does not carry over to the others.

Equifax

Equifax provides a dedicated Child Identity Protection form for minors. Download the form from the Equifax website, complete it with your child's information and your own, and mail it along with copies of the required documents to the address printed on the form. Equifax will create a credit file for the child (if one doesn't already exist) and immediately apply the freeze.

Experian

Experian does not offer an online freeze option for minors. Write a letter requesting a security freeze for your child, include the child's full name, date of birth, and SSN, and mail it with copies of all required documents to Experian's Security Freeze Center. Experian will confirm the freeze in writing once it has been applied.

TransUnion

TransUnion offers two options for minors: you can submit a Child Identity Fraud form through the TransUnion website (which walks you through the process and tells you where to send documents), or you can mail a written request with copies of the required documents directly to TransUnion. Either way, the documents must be submitted by mail—the freeze itself cannot be placed entirely online for a minor.

How Long Does the Freeze Last?

A security freeze on a minor's credit stays in place indefinitely—it does not expire. The freeze remains until you, as a parent or guardian, submit a written request to each bureau to lift or remove it.

There is one important exception: teens aged 16 and 17 are permitted to request a freeze—or a temporary lift of a freeze—on their own behalf without parental involvement. This is worth knowing as your child approaches adulthood and begins building their own financial life.

When Your Child Is Ready to Use Their Credit

When your child is old enough to apply for a student loan, a first credit card, or an apartment, you'll need to temporarily lift or permanently remove the freeze. Each bureau lets you do this by submitting a request in writing or, once your child is an adult, online or by phone. A temporary lift specifies a window of time (such as 30 days) during which lenders can pull the file; a permanent removal ends the freeze entirely.

Plan ahead: lifting a freeze can take a few days to process, so submit the request before your child needs to apply for credit.

Freezing Credit Is Only One Layer of Protection

A credit freeze is a powerful tool, but it works best as part of a broader approach to protecting your family's privacy. Identity thieves often build profiles of their targets by harvesting information from data brokers—websites that collect and sell personal details including names, addresses, relatives, and more. That aggregated data can be used to answer security questions, bypass verification, or target children whose SSNs have already been compromised.

Services like PrivacyOn work to remove your family's information from 100+ data brokers on an ongoing basis, reducing the amount of personal data available to bad actors in the first place. Pairing a credit freeze with active data broker removal addresses both the financial and informational vectors that identity thieves exploit.

Quick Reference: Steps to Freeze Your Child's Credit

1. Gather documents: child's birth certificate, child's SSN card, your government ID, and proof of guardianship if applicable.
2. Make clear photocopies of all documents. Never send originals.
3. Download and complete Equifax's Child Identity Protection form; mail with document copies.
4. Write a freeze request letter to Experian's Security Freeze Center; mail with document copies.
5. Complete TransUnion's Child Identity Fraud form online or write a letter; mail document copies to TransUnion.
6. Wait for written confirmation from each bureau (allow 2–4 weeks).
7. Store all confirmations in a secure location for future reference.

Taking these steps now costs you an afternoon and a few stamps. Undoing the damage from years of undetected child identity theft can cost your child years of their financial future. A credit freeze is one of the highest-value, lowest-effort protections available—there is no reason to wait.
