Your fancy new card just arrived in the mail, and you’re itching to break it in. But wait, there’s one last step to take: activating.

Most major credit card issuers make it pretty easy for you to activate a credit card online or by phone. Here’s an issuer-by-issuer breakdown on how to activate and use your new card.

Jump to issuer-specific instructions with the table below, or read on for a bit of background information on credit card activation.

Activating a New Credit Card

When you apply for a new card and are accepted, you’ll usually receive the physical card via standard mail within 7–10 days.

It can sometimes arrive sooner, and you may be able to request expedited shipping from the card issuer. If one of your credit cards is lost or stolen and you request a new one, you’ll need to activate that card once you receive it.

Most of the time, your credit card will arrive in a nondescript white envelope (standard or large), with a sticker on the front of the card showing you a phone number and potentially a website for activating.

After activating online or by phone, your new card will usually be ready for use immediately.

Insider tip

Take note that your account is probably open even if you don’t activate your card, because when applying you usually agree that you want the account if approved.

Information to Have When Activating a Credit Card

You may need to have the following pieces of information handy when you call or go online to activate a credit card:

  • Your credit card number
  • The security code on the front or back of your card (often called the card identification number (CID) or card verification value (CVV))
  • Full name, Social Security number, zip code, and/or date of birth
  • Your account number with the issuer (if different than the card number; not usually necessary)

The information you’ll need varies by issuer, and can depend on whether you already have another account with the company as well (you may need to confirm less information if you’re logged in to your account).

Insider tip

If you’re calling to activate a new card, call from the phone number associated with your credit card account to avoid having to provide additional information.

Insider tip

We don’t usually recommend using Credit One credit cards, as they tend to have high fees and we’ve received many complaints about poor customer support. Don’t get Credit One confused with Capital One!

If you use a mobile wallet, like Apple Pay or Google Pay, you can add a new card there once it’s been activated. Replacement cards will usually update automatically in the app.

Sometimes if you’re replacing a credit card that is already in your mobile wallet, the new card may automatically appear there (where it can be used for purchases) even before you receive your new physical card.

Apple Pay and Google Pay.

What If I Don’t Receive My New Credit Card?

If you’ve been approved for a new credit card and haven’t received it after about 21 days, you should contact your credit card issuer to ensure it hasn’t been activated by someone else who is using your card to commit fraud.

It may have also been lost in the mail, so the company might need to issue you another card.
