Yes, you can have a credit score under 18, but it isn’t automatic and it isn’t common. A minor usually builds a credit file by being added as an authorized user on a parent’s credit card; once enough account history is reported in the child’s name, a score can be generated. A file can also appear without anyone setting it up, and when that happens the cause is almost always identity theft.
Why Most People Under 18 Don’t Have a Score
Under common law principles followed in every state, a contract signed by a minor is voidable, meaning the minor can walk away from the deal without penalty. Because lenders cannot reliably enforce a debt agreement against someone under 18, they almost never extend independent credit to minors. No borrowing activity means no payment history for the credit bureaus to track, and no score.
The Truth in Lending Act adds a second hurdle specifically for credit cards. Anyone under 21 has to either show independent ability to make payments or have a co-signer who is at least 21.1Office of the Law Revision Counsel. 15 U.S.C. 1637 – Open End Consumer Credit Plans In practice, that closes off independent card ownership for most teenagers.
The Authorized User Route
Being added as an authorized user on a parent’s or guardian’s credit card is the most common way a minor develops credit. The child gets a card tied to the adult’s account, and the adult stays responsible for every charge. Many issuers set no minimum age at all; others require the authorized user to be at least 13.2Consumer Financial Protection Bureau. Can a Credit Card Company Consider My Age When Deciding to Lend Me a Card?
When the issuer reports authorized user data to the bureaus, the account’s full history, including its age, credit limit, and payment record, is added to the child’s credit file. Over time, that reported history can produce a score. Not every issuer reports authorized user activity to all three bureaus, though. Confirm the issuer’s reporting practice before assuming the arrangement will actually build the child’s credit.
Teen Credit Products That Require a Co-Signer
A small number of institutions offer credit products aimed at teenagers, such as student credit cards for applicants as young as 15 or credit builder loans for those 16 and up. These products always require a parent or guardian to co-sign, which satisfies the legal requirement for a binding contract that a minor cannot meet alone. Payments are reported under both names, so a track record accrues on the child’s file before adulthood.
Co-signing is not risk-free for the adult. The co-signer is equally responsible for the debt, and missed payments show up on both credit reports. Late payments stay on a report for seven years and can make it harder for the co-signer to qualify for new credit during that time.
When a Credit File Signals Fraud, Not Credit-Building
If no one has deliberately set up credit for a child and a file already exists, the cause is almost always identity theft. Criminals target children’s Social Security numbers because the fraud often goes undetected for years. No one checks a five-year-old’s credit report. A thief may combine a child’s real Social Security number with a fake name and date of birth to create a synthetic identity, then open accounts under it. By the time the child applies for their first legitimate credit product, the file may already carry delinquencies and collections.
Files can also appear through data errors, such as a lender merging a minor’s information with a relative who shares a similar name.
Warning signs that a child already has a file worth checking:
- Pre-approved credit offers arriving in the child’s name rather than addressed to “current resident.”
- Being told a bank account or college savings plan can’t be opened because one already exists, or being denied because of poor credit tied to the child’s Social Security number.
- The child being denied health coverage, nutrition assistance, or other benefits because their Social Security number is already linked to an active benefits account.
- An IRS letter about unreported income or taxes owed under the child’s Social Security number.

How to Check Whether a Minor Has a Credit File
A parent or legal guardian has to contact Equifax, Experian, and TransUnion separately. Each bureau has its own process, and a file may exist at one but not the others.4Consumer Financial Protection Bureau. How Do I Check to See if a Child Has a Credit Report?
All three bureaus want similar documentation:
- A copy of the child’s birth certificate, showing the parent-child relationship.
- A copy of the child’s Social Security card.
- A copy of the parent’s government-issued ID.
- Proof of address, such as a utility bill or bank statement, matching the address on the parent’s ID.
- If you are not named on the birth certificate, a court order or other proof of guardianship.
TransUnion offers an online Child Identity Theft Inquiry form for checking whether a file exists.5TransUnion.

If a file exists, the bureau sends back a full credit report listing accounts and inquiries. If none is found, you’ll receive a letter confirming that no record is associated with the child’s Social Security number.8AnnualCreditReport.com. Requesting Reports in Special Situations
Freezing a Minor’s Credit File
A credit freeze blocks anyone from opening new accounts in a child’s name. Federal law gives parents and legal guardians the right to place a free freeze on any child under 16. Minors who are 16 or 17 can place and remove a freeze themselves.9Office of the Law Revision Counsel. 15 U.S.C. 1681c-1 – Identity Theft Prevention; Fraud Alerts
If a bureau does not already have a file on the child, it must create one for the sole purpose of freezing it. That record cannot be used to evaluate the child’s creditworthiness. The freeze stays on until the parent, or the child once old enough, asks for it to be lifted. The documentation is the same as for checking a report, and the request must go to each of the three bureaus separately.3TransUnion. Child Identity Theft
If the Check Turns Up Fraudulent Accounts
The FTC recommends three steps when a child’s credit report shows accounts they never opened:10Federal Trade Commission. How To Protect Your Child From Identity Theft
- Contact the fraud department at every company where an account was opened, ask them to close it, and request written confirmation that your child is not responsible for the debt.
- Dispute the accounts with all three credit bureaus and include a copy of the birth certificate to prove the account holder is a minor.
- File a report at IdentityTheft.gov to generate an official Identity Theft Report you can use with creditors and bureaus.
Once the fraudulent accounts are removed, place a freeze on the child’s file at all three bureaus. Keep copies of every letter, dispute form, and confirmation. There is no cost to place or lift the freeze, and it remains in effect until you or your child asks for it to come off.
