Validating credit card numbers with various formats can be achieved using a regular expression. Here's a regex pattern that should work for the formats you've provided: "^(?:\d[ -]*?){13,16}$". This pattern allows for digits, spaces, and dashes between the digits. It requires at least 13 digits and accepts up to 16 digits. You can use this pattern to validate credit card numbers in the formats you've mentioned.
