You almost certainly do not have a credit score at 17. Credit scores are built from a credit report, and most 17-year-olds have no report because federal law and basic contract law keep minors from opening credit accounts on their own. The usual way to start a file before 18 is to be added as an authorized user on a parent’s or guardian’s credit card.
Why 17-Year-Olds Usually Have No Score
FICO and VantageScore both run from 300 to 850, and both pull their data from the credit reports held by Equifax, Experian, and TransUnion. If none of those bureaus has a file on you, there is nothing to score. No loan, no credit card, no reported account means no report, and no report means no number.
Two rules keep most minors out of that system. The first is contract law: people under 18 generally lack the legal capacity to enter binding contracts, and a minor who signs one can later choose to walk away. Because that debt is voidable at the minor’s option, lenders rarely extend credit to anyone under 18.
The second is the Credit CARD Act of 2009. No one under 21 can open a credit card account without either a cosigner who is at least 21 or enough independent income to cover the minimum payments.1Office of the Law Revision Counsel. 15 USC 1637 – Open End Consumer Credit Plans Between the two rules, a 17-year-old effectively cannot get credit in their own name.
When a 17-Year-Old Might Already Have a Report
Some minors do turn out to have a credit file. The Consumer Financial Protection Bureau lists three ways it happens:2Consumer Financial Protection Bureau. How Do I Check to See if a Child Has a Credit Report
- A parent or guardian added the minor as an authorized user on a credit card, and that account’s history is now reporting under the minor’s Social Security number.
- Someone used the minor’s Social Security number to open accounts fraudulently. Children are common targets because their numbers are clean and the theft can go undetected for years.
- A bureau accidentally merged the minor’s information with a relative who has a similar name, most often a parent and child sharing a first and last name.
Only the first case is helpful. If a report exists at 17 and no one has added you as an authorized user, that is a signal to check for identity theft or a mixed file and to contact each bureau to dispute what is there. Federal law also lets a parent or guardian place a free security freeze on a child’s file, and minors between 16 and 17 can request a freeze on their own using the process available to adults.3Office of the Law Revision Counsel. 15 USC 1681c-1 – Identity Theft Prevention Fraud Alerts
Starting a Credit File as an Authorized User
Being added as an authorized user on a parent’s or guardian’s credit card is the practical route to credit before 18. Once you are on the account, its history, including payments and balance, is added to your credit report.2Consumer Financial Protection Bureau. How Do I Check to See if a Child Has a Credit Report
The primary cardholder handles the request. They call the issuer or use the bank’s website or app and provide your full legal name, date of birth, and Social Security number. Some issuers require authorized users to be at least 13, others 15, and some set no age minimum. There is no credit check on the authorized user.
You do not need to carry the card or ever use it. Being listed on the account is enough for the history to show up on your report. The catch is that the strategy inherits the cardholder’s habits. On-time payments and low balances help; missed payments and high utilization hurt.
Picking the Right Account
Not every card is worth being added to. Look for one with a long record of on-time payments, a low balance relative to the credit limit, and several years of age. Length of credit history feeds into the score, so a card opened a decade ago gives a stronger foundation than a card opened last month.
What Can Go Wrong
Your credit history is tied to the cardholder’s behavior on that specific account. Missed payments, high balances, or a default will appear on your report too. You are not liable for the debt itself, only the primary cardholder is. If the account starts dragging your credit down, you can ask the issuer to remove you and then ask the bureau to delete the account from your report.
How Long Until a Score Appears
Being added as an authorized user does not produce a score overnight, and the wait depends on which scoring model a lender pulls.
FICO, the more widely used model, needs at least one account that has been open for six months or more and at least one account that has reported to a bureau within the past six months.4myFICO. What Are the Minimum Requirements for a FICO Score If you are added to a card that has been open for years, its full history typically comes over to your report and you may meet that bar right away. On a new account, you wait the full six months.
VantageScore can generate a score with as little as one month of history. VantageScore 4.0 has a specific scoring band for thin-file and young consumers with two or fewer accounts or no account older than six months, so an authorized user can see a VantageScore well before a FICO score exists.
Issuers report to the bureaus roughly once a month, usually on the statement date, so authorized user activity generally appears on your report within one to two billing cycles.
What Changes at 18
Turning 18 removes the contract-law barrier, but the CARD Act still applies until 21. Between 18 and 20 you can open a credit card only with a cosigner who is at least 21 or with proof of enough independent income to cover the minimum payments.5Consumer Financial Protection Bureau. Regulation Z 1026.51 – Ability to Pay
A secured credit card is one of the easier ways in. You put down a refundable security deposit, often $200 to $300, and that deposit becomes your credit limit. The card works like any other and reports your payments to the bureaus each month.
Other options once you are 18:
- Student credit cards, designed for applicants with limited history, often with lower limits and no security deposit.
- Credit-builder loans, where you make fixed monthly payments into a savings account, the lender reports those payments to the bureaus, and you receive the funds at the end of the term.
- Continuing as an authorized user on a family member’s card while you build accounts in your own name.
Accounts in your own name build a stronger, more independent profile than authorized user status alone. A mix of account types and a consistent record of on-time payments are the two biggest levers on your score over time.
