Some numerical combinations in the above pattern are not valid credit card numbers. For more information, see Data Type Validation Patterns.
When values are validated against the Credit Card data type, the Designer Cloud® application validates the values using regular expressions. This regular expression method checks for general Credit Card patterns and is fast to evaluate.
However, some values may follow the regular expression validation pattern but are not accurate credit card numbers. These values may be detected as valid values.
