How to Add Your Child as an Authorized User (Step-by-Step)

When you add someone as an authorized user on your credit card, you're giving them a place on your account. The card issuer begins reporting that account's activity to the credit bureaus in their name — not just yours.

For a child, this means they can start building a credit history before they're old enough to open a single account on their own. They don't need to apply for anything. There's no credit check on them. And you stay in full control of the account at all times.

It's one of the most powerful and underused tools in personal finance — and most parents have never heard of it.

Not all cards are created equal for this purpose. Before you add your child, pick the right account.

For the bigger-picture strategy of building your child's credit before 18, the card you pick matters as much as the decision to add them. The ideal card has all four of these:

A long history — the older the account the better. When your child is added, that entire history appears on their credit file. A card you've had for seven years is far more valuable than one you opened last year.

Low utilization — the balance should be well under 30% of the credit limit, and ideally under 10%. High utilization hurts your child's score just as much as it hurts yours.

Perfect payment history — not a single late payment. One missed payment on the account will appear on your child's credit report too.

Reports to all three bureaus — confirm your issuer reports authorized user activity to Experian, Equifax, and TransUnion. Most major issuers do, but it's worth a quick call to verify.

If you have multiple cards, choose the one that's oldest, has the lowest balance relative to its limit, and has the cleanest payment record. That's the one that will do the most for your child's credit file.

There is no federal law setting a minimum age for authorized users. Each card issuer sets its own policy:

No minimum age: Chase, Bank of America, Citi, Discover, Wells Fargo Minimum age 13: American Express, Capital One, Barclays Minimum age 16: Some credit unions and smaller issuers — check your specific card's policy

If your child is under 13 and you have an American Express or Capital One card, use a different card for this strategy. If you only have cards with age minimums, Chase and Citi are easy to get and have no age floor for authorized users.

The process takes about five minutes and can be done online, through your card's app, or by calling the number on the back of your card.

Online or in-app: Log into your credit card account. Find "Account Management" or "Authorized Users" — the exact label varies by issuer. Click "Add authorized user." Enter your child's name and date of birth. Some issuers will ask for their Social Security number — this is optional at most issuers and primarily used to ensure the account gets reported to their credit file correctly. If you provide it, the bureau matching is more reliable. If you prefer not to, most issuers will still add them. Submit. A card in your child's name will arrive by mail in 7–10 days.

By phone: Call the number on the back of your card and tell the representative you want to add a minor as an authorized user. Have your child's full name, date of birth, and Social Security number ready. The representative will confirm whether they report authorized user activity to the bureaus and complete the addition while you're on the call.

No. You can add your child as an authorized user, keep the physical card yourself, and they still receive the credit-building benefit. Many parents do exactly this — particularly for younger children — and remove the card from the equation entirely until the child is ready for that responsibility.

If you do give them the card, set clear expectations upfront: what it can be used for, how much they can spend, and who makes the payments.

Within one to two billing cycles of being added, the account will appear on your child's credit report. If they had no credit file before, one is now created. If a file already existed, this account joins it.

What shows up on their report: The account opening date — which will be the original date you opened the card, not the date they were added. This is the key benefit. A child added at 16 to a card opened in 2015 gets eleven years of history on their file. Your payment history on that card — every on-time payment, and any late payments. The current balance and credit limit — which affects their utilization ratio. The account type — revolving credit, which is the most important account type for building a score.

Within a few months of being added, your child will likely have a credit score for the first time. It won't be their highest possible score — authorized user status alone isn't as powerful as accounts in their own name — but it's a real starting point that makes the transition to independent credit at 18 significantly easier.

About 60 days after adding your child, check whether their credit file has been created — this is also a good moment to scan for any unfamiliar accounts, since child identity theft often goes undetected until the child is older. You can do this through AnnualCreditReport.com for children 14 and older. For younger children, you'll need to contact each bureau directly by mail and request a manual search.

If a credit report exists and shows the account, the strategy is working. If the account isn't appearing, the most likely reason is that your issuer doesn't report authorized user activity — confirm this with a quick call and consider switching to a card that does.

Adding them to a card with a high balance. High utilization hurts their score. Pay down the balance first, or use a different card.

Adding them and then missing a payment. Set up autopay on the card the moment you decide to use it for this strategy. One late payment will show on both your report and theirs.

Assuming any card works. Not every issuer reports authorized users to the bureaus. Verify before you add them.

Removing them too soon. Once you remove your child as an authorized user, that account's history disappears from their credit file. Keep them on until they have enough accounts in their own name — typically two or three accounts with at least 12 months of history each — before removing the authorized user relationship.

Adding them to a joint account instead. This is different from authorized user status. Joint accounts make your child legally responsible for the debt. Authorized user status does not. Keep them separate.

There's no rush to remove your child as an authorized user once they turn 18 and start building their own credit. Many parents keep the relationship active for years — it provides a safety net and continues to contribute positively to the credit file.

The right time to remove them is when their independent credit history is strong enough to stand on its own. A general rule: once they have three or more accounts in their own name, each with at least 12 months of clean payment history, the authorized user account matters less. At that point removing it will have minimal impact on their score.
