What Does “Invalid Card Number” Mean?

An “invalid card number” pop-up is essentially trying to tell you that your card is probably closed by the issuer.

But if the card isn’t closed, then why is Cash App saying your card number is invalid?

Why Is Cash App Saying “Invalid Card Number”?

There may be various reasons you’re unable to link your debit card to your Cash App and hence receive “invalid card number” messages. Let’s have a look at some of them.

1. The Card Is Expired

If you’re having trouble linking your debit card to Cash App, then you should check if your card has expired or not.

You may have noticed a date on the front of your debit card. That date is the expiration date of your card.

Usually, cards are valid for three to four years after the date of issue.

2. You May Be Entering the Wrong Card Details

This is a common cause of most Cash App debit card declines.

You need to enter the card details more carefully and make sure that you don’t make any errors.

Here are a few details on your card that you could be entering wrong into Cash App.

The Card Number

The card number is made up of 16 digits. Considering the number of characters, it can be very easy to swap digits while entering them.

After entering the numbers, go over them before hitting the submit button.

CVV Number

Aside from the card number, you can also enter the wrong CVV number. CVV (Credit Verification Value) is a security feature common with banking transactions.

The CVV number is a set of 3 to 4 digits normally found on the back of your card. It’s sometimes called the card verification code or a security code.

Expiry Date

Your card’s expiration date is imprinted on the front of it, written in the month/year format. 

Entering the date in the right format is as important as entering the right digits.

Card Holder Name

The last detail is the card holder’s name which is boldly imprinted on the front of the card. 

You shouldn’t include names that aren’t on the card, and the names must be entered in the right order, as well.

3. Your Card Isn’t Activated

If you order a new card and attempt to add the non-activated card to Cash App, the app can decline your card.

You can contact your bank to guide you through the activation process or when you run into any glitches while doing so.

4. Cash App Doesn’t Support Your Card

Cash App doesn’t support every debit and credit card type. The only cards it works with are:

  • Mastercard
  • American Express
  • Visa 
  • Discover

Cash App doesn’t accept PayPal, business debit, or ATM cards. Therefore, you’ll be sent an “invalid card number” notification if you try to link cards from these providers.

5. You Have Linked the Wrong Bank Account

Linking the wrong bank account may be another reason Cash App is stopping you from going through with your card linking process. 

Make sure you have linked the bank account connected to your debit card before you attempt to register the card in the app.

6. Your Card Isn’t Authorized for Internet Transactions 

Cash App can also decline your card if it hasn’t been authorized for a particular type of internet transaction.

For example, some cards are only allowed to be used for specific transactions like healthcare. If that may be the problem, then contacting your bank about it is the best option.

7. Your Application Is Outdated

Cash App might give you the “invalid card number” message if the app’s version is outdated. So make sure to update Cash App on your device. 

After you update your Cash App version, clear the app’s cache and data using the following steps:

  • Go to “Setting”s on your device
  • Find the “Applications” option
  • Select “Cash App”
  • Tap on the “Clear Cache” button

If you’ve tried everything and the issue persists, the next thing to do is to contact your bank. It might have a solution to your problem.

However, if the bank tells you that everything is clear from its side, then your only option is to contact Cash App Support.
