Can You Have a Credit Score Under 18?

Most minors do not have a credit score because a credit score can only be generated from a credit file, and a credit file is created when an individual is listed on a tradable account that reports to the major bureaus-something that typically requires the person to be at least 18. Since minors cannot legally enter binding credit contracts, they rarely appear on any reporting-eligible account, so there's no data for the scoring models to evaluate.

In the few cases where a minor does show up in a credit file-such as when they are added as an authorized user on a parent's credit card or when a student loan is taken out in their own name after turning 18-the resulting score reflects the activity on that specific account, not a lifelong score built from multiple sources. Consequently, while it's technically possible for a minor to acquire a score under very limited circumstances, the overwhelming majority of teens under 18 simply do not have one because the infrastructure needed to produce a score does not exist for them yet.

Because a credit score is derived from a credit file-a record of borrowing and repayment activity- a person must first have at least one tradable account that reports to the major bureaus. Under U.S. law, most credit products (credit cards, auto loans, mortgages) require the applicant to be at least 18 years old, so minors rarely open accounts in their own name. Without an account that generates reporting data, there is nothing for the bureaus to aggregate, and consequently no credit score is produced.

Even when a minor does appear on an existing account, the effect on their own credit file is limited. Being added as an authorized user can place the primary account's payment history into the minor's file, but many lenders still restrict reporting for users under 18, and some credit bureaus simply ignore the record until the user reaches adulthood. As a result, most minors finish childhood without a credit file at all, which is why a credit score is typically absent until they turn 18 and can legally assume responsibility for a credit product of their own.

A credit score is calculated from the information stored in a person's credit file-a record that tracks borrowing and repayment behavior once an individual has at least one tradable account reported to the major bureaus. The three core pillars that feed the file are payment history (whether bills are paid on time), credit utilization (the ratio of balances to limits), and length of credit history (how long accounts have existed). Secondary factors such as types of credit (installment vs. revolving) and recent inquiries also influence the final number, but they only tweak the score after the primary data are established.

For a teen who already has a credit file, each on-time payment on a student loan, a secured credit card, or even a family member's account where the teen is listed as an authorized user will add positive marks to the file. Conversely, missed payments, maxed-out balances, or frequent hard pulls can drag the score down. A minor who has never been added to a credit file-because most lenders won't issue a product to someone under 18-simply has no score to calculate until an eligible account appears on their record.

A teen's first chance to put a credit file on the record comes as soon as they turn 18, because only adults can be listed as primary account holders in the major reporting systems. Before that age, the only way a minor can appear on a credit file is as an authorized user on someone else's account-typically a parent's credit card-that has already been established and is being reported.

1. Wait until the birthday turns 18 - Once the teen reaches legal adulthood, they can apply for their own credit card, loan, or other revolving account that will generate a credit file.
2. Become an authorized user earlier (optional) - If the parent adds the minor as an authorized user on a well-managed card, the teen's credit file will start to reflect that activity, even though they are still under 18.
3. Open a student or secured credit card after 18 - Many issuers offer cards designed for first-time borrowers; a secured card requires a cash deposit, while a student card may have lower limits but still reports to the bureaus.

These steps outline the typical pathways: waiting for adulthood to hold an account in their own name, or using an authorized-user arrangement beforehand to seed a credit file.

Being added as an authorized user on a parent's credit card is the most common way a teen can start a credit file before turning 18. The account remains legally owned by the primary holder, but the credit bureaus treat the authorized-user status as a separate entry that can later generate a score once the teen reaches adulthood and meets the age requirements of the scoring model.

• The primary holder must add the teen's name and Social Security number (or ITIN) to the account.
• The credit card issuer reports the authorized-user activity to the major bureaus; most do, but a few still omit it.
• The teen's credit file will reflect the account's payment history, balance utilization and overall age, just like any other account.
• No credit limit or spending power is required for the teen to benefit-only the presence of the account on their file.
• If the primary holder misses payments or carries high balances, those negatives also appear on the teen's file.

When the teen turns 18 and qualifies for a consumer-credit score, the authorized-user line can instantly produce a measurable credit score based on the existing history. This early exposure can give the teen a head start, provided the primary holder maintains good habits and monitors the shared account for errors.

A parent's credit history does not automatically extend into a minor's credit file. Credit bureaus treat each consumer as an individual record, and because a minor cannot legally enter binding contracts, the system simply has no space to attach the parent's score to the child's profile. Consequently, a teen under 18 will not inherit any of the numeric value that a parent enjoys; the parent's score remains confined to the adult's own credit file and cannot be "shared" in the way a bank account balance can be.

However, parents can lay the groundwork for a future credit file by giving the teen limited, supervised exposure to credit activity. Adding the minor as an authorized user on a well-managed credit card places the account's payment history onto the teen's file once the child turns 18, provided the issuer reports authorized users to the bureaus. Likewise, opening a joint checking or savings account-and consistently paying any related bills on time-demonstrates financial responsibility that lenders may consider when the teen eventually applies for their own credit. These steps don't boost the minor's score today, but they create a clean slate and a positive trail that can translate into a stronger credit file once the teen reaches adulthood.

When you turn 18, your credit file is still empty because the system only begins tracking credit activity once you open an account that reports to the bureaus. That means there is no credit score to look at, and lenders will treat you as a "credit-invisible" applicant until you generate enough data-usually by using a revolving or installment product responsibly for several months.

Because the file is blank, many creditors will rely on alternative indicators such as your income, employment history, or a co-signer's credit profile. Some may offer a secured credit card or a starter loan that requires a modest deposit, which instantly creates a tradable record. Until those accounts appear on your file, any credit decision will be based on the information you provide rather than a numerical score.

If you want a score sooner rather than later, the quickest route is to open a product that reports from day one. A secured card, a student loan in your name, or an authorized-user arrangement where the primary holder adds you (and the bureau records the activity under your Social Security number) will generate the first entries in your credit file. Once those entries accumulate, the scoring models can calculate a credit score and you'll move out of the "no-score" zone.

If you're a minor thinking about a credit file, the first step is to lay a solid foundation before you can even qualify for a score-most minors won't have one until they turn 18, but you can position yourself for a smooth transition by taking actions that demonstrate responsibility and prepare the necessary paperwork.

• Open a joint checking or savings account with a parent or guardian to practice managing balances and avoiding overdrafts.
• Ask a parent to add you as an authorized user on an existing credit card that has a low utilization rate and a long, positive payment history; this won't give you your own credit file, but it can familiarize you with how credit works and may appear on your future report once you're eligible.
• Keep a record of on-time payments for any recurring bills (phone, utilities, streaming services) that are in your name; some newer reporting models allow these histories to seed a credit file when you turn 18.
• Start building a modest credit "profile" by obtaining a secured student loan or small personal loan once you're legally an adult; having documentation of stable income (part-time job) will make the application easier.

These steps don't generate a credit score today, but they give you the habits, relationships, and documentation that lenders look for once you become eligible to open your own accounts.

A common misconception is that every minor automatically gets a credit score the moment they turn 16 or open a bank account. In reality, a credit score only appears when a credit file contains at least one tradable account-such as a credit card, auto loan, or student loan-that reports activity to the bureaus. Since most minors cannot legally sign contracts, they rarely have such accounts in their own name, so the bureaus have nothing to score. Simply having a checking or savings account, or being listed on a parent's utility bill, does not generate a credit file and therefore does not produce a score.

Another myth is that being an authorized user on a parent's credit card instantly boosts a minor's credit standing. While authorized-user status can add the primary holder's payment history to the minor's file, it only does so if the creditor actually reports authorized users to the bureaus-a practice that varies by issuer. Even then, the impact is limited: the minor's file will reflect the account's activity, but no independent credit score will be calculated until the minor reaches 18 and can apply for credit in their own name. Consequently, many teens assume they are "building credit" simply by hanging onto a card, when in fact the credit file may remain dormant until adulthood.
