## Why You Need to Activate Your Card

Activation is a security measure. When Capital One mails you a new card, it arrives in an inactive state. This protects you in case the card is lost or stolen before it reaches you. Until you activate it, the card cannot be used for any transactions.

Once you activate your card at capitalone.com/activate, you can:

* Make purchases in stores, online, and over the phone
* Withdraw cash from ATMs
* Add your card to Apple Pay, Google Pay, or Samsung Pay
* Earn rewards on eligible purchases immediately

## What You Need to Get Started

Before heading to capitalone.com/activate, make sure you have:

* Your **new Capital One card** (physical card in hand)
* Your **card number** (16 digits on the front)
* Your **date of birth** and **Social Security Number (last 4 digits)** for identity verification
* Access to your **Capital One online account** (or be ready to create one)

<Note>
  If you do not yet have a Capital One online account, you can create one as part of the activation process. Select **Enroll & activate** on the activation page.
</Note>

## What Happens After Activation

Once you complete activation, your card is immediately ready to use. Capital One will confirm activation on-screen and may send a confirmation email or text. You can then:

* Sign in at capitalone.com to manage your card
* Add your card to Apple Pay, Google Pay, or Samsung Pay for contactless payments
* Review your credit limit, due dates, and rewards balance

<Tip>
  Activate your card as soon as it arrives so you can start using it and earning any sign-up bonuses right away.
