Activating your new Capital One credit card is quick, straightforward, and can be done in just a few minutes. Whether you prefer to do it online, through the Capital One mobile app, or over the phone, you'll be ready to make purchases as soon as activation is complete. Choose whichever method works best for you below.

<Tip>
  Before you begin, have your card handy. You may be asked to verify your identity using the 3-digit CVV printed on the back of the card (or the 4-digit code on the front, if you have an Amex-network card).

      <Step title="Verify your identity">
        Confirm your card details when prompted — such as your card number or the CVV — to verify that the card is in your possession.
      </Step>

      <Step title="Confirm activation">
        Follow the on-screen instructions to complete activation. You'll see a confirmation message once your card is active and ready to use.

  <Tab title="By Phone">
    Prefer to speak with someone directly? You can activate your card over the phone in just a couple of minutes.

    ## Phone Activation

    Look at the **back of your new Capital One card** — there's a sticker or printed phone number specifically for new card activation. Call that number and follow the automated prompts (or ask to speak with a representative).

    Have the following ready when you call:

    * Your Capital One credit card number
    * The last four digits of your Social Security Number
    * Your card's CVV (printed on the back)

    Phone activation is available 24/7 through Capital One's automated system.
