Introduction to Creditcard Regex Go Validator

Validating credit card numbers using regular expressions is crucial in financial applications to ensure data integrity and security. The regex pattern for credit card validation varies depending on the card type but generally follows industry standards. A common pattern might be ^(?:4[0-9]{12}(?:[0-9]{3})?)$ for Visa cards, matching the standard format.

Credit card numbers have specific formats and lengths depending on the card issuer.

The Credit Card Number Regex Pattern

A Visa card number, for example, can be validated with:

import (
    "fmt"
    "regexp"
)

func isValidCreditCard(number string) bool {
    // Define the regex pattern for a Visa card
    var cardRegex = regexp.MustCompile(`^(?:4[0-9]{12}(?:[0-9]{3})?)$`)
    return cardRegex.MatchString(number)
}

func main() {
    testCard := "4111111111111111"
    fmt.Printf("Is '%s' a valid Visa card number? %t\n", testCard, isValidCreditCard(testCard))
}
