Introduction

In Java, SSN validation is crucial in applications dealing with personal identification and data processing. Java's java.util.regex package provides the means for regex-based SSN validation.

SSN Regex

Java regex for SSN validation follows the standard 3-2-4 digit format.

The SSN Regex Pattern

  • Pattern: ^\\d{3}-\\d{2}-\\d{4}$

  • This matches SSNs in the "XXX-XX-XXXX" format.

How to Validate SSNs in Java?

To validate SSNs in Java:

import java.util.regex.*;
public class SSNValidator {
    public static boolean isValidSSN(String ssn) {
        String regex = "^\\d{3}-\\d{2}-\\d{4}$";
        Pattern pattern = Pattern.compile(regex);
        Matcher matcher = pattern.matcher(ssn);
        return matcher.matches();
    }
    public static void main(String[] args) {
        String ssn = "123-45-6789";
        System.out.println("Is SSN valid? " + isValidSSN(ssn));
    }
}

Uses of SSN Regex Validation

  1. Personal Data Validation: Ensuring the format of SSNs in user registration, forms, and data entry systems.

  2. Regulatory Compliance: Adhering to legal standards in applications processing sensitive personal data.
