You just got your shiny new Capital One credit card in the mail, but before you use it, you need to activate it! Activating it is a pretty simple, straightforward process, but is essential to making the card function as you swipe it across town. In this post, we explain how to activate your new Capital One credit card.

3 Ways To Activate Your Card

Normally, your new Capital One credit card will get shipped to you within 10 business days of being approved, but if you’re lucky enough to be approved for one of Capital One’s premium credit cards, such as the Capital One Venture X Rewards Credit Card, you’re likely to see that card arrive much faster with expedited shipping.

Once your card arrives in the mail, you need to verify that you’ve received it. Up to this point, the card is not usable, even though it looks like it could be. To activate the card, you’ll need to have some essential personal details on hand for Capital One to verify that you’ve received it.

There are 3 ways to activate a Capital One credit card:

The first is using the Capital One website. If you don’t already have an account, you’ll be prompted to create one
If you have the Capital One mobile app installed on your phone, you can use that to activate your card as well
If you’re not able to go to the website or app, you can use the old-school method of calling 800-227-4825

Tips for Activating Your Card

You should activate your card as soon as you receive it. There’s no point in waiting to activate your card. Even though it won’t be usable until you verify you’ve received it, you don’t want to risk losing the card you’ve been sent and having it fall into the wrong hands.
Sometimes, Capital One will ask for personally identifiable information to verify receipt of your card. Generally, if you use the app and log in or use the call-in number using the phone number associated with your account you will not receive this extra scrutiny.
Once you’ve activated your card, be sure to keep it in a safe place as anyone who picks it up can use it. If you lose your card, or it gets stolen, immediately contact Capital One to report the theft and have your card frozen so no additional charges can be made.
If your card has a welcome bonus, be sure you meet all of the requirements so you can earn those bonus points. Often, there is a specific amount of spend you need to put on the card.

Hot Tip: Capital One does not provide access to your credit card number prior to receiving the physical card, so you’ll only be able to activate your card and use it once you receive it. You may have success in adding your card to vendors such as PayPal via the Digital Wallet Manager to use your card before receiving it. Simply navigate to your profile, then Digital Wallet Manager to get started.

Activating your credit card is essential to being able to use it. Capital One makes this process pretty simple, offering a variety of ways to acknowledge that you’ve received the card. Be sure to activate your card as soon as it arrives so you can begin swiping your card at merchants worldwide.
