Activate your card by calling the number on the back or using the Chase mobile app

Chase sends new credit cards with a sticker on the front that blocks the card from working until you turn it on. You have two main ways to do this: call the automated phone number printed on the sticker, or open the Chase mobile app and follow the activation prompt. Both take about two minutes. You'll need the card itself and your Social Security number or the last four digits of your Social Security number, depending on which method you choose.

The card won't work at a store, online, or anywhere else until you complete this step. Some people skip this thinking the card activates automatically—it doesn't. If you try to use an unactivated card, the transaction will be declined.

Key Takeaways

  • Call the phone number printed on the sticker attached to your new Chase card, or use the Chase mobile app to activate it within minutes of receiving it.
  • You'll need the physical card and your Social Security number or the last four digits of it to complete activation either way.
  • The card cannot be used for any purchase—in-store, online, or by phone—until activation is finished.
  • Activation is free and does not change your credit limit, interest rate, or any other account terms.

Activating by phone: the fastest route

Look at the front of your new card. There's a white or colored sticker with a phone number printed on it. Call that number from any phone. You don't have to call from your home phone or the phone number on file with Chase—any phone works.

When you call, an automated system will ask you to enter your card number and either your full Social Security number or the last four digits. Follow the prompts. The system will confirm your identity and then ask you to set or confirm a PIN if you haven't already. Once the system tells you the card is activated, you're done. You can use the card immediately.

This method works even if you don't have the Chase app installed or if you prefer not to use your phone for banking. The whole call takes about two minutes.

Activating through the Chase mobile app

If you already use the Chase app, activation is often faster because the app recognizes your new card automatically. Open the app, and you'll usually see a prompt asking if you want to activate your card. Tap yes, and the app will walk you through a few quick steps to confirm your identity.

You may be asked to enter the last four digits of your Social Security number or answer a security question. Once you confirm, the card activates right away. You can start using it within seconds.

If you don't see an activation prompt when you open the app, look for a "Cards" or "Accounts" section and find your new card listed there. Tap on it, and you should see an "Activate" button or link.

What happens if you don't activate right away

There's no deadline to activate your card. Chase will not close your account or charge you a fee if you wait a week, a month, or longer. The card simply won't work until you turn it on.

However, waiting too long can create problems if you forget about the card entirely. If you receive a card and set it aside, you might misplace it or forget you have it. It's easier to activate as soon as it arrives so you know the card is ready if you need it.

Activating a replacement or reissued card

If Chase sent you a replacement card because your old one was lost, stolen, or expired, the activation process is the same. Call the number on the sticker or use the app. The old card will stop working once the new one is activated, so you won't have two active cards at the same time.

If you requested a replacement because your card was compromised, activation also resets any temporary card numbers or digital wallet tokens tied to the old card. You'll need to re-add the new card to Apple Pay, Google Pay, or any other digital wallet you use.

Troubleshooting activation problems

If the automated phone system rejects your Social Security number or the app won't recognize your card, the most common cause is a typo. Hang up or close the app and try again, entering your information slowly and carefully. If you're entering the last four digits of your Social Security number, make sure you're using the right four digits.

If activation still fails after a second attempt, call Chase customer service at the number on the back of your card (or on your statement if you don't have the card yet). A representative can activate the card for you over the phone and can also tell you if there's a problem with your account that's blocking activation. This is rare, but it can happen if Chase needs to verify additional information before the card can be used.

After activation: what to do next

Once your card is activated, you can use it right away. However, before you make your first purchase, take a moment to set up online account access if you haven't already. Go to chase.com, click "Sign In," and then "Enroll" to create your username and password. This lets you check your balance, see transactions, and pay your bill online.

You should also consider setting up automatic payments so your bill is paid on time each month. Late payments hurt your credit score and trigger fees. You can set up autopay through the Chase website or app—choose to pay the full balance, a minimum payment, or a fixed amount each month.

Frequently Asked Questions

Can I use my card before I activate it?

No. Any attempt to use an unactivated card will be declined, whether you're shopping in a store, buying online, or using it over the phone. Activation must happen first.

Do I have to activate my card from home?

No. You can call the activation number from anywhere—work, a friend's house, or while you're out. You don't need to be at home or use a specific phone. The app method also works from anywhere you have internet.

What if I lose my card before I activate it?

Call Chase customer service right away. Tell them the card was lost before activation. They'll cancel that card and send you a replacement. You won't be charged for the replacement, and the lost card can't be used because it was never activated.

Does activation affect my credit score?

No. Activation is just turning on the card so you can use it. It doesn't change your credit limit, trigger a hard inquiry, or affect your credit in any way.

How long does activation take?

Both methods—calling the phone number or using the app—take about two minutes. Your card is ready to use immediately after you finish.
