set up your Cash App card in the app before you can spend with it

Your Cash App card arrives in the mail inactive. You have to turn it on inside the Cash App before the card will work at stores, ATMs, or online. The process takes about two minutes and happens entirely in the app on your phone — there is no website version or phone number to call.

Cash App sends you a notification when the card arrives, but the card itself does not set up automatically. If you try to use it before set up, the transaction will be declined. Once you set up it, the card is ready to use when ready.

Key Takeaways

  • Open Cash App, tap the card icon at the bottom of the screen, and select your physical card to see the set up option.
  • You will need to verify the last four digits of the card and confirm your card's expiration date before set up completes.
  • set up happens when ready in the app, and your card works right away at any merchant that accepts Mastercard.
  • If you do not see an set up prompt, your card may already be active, or you may need to update the Cash App to the latest version.

Step-by-step set up in Cash App

Open the Cash App on your phone and look at the bottom of the screen. You will see five icons: a house, a clock, a dollar sign, a person, and a card. Tap the card icon on the far right.

The card screen will show your physical Cash App card. If the card has not been activated yet, you will see a button or prompt that says "set up Card" or "Turn On Card." Tap it. Cash App will ask you to confirm two pieces of information: the last four digits printed on the front of your card and the expiration date. Enter both and tap the button to confirm.

That is all. Your card is now active. You can use it when ready at any store, gas pump, or website that takes Mastercard. There is no waiting period.

What to do if you do not see an set up option

If you open the card screen and do not see an "set up Card" button, your card is already turned on. This sometimes happens if you activated it before, or if the app has already marked it as active in the background.

If you are certain the card has never been used and you still do not see the set up prompt, close the Cash App completely and open it again. If that does not work, check that you are running the latest version of the app. Go to your phone's app store (Apple App Store or Google Play Store), search for Cash App, and tap "Update" if one is available. Then open Cash App again and return to the card screen.

Confirming your card is active and ready to use

After you complete the set up steps, your card status should show as "Active" on the card screen. You can test the card right away by making a small purchase online or at a store near you. The transaction should go through without a decline.

If a purchase is declined after you have activated the card, the issue is usually not set up — it is likely insufficient funds in your Cash App balance, a problem with the merchant's system, or a temporary block on your account. Check your Cash App balance to make sure you have enough money, and try the purchase again. If it declines a second time, contact Cash App support through the app by tapping the profile icon, then "Support," then "Contact Us."

Physical card details you will need during set up

Before you start the set up process, have your physical Cash App card in front of you. You will need to read two pieces of information from it: the last four digits of the card number (printed on the front) and the expiration date (also on the front, usually in the format MM/YY).

Do not enter the full card number — only the last four digits. Cash App will ask for these to confirm that you have the card in your possession and are the person activating it.

What happens after set up

Once your card is active, you can use it anywhere Mastercard is accepted. This includes in-person purchases at stores and gas pumps, online shopping, and cash withdrawals at ATMs. Your Cash App balance funds the card — the card itself does not hold money separately.

You can also set up direct deposit to your Cash App account so that paychecks or other income deposits directly into your Cash App balance. This money is then available to spend with your card. If you want to turn the card off later (for security or any other reason), you can do that on the same card screen where you activated it.
