Your Child's Credit Score Can Be Stolen Before It Even Exists
Synthetic identity fraud uses children's SSNs to build fake credit profiles years before discovery. Here's how to place a credit freeze and stop it today.
Most parents know to protect their own Social Security number. Far fewer know that their child’s SSN — a number issued at birth and used for nothing financial for the next 16 years — is actively sought after by identity thieves for a very specific reason: it’s clean. No credit history means no fraud alerts, no monitoring, and no one checking. A criminal can pair your 7-year-old’s SSN with a different name, build credit slowly over years, and by the time your child applies for their first college loan or apartment, the damage is already done. The average discovery lag for child identity theft is 10 to 16 years. Here is how to prevent it in about half an hour.
Key Takeaways
- Synthetic identity fraud uses a real SSN with a fabricated name and birthday — it’s harder to detect than traditional identity theft and increasingly common.
- The Identity Theft Resource Center estimates that child identity theft affects over 1 million US children annually, with the majority undetected for over a decade.
- A credit freeze at all three bureaus (Equifax, Experian, TransUnion) is free, reversible, and the most effective prevention tool available.
- Minors don’t typically have a credit file — but placing a freeze creates a “suppressed” file that cannot be activated by fraudulent applications.
- Tax identity theft using children’s SSNs is a separate but related risk that a credit freeze does not address.
What Synthetic Identity Fraud Actually Is
Traditional identity theft is when someone steals your complete identity — your name, SSN, and birthday — and pretends to be you. Synthetic identity fraud is more sophisticated: thieves take only your Social Security number and pair it with a completely fabricated name, birth date, and address. The result is a “synthetic” identity that doesn’t correspond to any real person — so there’s no real victim who will notice unauthorized charges on their account.
This is why children’s SSNs are particularly valuable. An adult’s SSN almost certainly has an associated credit file. Any application using it gets cross-checked against the credit history. A child’s SSN almost never has a credit file — so when a criminal creates a synthetic identity using it, the credit bureaus simply create a new file for the fake person and track the credit-building activity. No one is monitoring a 6-year-old’s credit score.
Criminals build synthetic credit profiles gradually: they start with a secured credit card, pay it on time for a year, add a second card, and eventually take out a personal loan. After two to three years, the synthetic identity has a 700+ credit score. At that point, they “bust out” — maxing every line of credit and disappearing. The discovery happens when your child, now 18 or 22, applies for their first credit card or apartment and discovers they have a $47,000 debt collection record under their SSN attached to a person they’ve never heard of.
How Widespread Is This?
The Federal Trade Commission received 1.1 million identity theft reports in 2023. Child identity theft is consistently underreported because victims don’t discover it for years. The Identity Theft Resource Center’s 2023 annual report estimates that minors account for roughly 1.3 million US identity theft incidents per year, making children one of the highest-risk demographic groups — partly because of the long discovery lag that allows fraud to escalate undetected.
The Carnegie Mellon CyLab Usable Privacy and Security Laboratory conducted a landmark study finding that children are 51 times more likely to be victims of identity theft than adults. The reason is the SSN exposure. Children’s SSNs appear in school records, medical records, pediatric insurance databases, government benefit applications, and tax filings — a broad attack surface across systems with varying security practices.
Data breaches are a primary sourcing mechanism. The 2023 MOVEit file transfer breach, the 2021 Accellion breach, and ongoing breaches of healthcare and insurance systems all exposed SSNs of minors. Once an SSN is in criminal circulation, it can be sold and resold on dark web markets for years.
How to Check if Your Child’s Credit File Exists
A child under 14 should have no credit file. If one exists, it was created fraudulently. Here’s how to check:
Equifax: Mail a request to Equifax Minor Child Minor Credit Freeze Program, P.O. Box 740241, Atlanta, GA 30374. Include your child’s full legal name, SSN, date of birth, and proof of your identity and your authority as parent/guardian. Equifax will confirm whether a file exists.
Experian: Submit through the Experian Minor Child Freeze portal at experian.com/help or by mail to P.O. Box 9532, Allen, TX 75013. Include the same documentation package as Equifax.
TransUnion: Submit through the TransUnion Minor Credit Freeze page at transunion.com or by mail to TransUnion LLC, P.O. Box 380, Woodlyn, PA 19094.
All three bureaus offer online tools for checking. The process is slightly different from freezing for adults because you’re acting as a legal guardian on behalf of a minor who has no existing credit relationship. Expect the process to take 3–10 business days via mail or up to 24 hours online.
If any bureau confirms that a credit file exists for your child, immediately request a copy of the file (you’re entitled to it under federal law), look for accounts or inquiries you don’t recognize, and file an identity theft report at identitytheft.gov, which generates an FTC Identity Theft Report — a legal document that credit bureaus and creditors are required to accept.
Step-by-Step: How to Place a Minor Credit Freeze
A credit freeze — also called a security freeze — prevents new credit accounts from being opened in your child’s name. It does not affect any existing accounts and can be lifted at any time. It is free under federal law (the Economic Growth, Regulatory Relief, and Consumer Protection Act of 2018 made all credit freezes free for all consumers).
Documents you’ll need:
- Your child’s Social Security card or a document showing the SSN
- Your child’s birth certificate
- Your own government-issued photo ID (driver’s license or passport)
- Proof of your address (utility bill, bank statement)
- If acting as a legal guardian (non-biological parent): court documentation of guardianship

Each bureau will confirm the freeze by mail, and they’ll provide a PIN or password needed to temporarily lift the freeze when your child is old enough to apply for credit legitimately. Store this PIN somewhere safe — losing it creates additional bureaucratic steps when it’s time to lift the freeze.
When to Lift the Freeze
You’ll need to temporarily lift the freeze when your child applies for their first credit card, student loan, apartment, or other financial product. This is called a “thaw.” You can lift the freeze for a specific creditor, for a specific time window, or permanently.
Most students will need their first thaw around age 18 when applying for student loans or college housing. At that point, contact each bureau with your stored PIN and specify the lift parameters. The process takes 15–30 minutes online and a few days by mail.
What a Credit Freeze Does NOT Protect Against
A credit freeze prevents new credit account openings. It does not prevent:
Tax fraud. If someone uses your child’s SSN on a fraudulent tax return to claim refunds, a credit freeze won’t stop it. This is a separate IRS problem. To address tax fraud risk, the IRS offers an Identity Protection PIN (IP PIN) — but the IP PIN program was not available for minors in most cases as of 2025. Monitor this at irs.gov/identity-theft-fraud-scams.
Medical identity fraud. If your child’s insurance or Medicaid information is used to bill fraudulently for medical services, the credit freeze doesn’t apply. Separately monitor explanation-of-benefits statements.
Social media and account fraud. The credit freeze is a credit-system tool. For broader digital identity protection, layer in strong password practices — our two-factor authentication guide for family accounts covers the complementary digital security layer.
Government benefits fraud. SSN-based fraud in unemployment, SNAP, or other benefit systems is tracked separately from credit systems.
Free Monitoring vs. Paid Monitoring
After you place a freeze, ongoing monitoring helps you catch any fraudulent activity that occurs outside the credit system.
Free options:
- AnnualCreditReport.com: One free credit report per bureau per year (now weekly as of 2021 under the COVID policy that was extended). Run this annually on your child’s file once they turn 14 to confirm the freeze is intact and no files have been added.
- IRS IP PIN: If available for your situation, request this for your child’s SSN at irs.gov.
- identitytheft.gov: A federal resource for reporting and recovery if fraud is discovered.
Paid options: Services like LifeLock, Experian IdentityWorks, and Aura offer monitoring across credit, dark web, and other databases. Costs range from $10–$30/month per family. They add value for families who have already experienced a breach or who have reason to believe their child’s SSN was exposed. For most families with a freeze in place, the free annual check is sufficient.
What to Watch For Over the Next 3 Months
- The FTC is finalizing updated rules on identity theft response for minors under COPPA 2.0, which may impose new requirements on data holders who suffer breaches involving children’s information.
- Several healthcare data breaches from 2024–2025 are producing delayed notifications as investigation timelines conclude — if you receive a breach notification letter, treat it as a prompt to immediately place a minor credit freeze if you haven’t already.
- The Social Security Administration has proposed changes to SSN issuance procedures for newborns that may add fraud-prevention flags from birth — watch ssa.gov for updates.
Frequently Asked Questions
Does my child need to be a certain age before I can place a credit freeze?
No. You can place a credit freeze on behalf of a child of any age, including newborns. The bureaus process freezes for minors at the parent’s or legal guardian’s request. There is no minimum age.
Will a credit freeze affect my child’s ability to get a job or be admitted to college?
Employer background checks and college admission processes do not use credit freezes in the same way that lenders do. A freeze on your child’s credit file will not affect their college applications or job background checks. When a legitimate lender or landlord needs to check credit at age 18, you temporarily lift the freeze.
My child’s SSN was in a data breach. What should I do?
Place the credit freeze immediately at all three bureaus. Also check identitytheft.gov for recovery steps. File a report with the FTC. Check whether the breached organization offers free credit monitoring — accept it, since it’s an additional layer. Monitor tax filing to ensure no one files a return using your child’s SSN before you file yours.
What if I can’t find my child’s original Social Security card to apply?
You can request a replacement Social Security card through the Social Security Administration at ssa.gov. You’ll need to provide identity documentation. Bureaus also accept other documentation showing the SSN such as the child’s Medicaid card, insurance card with SSN, or prior year tax return — call the specific bureau to confirm acceptable documents before mailing.
