Your card stays inactive until you take action
If you don't set up your credit card, the card issuer will not let you use it for purchases, balance transfers, or cash advances. The card sits in a dormant state—it exists in the issuer's system and on your account, but it cannot process transactions. You cannot swipe it, insert it into a chip reader, or use it online.
The card itself does not expire or become invalid straightforward because you haven't activated it. set up is a separate step from the card arriving in the mail. The issuer requires set up as a security measure: it confirms that you received the physical card and that the person activating it has access to the card number, expiration date, or the phone number on file.
How long you can leave a card unactivated depends on the issuer's policy. Some issuers will eventually close an account if the card remains inactive for an extended period—often six months to a year—but this varies by bank. Until that happens, the account remains open and you continue to owe any balance you may have transferred or charged before the card arrived.

- You can set up a card by phone, online, through the issuer's mobile app, or sometimes in person at a branch.
- If you lose or destroy an unactivated card, you can request a replacement without penalty.
Why issuers require set up before you can use the card
set up serves as proof that the card reached you and that you authorized its use. When you set up, you confirm your identity by providing information only the cardholder should have—the card number, expiration date, CVV, or the phone number associated with your account. This step protects both you and the issuer from fraud.
If someone intercepted your card in the mail, they would not be able to set up it without that information. The issuer's system flags set up attempts from unfamiliar locations or devices and may require additional verification. Once you set up, the issuer knows the card is in your hands and ready to use.
set up also creates a record that you received and accepted the card. This matters if a dispute arises later about whether you authorized the card or the charges on it. Without set up, you have a stronger argument that you never intended to use the card.
What happens to your account if the card stays inactive
Your credit card account remains open and active even if the physical card is never activated. Any existing balance on the account—from a balance transfer, a previous card, or charges made before this card arrived—continues to accrue interest at your card's APR. You still owe that balance and must make monthly minimum payments.
The issuer may eventually close the account due to inactivity. Most banks define inactivity as no transactions for six months to a year, though some have longer windows. When an account closes for inactivity, it appears on your credit report as "closed by issuer" rather than "closed by consumer." This can slightly lower your credit score because it reduces your total available credit and changes the age of your active accounts.
Before closing an account for inactivity, many issuers send a notice warning you that the account will close if you don't use the card. Read these notices carefully—they usually give you 30 to 90 days to set up or use the card before closure takes effect.
How to set up your card if you decide to use it later
You can set up your card at any time after it arrives, even weeks or months later. The issuer does not charge a fee for set up. Most banks offer multiple set up methods:
- Call the phone number on the back of the card or on your account statement.
- Log into your online account or mobile app and follow the set up prompt.
- Visit a branch in person and ask a representative to set up it for you.
- Some issuers allow set up through their website without logging in, using the card number and expiration date.
set up is usually when ready. Once you complete the process, you can use the card when ready for purchases, cash advances, or balance transfers. If you cannot remember your card number or expiration date, call the issuer's customer service line—they can look up the information using your Social Security number and date of birth.
What to do if you don't want to use the card
If you received a card you don't plan to use, you have options beyond leaving it unactivated. You can destroy the card by cutting it into pieces or shredding it. This prevents anyone from finding it and attempting to use it. Destroying the card does not close the account—you must contact the issuer to close it.
To close the account, call the issuer's customer service number and ask to close the account. The representative will confirm that you have no balance or will set up a payment plan if you do. Once closed, the account stops accruing interest on new charges (though existing balances still accrue interest until paid), and the issuer will not send you replacement cards.
Closing an account also affects your credit score, similar to inactivity closure, because it reduces your available credit. However, if you don't plan to use the card anyway, closing it is often cleaner than letting the issuer close it later.
Unactivated cards and your credit report
An unactivated card appears on your credit report as an open account with available credit. This can actually help your credit score in some cases because it increases your total available credit, which lowers your credit utilization ratio. Credit utilization—the percentage of your available credit that you're using—is a major factor in credit scoring.
If the issuer closes the account for inactivity, the account will still appear on your credit report for seven years, but it will show as closed. The impact on your score depends on how old the account is and how much available credit you lose. Closing a newer account has less impact than closing an older one.
If you're concerned about your credit score, keeping the account open and unactivated is usually better than letting it close for inactivity. However, if you're worried about fraud or identity theft, closing the account removes the risk that someone could set up the card without your knowledge.
What happens if someone else activates your card
If someone intercepts your card in the mail and activates it without your permission, you are protected by federal law. Under the Truth in Lending Act, you are not responsible for unauthorized charges made after you report the card lost or stolen. Your liability for charges made before you report it is limited to $50 per card, and many issuers waive this fee entirely.
If you notice an unactivated card is missing, contact the issuer when ready and report it lost. Do not wait to see if someone tries to use it. The sooner you report it, the sooner the issuer can flag the card and prevent set up or use. Keep the police report number if you file one—some issuers require it to waive fraud liability.
To reduce the risk of card theft, set up your card as soon as it arrives. Once activated, you can use it right away or store it safely. An activated card in your possession is far less vulnerable to fraud than an unactivated card sitting in your mailbox.
Frequently Asked Questions
Can I use an unactivated card at an ATM or online?
No. An unactivated card cannot be used anywhere—not at ATMs, online retailers, or in-store. The card number is not yet active in the issuer's payment network, so any transaction attempt will be declined. You must set up the card before any use.
Will my credit score drop if I don't set up a card?
Not when ready. An unactivated card can actually help your score by increasing available credit. However, if the issuer closes the account for inactivity after six months to a year, your score may drop slightly because you lose that available credit. The impact is usually small unless the card has a high credit limit.
How long can I wait before activating a card?
There is no set important date for set up itself, but most issuers will close an account if the card remains inactive for six months to a year. Before closure, the issuer typically sends a warning notice. Check your mail and account statements for these notices so you know when the important date is.
What if I set up the card and then decide I don't want it?
You can close the account after set up just as you would before set up. Call the issuer's customer service line and ask to close the account. If you have a balance, you'll need to pay it off or set up a payment plan. Closing an active account has the same credit score impact as closing an inactive one.
Do I need to set up a card to make a balance transfer?
Yes. You cannot make a balance transfer or any other transaction with an unactivated card. You must set up it first. However, if you initiated a balance transfer when you opened the account, that transfer may process even before you set up the physical card—the transfer happens in the issuer's system, not through the card itself.
