How to Activate Your Credit Card

When you get a new credit card, you often must activate it before you can use it. You’ll typically get your card in the mail along with activation instructions. There may be several ways to activate it, such as by phone, online or via the bank’s mobile app.

Activating a credit card is usually a quick and simple process. Here, we’ll discuss how to activate your credit card, including what happens afterward and how to handle hiccups along the way.

Common ways to activate a credit card

When you receive your credit card, it will typically come with activation instructions. Those are often listed in the letter that comes with your new card. Your new card may also have a sticker with activation instructions. You may have several options to activate your card, including online, by phone or in a mobile app.

The exact steps depend on the lender and the method you choose. You may have to provide personal information (like the last four digits of your Social Security number or date of birth) as well as your card’s information (like the security code).

Online

Typically, you’ll navigate to a specific URL and follow the instructions.

By phone

You may be able to call a phone number to activate your card. You may be prompted to enter certain information.

Through the bank’s mobile app

If your card issuer has a mobile app, you may be able to activate your credit card there by following the prompts.

When can you use your credit card after it’s activated?

In general, you can start using your credit card as soon as you’ve activated it. There typically isn’t a delay between when the card is activated and when you can use it.

Why do you need to activate your credit card?

Credit card activation is a security measure that’s meant to help prevent fraudulent charges. If someone intercepts your credit card in the mail, the activation requirement may help protect you from unauthorized charges.

What if you don’t activate your credit card?

Even if you don’t activate your credit card, the account is still open. However, you generally wouldn’t be able to use your card for purchases. You'd still be responsible for any applicable fees, such as an annual fee.

If you don’t activate your card and use that account for a while, your issuer may close it. The timing depends on the issuer, and they may or may not notify you before this happens.

How do you know your credit card is activated?

If you can’t remember if you’ve activated your credit card, you can call customer service to verify whether the card is active.

Otherwise, attempting to activate the card may provide an answer. If you try to activate the card, you may get a notification that it’s already activated. Otherwise, the activation will be successful.

What to do if you have trouble activating your credit card

Activating a credit card is usually a seamless process, but it’s possible to run into issues along the way. If you’re having trouble activating your credit card, here are some steps you can take:

  • Double-check the information you entered: Make sure this information is correct.
  • Use a different method: If one activation method (like online activation) isn’t working, try an alternative.
  • Contact customer support: When in doubt, calling customer service may help you address your activation issue.

Once you’ve activated your card, you can sign the white or gray box on the back and start using it.
