Most people do not consider credit until their child turns 18 and needs a first card. By then, years of potential history sit unused. The solution is to start the process earlier, and parents may be surprised by how much is possible before their child reaches adulthood.
An expert puts it plainly: waiting until credit is urgently needed is the wrong approach. The longer an account has been established, the stronger the foundation when it matters most. Parents who understand this can give their children a meaningful head start.
Why credit history length matters
A solid credit score simplifies many adult milestones. Whether renting housing, landing certain jobs or accessing credit products, history influences outcomes.
FICO allocates 15% of the total score to credit history, looking specifically at how long each account has remained open. No minimum account age exists as a hard requirement, but maintaining accounts for extended periods strengthens the profile. Starting at 15 or 16 means a child will have real history before they need to rely on it independently.
Ways minors can establish credit history
- Added as an authorized user on a parent's credit account
- Included on a joint account opened in the minor's name
- Victim of identity theft where someone opened accounts using their information
- Credit bureau error that mistakenly created a profile in their name
The final two scenarios are unintended. The first two represent intentional steps parents can take.
Experts note that adding a child as an authorized user is one of the simplest methods. The parent's card activity appears on the child's credit file, essentially transferring positive payment behavior and account age.
When can parents start?
Issuers set their own policies for authorized user minimum ages. Some allow addition immediately, while others impose age restrictions. American Express permits authorized users from age 13. US Bank sets the minimum at 16. Other issuers have no stated minimum at all.
While technically possible to add a child at birth with certain institutions, experts suggest waiting until the child can grasp credit concepts. Around 15 or 16 tends to be a practical starting point, allowing parents to teach responsible usage alongside the technical benefit of building history.
Who should care
| Situation | Recommended action |
|---|---|
| You maintain clean credit with consistent on-time payments | Consider adding your child as authorized user |
| Your child is under 16 and you want maximum runway | Earlier addition compounds history over more years |
| You carry high balances or have missed payments | Avoid this strategy; negative patterns transfer |
| Your child is already over 18 | Explore secured cards instead |
Important considerations
The account selected matters significantly. Since the authorized user's report reflects the primary account holder's behavior, payment history, credit limits and balance levels all appear on the child's file. Experts recommend using the Social Security number during enrollment to ensure proper reporting.
One industry observer emphasizes that starting sooner creates advantages. "A key factor in determining credit is the length of credit history, so the sooner you start, the better," said Ben Arbov, founder and CEO of Greatest Gift, a financial gifting platform focused on children's long-term savings.
For young adults past 18 who lack established credit, secured cards present another option. Parents can assist with the initial deposit, and the cardholder builds habits within a set limit, reducing risk while establishing positive patterns.
Practical steps parents can take
- Select the card with the longest clean payment record and lowest balance-to-limit ratio
- Enroll using the child's Social Security number for accurate reporting
- Begin around ages 15 or 16 when the child can understand responsible usage
- Designate the card for planned purchases to enable teaching moments
- Once the child reaches 18, a secured card can provide a structured next phase
Key takeaways
- Credit history represents 15% of the FICO calculation; longer histories strengthen profiles.
- Authorized user status from ages 13 to 16 builds substantial history before adulthood.
- Only use accounts with clean payment records; negative activity transfers to the child's report.
- Experts recommend ages 15 or 16 as a practical starting point for most families.
- For those already past 18, secured cards offer a structured path to building credit.
Frequently asked questions

It depends on the specific issuer. American Express permits authorized users from age 13, US Bank from age 16, and some institutions set no minimum.

Yes. Account history appears on the child's credit report, establishing credit years before they would otherwise be eligible.
What happens if the parent's account has late payments?
Late payment activity on the parent's account appears on the child's report as well. This strategy only works with consistently clean payment records.
Is adding a child as an authorized user a legitimate approach?
Yes. It is a widely recognized method for jumpstarting credit before age 18. Experts recommend using the child's Social Security number during setup to ensure proper reporting.
