Call Capital One's customer service line to cancel your card
The fastest way to close a Capital One credit card is to call their customer service number on the back of your card. A representative will walk you through the cancellation, answer questions about your account, and confirm the closure in writing. The call takes about 10 minutes.
Have your card number ready when you call. Capital One will ask whether you want to close the account or just stop using the card — these are different things. Closing the account means Capital One will not reopen it later; stopping use means the account stays open but inactive. If you want it fully closed, say so clearly.
After you hang up, Capital One will send you a written confirmation by mail. Keep this letter. It proves the account is closed and protects you if a debt collector later claims you still owe money on it.
Key Takeaways
- Call the number on the back of your Capital One card to speak with a representative who can close the account immediately.
- Tell the representative you want to close the account, not just stop using it, if you do not want Capital One to reopen it later.
- Request written confirmation of the closure and keep the letter for your records.
- Pay off any remaining balance before closing, because Capital One will not close an account with an outstanding debt.
- Closing a card can lower your credit score temporarily because it reduces your total available credit, but the effect fades over time.
What happens to your balance when you close the card
If you have a balance on your Capital One card when you call to close it, Capital One will not close the account until you pay it off. You will need to settle what you owe first — either in full or by setting up a payment plan with the representative.
Once the balance is zero, the account can be closed. Capital One will stop charging new interest, but any remaining balance will still accrue interest until it is paid. If you close the account and later realize you cannot pay the full amount, you can reopen it by calling back, though Capital One may not agree to this depending on your situation.
How closing a card affects your credit score
Closing a credit card usually lowers your credit score in the short term. The main reason is that it reduces your available credit — the total amount you can borrow across all your cards. If you had a $5,000 limit on the Capital One card and a $3,000 limit on another card, closing the Capital One card cuts your available credit from $8,000 to $3,000. Credit scoring models see this as riskier, even though you did not actually borrow more.
The score drop is usually temporary. After six to twelve months, the closed account stops affecting your score as much. The bigger long-term factor is whether you keep paying other debts on time. If you do, your score will recover.
If your Capital One card is your oldest account, closing it can also lower your score because credit scoring models reward a longer credit history. In this case, you might consider keeping the card open but unused instead of closing it. You can ask Capital One to stop sending statements if the inactive account bothers you.
Canceling online or by mail if you cannot call
Capital One does not offer a way to close your account through their website or mobile app. You must call customer service. If you cannot make a phone call, you can send a written request by mail to Capital One's customer service address — this address is on your statement or on Capital One's website. Include your account number, card number, and a clear statement that you want to close the account.
Closing by mail takes longer than calling. Capital One typically takes 7 to 10 business days to process a written closure request, and you will not receive confirmation until they mail it back to you. During this time, the account is still open and you can still be charged fees or interest.
If you have a balance on the card, include a check or money order for the full amount with your letter. Do not send cash through the mail.
What to do before you close the card
Before you call Capital One, make sure no automatic payments are still linked to the card. Check any subscriptions, insurance payments, or utility bills that might charge the card monthly. Move those payments to a different card or bank account. If a payment tries to go through after the card is closed, it will be declined and you could miss a payment deadline.
Also check your Capital One account online to see if there are any pending transactions or holds on the card. These can take a few days to clear, and closing the account while they are pending can cause problems. Wait until everything has settled.
If you have Capital One rewards points or cash back that has not been redeemed, use them before closing. Once the account is closed, you may not be able to redeem them, depending on Capital One's policy at the time.
What happens after the account is closed
After Capital One closes your account, the card will no longer work. You can keep the physical card or destroy it — it does not matter. The closed account will stay on your credit report for seven years, but it will be marked as "closed by consumer" rather than "closed by creditor," which looks better to future lenders.
If you later realize you need the card back, you can call Capital One and ask them to reopen it. They may agree, but they are not required to. Reopening is easier if you closed the account in good standing — meaning you paid on time and had no balance — but Capital One will review your account history before deciding.
Frequently Asked Questions
Will closing my Capital One card hurt my credit score?
Yes, but usually only temporarily. Your score may drop by 10 to 50 points in the short term because closing the card reduces your available credit. The effect fades over six to twelve months as long as you keep paying other debts on time. If the Capital One card is your oldest account, the impact may last longer.
Can I close my Capital One card if I still owe money on it?
No. You must pay off the balance first. Capital One will not close an account with an outstanding debt. You can set up a payment plan with the representative if you cannot pay the full amount immediately, but the account will stay open until the balance reaches zero.
What if I want to keep the card open but stop using it?
Tell the representative you want to keep the account open but inactive. Capital One will not close it, and the account will stay on your credit report. You can ask them to stop sending statements if you prefer not to receive mail about an unused card.
How long does it take to close a Capital One card?
If you call, the closure happens immediately and you will receive written confirmation by mail within 7 to 10 business days. If you close by mail, the entire process takes 7 to 10 business days from when Capital One receives your letter.
Can I reopen my Capital One card after closing it?
You can call and ask Capital One to reopen it, but they are not required to agree. Reopening is more likely if you closed the account in good standing with no balance and a history of on-time payments. Capital One will review your account before deciding.
