Introduction to Phone Number Regex

Validating phone numbers in Java is essential in applications that require user communication or data integrity. Java's java.util.regex package provides the necessary tools to implement regex for effective phone number validation. A common regex pattern for phone numbers might be ^\\+[1-9]\\\\d{1,14}$, which aligns with the E.164 international phone number formatting.

What is Phone Number Regex?

The international phone number format typically includes a country code, followed by the local number.

The Phone Number Regex Pattern

  • The regex pattern: ^\\+[1-9]\\\\d{1,14}$

  • This pattern ensures the phone number starts with a +, followed by a country code and the local number.

How to Validate Phone Numbers in Java?

In Java, phone number validation can be achieved using the Pattern and Matcher classes:


import java.util.regex.*;

public class PhoneNumberValidator {
    public static boolean isValidPhoneNumber(String phoneNumber) {
        String regex = "^\\+[1-9]\\d{1,14}$";
        Pattern pattern = Pattern.compile(regex);
        Matcher matcher = pattern.matcher(phoneNumber);
        return matcher.matches();
    }

    public static void main(String[] args) {
        String phoneNumber = "+12345678901";
        System.out.println("Is the phone number valid? " + isValidPhoneNumber(phoneNumber));
    }
}

Uses of Phone Number Regex Validation

  1. User Input Verification: Ensuring that phone numbers entered in web forms, registration pages, or databases are in the correct format.

  2. Data Standardization: Maintaining consistency in phone number formats within data sets, crucial for database management and data analysis.
