Why Cash App Keeps Saying Invalid Card Number
Short Answer: There can be multiple reasons why Cash App keeps saying Invalid Card Number, such as you are entering wrong credentials like wrong CVV, Expiry Date, or card number, you are using an expired card, your card is not supported on Cash App, and more.
Let’s have a look at all the possible reasons why Cash App keeps declining your card or keeps saying your card number is invalid.
1. You are entering wrong Card details
To begin with, make sure that you are entering the correct card details. Most people get the invalid card number error because they enter the wrong details of their card.
So, before doing anything else, make sure you are entering all the card details correctly. There are many details on the card which you could be entering wrong, such as card number, CVV number, Expiry date, Card holder name, etc.
- Card Number
Most people enter the wrong card number while registering or adding it. As the card number consists of 16 digits. There is high chance that you might misplace a digit while entering.
So, get your card with you and enter every digit carefully.
- CVV Number
Another card detail, which can be entered incorrectly is the CVV number or the card verification value.
It is a 3 or 4-digit number, usually printed on the backside of your debit or credit card. It is also called card security code or card verification code and acts as an additional security layer protecting your data for online transactions or card swipes at POS machines.
- Expiry Date
The expiry date is another card detail you might be entering wrong while registering your card in Cash App.
The expiration date can be found on the front of the card, written in XX/XX (month/year) format. Generally, a card can be used through the last day of the month in which it expires.
For example, a card with an expiration date of 12/22 is valid until December 31, 2022
So, make sure to enter your card’s expiry date in the cash app in the correct format.
- Card Holder Name
The next card detail is the Card holder’s name. It refers to the person who owns the debit or credit card. The cardholder’s name is generally printed on the card.
In case you are entering your nickname or something else in the name section while linking your card in Cash App, you will get the invalid card error.
Make sure you are entering the exact name printed on your card.
2. Your Card has Expired
If you have entered all your details correctly and still Cash App is not accepting your Card or saying your Card is invalid, then it’s possible that your debit card has expired.
So, make sure you are not using an expired card.
As stated above, the expiry date can be found on the back front of the Card.
3. Card is not authorized for Internet transactions
Another possible reason why Cash App is not accepting your Card or showing your Card as invalid is that your Card does not support a certain type of online transaction. For example, some cards can only be used for specific business categories, like travel or healthcare.
In this case, you will need to contact your Bank support and ask them about it.
4. Your Card is not activated
If have recently ordered a brand new card and are trying to add it to the Cash App, make sure you have activated it.
