A ghost card is a digital or virtual credit card number tied to a business's account, not a physical card. The term “ghost” reflects the card's intangible nature: it exists only electronically, not as plastic.
This can occur for a few different reasons: The 3-digit security code on the back of the Visa, MasterCard or Discover does not match what the card holder's bank has on file. For American Express this is the 4-digit code on the front of the card. The expiration date was entered incorrectly.
No, all Visa cards don't start with the same 4 numbers.

To tell the type of credit card by the number, simply look at the first digit of the credit card number, either on the front or back of your card. The first digit of an American Express card is 3, while it's 4 for Visa cards, 5 for Mastercards, and 6 for Discover cards.
A $4,000 credit limit is good if you have fair to good credit, as it is well above the lowest limits on the market but still far below the highest. The average credit card limit overall is around $13,000. You typically need good or excellent credit, a high income and little to no existing debt to get a limit that high.
An invalid card number means that the card is likely closed at the card issuing bank and is effectively an invalid card. If the cardholder says that the card is not closed, then the cardholder should contact the card issuing bank to resolve the issue.
A common reason why your card hasn't worked for an online purchase is you've accidentally entered in the wrong card number, expiry date or CVV number. All it takes is one number to be wrong, which is an easy error to make.
