Student credit cards: the under-21 rule and how to build credit in college
Edited by Moe Ameen · Published
If you're under 21, a card issuer can open a credit card account for you only if you show an independent ability to make the minimum payments or have a cosigner who is 21 or older. That's the CARD Act rule in Regulation Z. Issuers also can't offer college students free items to apply on or near campus. Once you have a card, paying on time matters most: payment history is 35% of a FICO Score.
Key takeaways
- Under 21, you need your own income or assets, or a cosigner aged 21 or older.
- Only income you have yourself counts. A parent paying your bills directly doesn't.
- Issuers can't hand out free items to get students to apply on campus, within 1,000 feet of it, or at school events.
- Being an authorized user can add an account to your report, but only if the issuer reports it.
- Payment history is 35% of a FICO Score and amounts owed are 30%.
Can you get a credit card under 21?
Yes, with a written application and either your own ability to make the minimum payments or a cosigner aged 21 or older.
Regulation Z bars a card issuer from opening an account for someone under 21 unless the application shows an independent ability to make the required minimum payments, or a cosigner, guarantor or joint applicant who is 21 or older and able to pay signs on to be liable for the debt [1]. The CFPB puts it plainly: card companies generally can't issue cards to anyone under 21 unless one of those two things is true [2].
Cosigning is a real commitment. The cosigner agrees in writing to be responsible for the debt [1], so a missed payment is their problem as well as yours.
What income counts for a student credit card application?
Your own current or expected income or assets. Money a parent or roommate has, or pays toward your bills directly, generally doesn't count.
The official commentary says an issuer looking at an under-21 applicant can only consider the applicant's own income or assets, not income they merely have a reasonable expectation of access to [3]. The income of household members or other people who aren't liable on the account doesn't count, and an issuer can't rely only on an answer to a "household income" question [3].
There are two exceptions in the commentary. Income someone else regularly deposits into a joint account with you can count, and so can money they regularly transfer into an account in your name [3]. Money they spend on your expenses directly doesn't [3].
Example: wages from a part-time campus job count. A parent paying your rent straight to the landlord doesn't. A parent who moves money into your own checking account every month can.
Can a student card's credit limit go up before you turn 21?
Only if you can show independent ability to pay at the time, or a cosigner aged 21 or older agrees in writing to cover the increase.
If your account was opened on your own income, the issuer can't raise the limit before you turn 21 unless you show independent ability to pay at that point, or a person 21 or older agrees in writing to take on the debt [1]. If a cosigner opened the account with you, that cosigner has to agree in writing to the increase [1].
What are the rules for credit card marketing on campus?
Issuers can't offer college students a tangible item to apply on campus, near campus or at a school event. Schools must disclose card agreements.
Regulation Z bars card issuers from offering a college student any tangible item to apply for or open a card if the offer is made on campus, near campus or at an event sponsored by or related to the school [4]. Near campus means within 1,000 feet of the campus border as the school defines it [4].
Colleges have to publicly disclose any agreement they make with a card issuer to market credit cards, and issuers with college card agreements have to report on them to the CFPB every year [4]. So if your school's name is on a card, the deal behind it should be public.
How do you build credit as a student?
Pay every bill on time and keep your card balances low. Payment history is 35% of a FICO Score and amounts owed are 30%.
- Pay on time, every time Payment history is the largest factor in a FICO Score, at 35% [5]. The CFPB says paying on time, every time, helps build a strong credit history [6].
- Keep balances low Amounts owed make up 30% [5]. Use the credit utilization calculator to see where your balance puts you.
- Let the account age Length of credit history is 15% of a FICO Score [5], so an account you open as a student keeps counting for years.
- Consider a secured card With a secured card you put down a deposit, for example $500, and your spending limit is based on it [6].
What should students watch for with a first credit card?
Late payments, which cost a fee and can reach your credit report at 30 days, a penalty APR at 60 days late, and cash advances, which charge interest from day one.
- A minimum payment more than 60 days late lets the issuer raise your APR, after notice [8]. See what happens if you miss a payment.
- Cash advances cost a fee and start charging interest right away. See credit card cash advances.
- Fees for late payments, foreign purchases and more are all in the card's pricing table. See credit card fees explained.

Routes to a first card under 21, and the rule behind each
| Route | What the issuer needs | Watch for |
|---|---|---|
| Your own card, own income | Your own income or assets covering the minimum payments [1] [3] | Limit increases before 21 need fresh proof of income or a cosigner [1] |
| Your own card, with a cosigner | A cosigner 21 or older who can pay and signs on to be liable [1] | The cosigner owes the debt if you don't pay [1] |
| Authorized user on someone's card | The cardholder adds you to their account | Only helps if the issuer reports it; their late payments can count against you [7] |
The difference is whose risk it is. On your own income, the debt is yours alone. A cosigner shares it with you. As an authorized user you take on part of someone else's record, late payments included.
Is this right for you?
Best for
- Students under 21 working out whether they can get a card and how.
- Parents deciding between cosigning and adding a child as an authorized user.
Not ideal for
- Choosing a specific student card. Each issuer's own pages set its terms.
- Applicants 21 or older. The independent-income rule here only applies under 21.
Frequently asked questions
Can I get a credit card at 18 with no job?
Only with a cosigner 21 or older, unless you have other income or assets of your own. Under 21, an issuer needs your independent ability to pay or a cosigner [1].
Does my parents' income count on a student card application?
Generally no, unless they regularly deposit it into a joint account with you or transfer it into an account in your name [3].
Can credit card companies give out free stuff on campus?
No. Issuers can't offer college students tangible items to apply on campus, within 1,000 feet of it, or at school events [4].
Does being an authorized user build credit?
It can, if the issuer reports authorized users to the bureaus. Many major issuers do, but they don't have to [7].
What matters most for a student's credit score?
Paying on time. Payment history is 35% of a FICO Score [5].
