Building credit is crucial for your child's financial future, but getting started can feel overwhelming. One of the most straightforward ways to help your child establish a solid credit foundation is by adding them as an authorized user on your existing credit card account.
But here's the key question: How old do they need to be?
The answer varies significantly by credit card issuer, and understanding these requirements can help you make the best decision for your family's financial strategy.
What Is a Credit Card Authorized User?
An authorized user is someone you add to your existing credit card account, giving them their own physical card to make purchases. As the primary cardholder, you remain fully responsible for all charges and payments, but your authorized user benefits from your account's credit history.
This setup creates a win-win situation: your child starts building credit history without the responsibility of managing their own account, while you maintain complete control over spending and payments.
Important note: Even if you don't plan to give your child the physical card, simply adding them as an authorized user can help them establish positive credit history, assuming your account remains in good standing.

Benefits of Adding Your Child as an Authorized User
Credit History Building
Your child can start building positive credit history years before they're eligible for their own card. This head start can be invaluable when they apply for student loans, apartment rentals, or their first credit card.
Financial Education
Having access to a credit card provides real-world experience with financial responsibility. You can teach important concepts like:
- How billing cycles work
- The importance of paying on time
- Understanding credit utilization
- The difference between needs and wants
Emergency Access
If your child faces an emergency when you're not available, having a credit card can provide crucial financial access for unexpected expenses.
Rewards Earning
Every dollar your authorized user spends earns the same rewards as your regular purchases, helping you maximize your credit card rewards.
Potential Drawbacks to Consider
Your Credit Affects Theirs
If your account develops problems—late payments, high balances, or defaults—these negative marks will also impact your child's credit report.
Spending Responsibility
You're legally responsible for all charges made by authorized users, regardless of your agreement with them.
Impact on Future Credit Applications
Authorized user accounts may count toward Chase's 5/24 rule, potentially affecting your child's ability to get certain cards later (though this can often be resolved by calling Chase).
How to Remove an Authorized User
If you need to remove an authorized user, the process is usually simple:
- Online: Log into your account and navigate to authorized user management
- Phone: Call customer service and request removal
- Timeline: The user is typically removed within minutes, but it may take several weeks for the account to stop appearing on their credit report
Pro tip: Request a new card number when removing an authorized user to ensure the old card can't be used.
Alternative Ways to Build Credit
If adding an authorized user isn't the right fit, consider these alternatives:
Secured Credit Cards
Secured cards require a security deposit but function like regular credit cards, helping build credit history.
Student Credit Cards
Once your child turns 18 and is enrolled in college, student credit cards designed for newcomers to credit can be excellent options.
Credit Builder Loans
These specialized loans are designed specifically to help people build credit history through regular, on-time payments.
Best Practices for Success
Set Clear Expectations
Before adding your child as an authorized user, establish clear rules about:
- What purchases are acceptable
- Spending limits
- Consequences for misuse
Monitor Regularly
Check your account frequently to track spending and ensure responsible use. Most card issuers offer real-time spending alerts.
Use It as a Teaching Tool
Turn every purchase into a learning opportunity about budgeting, interest rates, and financial responsibility.
Keep Good Habits
Since your credit behavior directly affects your child's credit report, maintain excellent payment history and low credit utilization.
When to Consider Removal
You should consider removing your child as an authorized user if:
- They're consistently irresponsible with spending
- You're experiencing financial difficulties
- They're ready to establish their own credit account
- They're applying for their own credit cards and need to reduce their account count
Frequently Asked Questions
Can I add my newborn as an authorized user?
While some issuers allow it, there's no benefit to adding very young children since they won't be actively using credit or learning financial responsibility.
Will being an authorized user hurt my child's credit?
Only if your account develops problems. As long as you maintain good credit habits, being an authorized user should help, not hurt, their credit.
Can my child use the card without my permission?
Legally, yes, if they have the physical card. However, you remain responsible for all charges, so clear communication and rules are essential.
How long does it take to build credit as an authorized user?
Your child can start seeing credit history within 1-3 months of being added, assuming the issuer reports to credit bureaus.
The Bottom Line
Adding your child as an authorized user can be an excellent way to help them build credit history and learn financial responsibility. The key is choosing the right credit card issuer based on their age requirements and your family's needs.
Remember that building good credit takes time and consistency. By starting early with responsible habits, you're giving your child a valuable head start on their financial future.
Whether you choose a rewards credit card or a simple cash back option, the most important factor is maintaining excellent payment history and keeping your credit utilization low.
Your child's financial future starts with the decisions you make today. Adding them as an authorized user is just one tool in building their credit foundation, but it's a powerful one when used responsibly.
