A child's Social Security number shows up on a credit application. Maybe a notice arrived in the mail. Maybe a lender sent a question about a form you never filled out. Either way, a number that belongs to a minor is being used to ask for credit. Your first job is to find out whether a credit file exists in your child's name. Everything else depends on that answer.
Why a child's number on a credit application deserves attention
The Consumer Financial Protection Bureau (CFPB) says children under 18 generally do not have credit reports. A file in a minor's name is therefore unusual. That is a reason to look closely.
The CFPB lists three usual explanations for such a file. A similar name may have led to a file created in error. An identity thief may have obtained credit in the child's name. Or the child may be an authorized user on an adult's card, or a joint account holder. Only a look at the file tells you which one applies.
No published guidance in the material we reviewed spells out how a lender is supposed to treat a minor's number on an application. So do not wait for the lender to sort it out. Treat the application as a warning sign, and check the bureaus yourself. The CFPB page on checking a child's credit report is the best place to start.
Check whether a credit report exists
A parent or guardian, or a caseworker for a child in foster care, can ask each nationwide credit bureau to search for a report in the child's name. The three are TransUnion, Equifax and Experian. Each has its own process for minors, so one clean search does not cover the other two.
- Contact all three. Make a separate request to each bureau.
- Check each bureau's website first. The CFPB says to do this because the steps can change.
- Expect a gap between search and copy. With TransUnion, a copy of a report may need to be requested separately by mail.

Mail takes time, so plan for it. A search that finds nothing is still an answer. Write down the date and the result. If a bureau says no file exists, that record helps if a file appears later.
Bureau-by-bureau steps
The CFPB describes each process in summary. That is enough to know where to go. It is not enough to know every form, so confirm details on each bureau's own site.
- TransUnion: an online Child Identity Theft Inquiry form. It shows whether a report exists in the child's name. If one does, TransUnion contacts the parent or guardian for more information.
- Equifax: parents or guardians must contact it by mail. The CFPB points to Equifax's website for how to get a minor's report and how to request a security freeze.
- Experian: an online portal for Child Identity Theft Protection forms. The CFPB says these can check whether a minor has a report, add a fraud alert for a minor, and add or remove a security freeze. Experian's child identity theft page lists its current steps.
When you write or call, ask plain questions. Does a file exist under this name and number? If so, what accounts or inquiries does it show? What do you need from me to place a freeze? How will you confirm in writing that the freeze is active?
Freezes, fraud alerts and your paper trail
A security freeze generally restricts access to a credit file, which makes it harder for anyone to open new credit with that number. A fraud alert asks creditors to take extra steps before opening new credit. The CFPB says each bureau has its own process for a minor, including how to freeze a child's credit. If a file turns up that you did not expect, a freeze is worth asking about right away.
Costs and timelines vary by bureau, and the material we reviewed does not state them. Ask each bureau before you rely on any number or deadline. Also ask how to lift the freeze later, since you may need to do that when your child applies for a loan or a first card as an adult.
Keep a simple log. Write down the date, the name of anyone you speak with, and any reference number. Save every letter and confirmation. Put copies of what you mailed in the same folder. If you later have to dispute an account, that folder does the talking.
Where to report and what comes next
If a file shows accounts or inquiries you do not recognize, treat it as possible identity theft. The Federal Trade Commission runs IdentityTheft.gov, where you can report identity theft and get a recovery plan. The FTC also publishes advice on protecting a child from identity theft, and the Ohio Attorney General has a consumer newsletter on the same topic. We could not review the full text of either, so read them directly and follow their current instructions.
For the application itself, contact the lender named in the notice. Say that the number belongs to a minor and that you did not authorize the request. Ask for the application to be reviewed, and ask for the response in writing. We found no published rule on how lenders must handle this, so expect to follow up more than once.
If you cannot reach a bureau by the listed method, such as the mail-only route for Equifax, use the contact details on the bureau's own website. Send mail in a way that gives you proof of delivery.
