Technically, no. In the US, you have to be 18 to apply for a credit card in your own name — that’s the CARD Act. And honestly, even at 18, most major issuers want to see independent income before they’ll approve you without a cosigner, so 16-year-olds are locked out of the traditional credit card application process. But “can’t get a credit card” is different from “can’t build credit,” and the distinction matters.
What 16-year-olds can actually do
The one legitimate option that’s available below 18 — and that actually works — is becoming an authorized user on a parent’s or family member’s credit card. Most major card issuers allow authorized users as young as 13, sometimes younger. The primary cardholder adds you to the account; the bank issues a card in your name; and within a billing cycle or two, the account starts appearing on your credit report.
That’s a real credit history posting to a real credit report. The account’s limit, age, and payment record all show up. If the card has been open for years and paid on time, you benefit from that history. FICO doesn’t distinguish between an account you opened yourself and one you were added to — it just sees the account and scores it.
One thing worth knowing: not all cards are equally valuable as authorized user accounts. What the scoring model actually cares about is the credit limit (higher is better for utilization math), the account age, and the payment history. The issuer’s name is irrelevant once the data hits your report. The exception is American Express — since around 2015, Amex reports authorized users with the date they were added as the open date, not the original card open date. So a 12-year-old Amex card won’t give you 12 years of history. Chase, Capital One, and most other issuers don’t have this quirk, which makes them more useful AU cards if account age is part of what you’re chasing.
What does and doesn’t count as “building credit” at 16
Being added to a parent’s credit card builds real credit. Debit cards don’t — they don’t report to the credit bureaus at all, no matter how responsibly you use them. Prepaid cards don’t either. Some apps market themselves as teen credit-building tools, and some actually do report to the bureaus (check carefully), while others are essentially debit with better marketing. The only thing that builds a credit score is accounts that report to Equifax, Experian, and TransUnion.
Understanding revolving utilization matters even as an AU. If you’re added to a card that’s carrying 80% of its limit as a balance, that high utilization is reporting to your file too — it’s not just the good parts that follow you. A card that’s paid down and kept at low utilization is a much better AU card than one that’s maxed out.
What happens when you turn 18
At 18, you can apply for your own credit card. The secured card route is the most realistic for someone without established credit history: you deposit $200–$500, that becomes your limit, and the card reports to the bureaus. A year of on-time payments and low utilization on a secured card builds a foundation. Then you can apply for an unsecured card, get the secured deposit back, and keep growing from there.
If you were an authorized user on a parent’s card from 16 to 18, you arrive at 18 with two years of credit history already posting — which puts you in a meaningfully different position than someone starting from zero at 18. That head start matters when you’re applying for your first car loan or signing a lease.
For people who want to accelerate the process or don’t have access to a family card, authorized user tradelines are a paid option that works the same way — you pay to be added to an established card for three billing cycles, and the account history posts to your report. I sell these at kindoflost.com and also through several brokers. The minimum age requirement varies by tradeline company, so if you’re looking into this for a minor, check the terms specifically.
The honest answer about prepaid and teen debit cards
A lot of products targeting teens — Greenlight, BusyKid, FamZoo — are essentially debit with parental controls and good UX. They’re useful for learning money management habits, which is genuinely valuable. But they don’t build credit in the traditional sense. Some of these apps have added optional credit-reporting features (Step, for example, markets a credit-building component), so it’s worth reading the fine print on whatever product you’re considering. When in doubt, ask: does this account report to Equifax, Experian, and TransUnion? If the answer is no or “only sometimes,” it’s not building a credit score.
You can check the tradelines FAQ for more on how authorized user accounts work, what to look for in a card before being added, and how long the history stays on your report after you’re removed. The CFPB explains authorized user accounts if you want a government-source take on how they work. And if you want to see what’s available on the tradeline side, current listings are here.
No. You must be 18 to apply for a credit card in your own name in the US. Without a parent or cosigner, a 16-year-old has no legal path to their own credit card account.
It depends on the issuer. Chase allows authorized users as young as 13. American Express has no minimum age. Some issuers require the AU to be 16 or 18. There’s no federal minimum, so the policy varies bank by bank.
Yes, if the card has a positive payment history, a decent limit, and low utilization. The account reports to your credit file and the scoring model treats it the same as an account you opened yourself. High utilization or missed payments on the card will also show up on your report, so the card’s payment and utilization history matters.
