Common Patterns

Dates

European date formats typically use the day-month-year format, which differs from the month-day-year format used in the United States.

A regex pattern to match this format can look like this: ^(0?[1-9]|[12][0-9]|3[01])/(0?[1-9]|1[012])/\d{4}$

This pattern checks for a valid day (01 to 31), month (01 to 12), and a 4-digit year. The 0? allows for dates to be written with or without a leading zero (e.g., "1/1/2024" or "01/01/2024").

Currency

To match amounts in euros, which might include commas for thousands separators and a period for the decimal point, you can use the following pattern: ^€\s?\d{1,3}(,\d{3})*(\.\d{2})?$

This pattern supports amounts like "€1,000.00", "€100", and "€ 2,500.50". It ensures there is a euro symbol at the beginning, optional whitespace, followed by a number that may include commas and exactly two decimal places.

Emails

To validate email addresses using a regex pattern that covers most common formats, you can use the following pattern:

  • Pattern: ^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}$
  • Description: This pattern matches standard email addresses that consist of a local part (username) and a domain part. The local part allows letters, digits, dots, underscores, and special characters like %, +, and -. The domain part includes letters, digits, and hyphens, followed by a top-level domain (e.g., .com, .net, .org) with a minimum of two characters.

Examples of valid emails:

This pattern is robust and should work for most email validation scenarios but may need adjustments for edge cases or specific requirements.

Vehicle Registration Codes

Vehicle registration codes in Europe can vary, but a simple pattern to match a generic format might be: ^[A-Z]{1,3}-\d{1,4}-[A-Z]{1,3}$

This pattern allows for 1 to 3 letters, followed by 1 to 4 digits, and then 1 to 3 letters again, all separated by dashes. This format matches some European vehicle registration codes but might need adjustments for specific countries.

Credit and Debit Card Patterns

Below are regex patterns for various types of credit and debit cards. These patterns match the general format of card numbers issued by major card providers.

Keep in mind that these patterns only validate the format, not the actual validity of the card numbers.

Visa

  • Pattern: ^4[0-9]{12}(?:[0-9]{3})?$
  • Description: Visa cards start with a 4 and have either 13 or 16 digits.

Usage

PHP

To use regex patterns in PHP, we can use the preg_match function.

Here's an example of how to validate a German phone number:

$pattern = '/^\+49[1-9][0-9]{1,14}$/';
$phoneNumber = '+491234567890';

if (preg_match($pattern, $phoneNumber)) {
    echo "Valid German phone number.";
} else {
    echo "Invalid German phone number.";
}

Here's an example of how to validate a credit card number:

$patterns = [
    'visa' => '/^4[0-9]{12}(?:[0-9]{3})?$/',
    'mastercard' => '/^5[1-5][0-9]{14}$/',
    'amex' => '/^3[47][0-9]{13}$/',
    'discover' => '/^6(?:011|5[0-9]{2})[0-9]{12}$/',
    'diners' => '/^3(?:0[0-5]|[68][0-9])[0-9]{11}$/',
    'jcb' => '/^(?:2131|1800|35\d{3})\d{11}$/',
    'maestro' => '/^(?:5[0678]\d{2}|6\d{3})\d{8,15}$/',
    'unionpay' => '/^62[0-9]{14,17}$/'
];

$cardNumber = '4111111111111111'; // example Visa card number

foreach ($patterns as $type => $pattern) {
    if (preg_match($pattern, $cardNumber)) {
        echo "Valid $type card number.";
        break;
    }
}

Python

To use regex patterns in Python, we can use the re module, which provides support for regular expressions.

Here's an example of how to validate a German phone number:

import re

# Regex pattern for a German phone number
pattern = r'^\+49[1-9][0-9]{1,14}$'

# Sample German phone number to test
phone_number = '+491234567890'

# Using the re.match function to check if the pattern matches the phone number
if re.match(pattern, phone_number):
    print("Valid German phone number.")
else:
    print("Invalid German phone number.")

Here's an example of how to validate a credit card number:

import re

patterns = {
    'visa': r'^4[0-9]{12}(?:[0-9]{3})?$',
    'mastercard': r'^5[1-5][0-9]{14}$',
    'amex': r'^3[47][0-9]{13}$',
    'discover': r'^6(?:011|5[0-9]{2})[0-9]{12}$',
    'diners': r'^3(?:0[0-5]|[68][0-9])[0-9]{11}$',
    'jcb': r'^(?:2131|1800|35\d{3})\d{11}$',
    'maestro': r'^(?:5[0678]\d{2}|6\d{3})\d{8,15}$',
    'unionpay': r'^62[0-9]{14,17}$'
}

card_number = '4111111111111111'  # example Visa card number

for card_type, pattern in patterns.items():
    if re.match(pattern, card_number):
        print(f"Valid {card_type} card number.")
        break

C#

In C#, we can use the System.Text.RegularExpressions namespace to work with regex.

Here's an example of how to validate a German phone number:

using System;
using System.Text.RegularExpressions;

class Program
{
    static void Main()
    {
        string pattern = @"^\+49[1-9][0-9]{1,14}$";
        string phoneNumber = "+491234567890";

        if (Regex.IsMatch(phoneNumber, pattern))
        {
            Console.WriteLine("Valid German phone number.");
        }
        else
        {
            Console.WriteLine("Invalid German phone number.");
        }
    }
}

Here's an example of how to validate a credit card number:

using System;
using System.Text.RegularExpressions;

class Program
{
    static void Main()
    {
        var patterns = new (string CardType, string Pattern)[]
        {
            ("Visa", @"^4[0-9]{12}(?:[0-9]{3})?$"),
            ("MasterCard", @"^5[1-5][0-9]{14}$"),
            ("Amex", @"^3[47][0-9]{13}$"),
            ("Discover", @"^6(?:011|5[0-9]{2})[0-9]{12}$"),
            ("Diners", @"^3(?:0[0-5]|[68][0-9])[0-9]{11}$"),
            ("JCB", @"^(?:2131|1800|35\d{3})\d{11}$"),
            ("Maestro", @"^(?:5[0678]\d{2}|6\d{3})\d{8,15}$"),
            ("UnionPay", @"^62[0-9]{14,17}$")
        };

        string cardNumber = "4111111111111111";  // example Visa card number

        foreach (var (CardType, Pattern) in patterns)
        {
            if (Regex.IsMatch(cardNumber, Pattern))
            {
                Console.WriteLine($"Valid {CardType} card number.");
                break;
            }
        }
    }
}

Java

In Java, regex functionalities are provided by the java.util.regex package.

Here's an example of how to validate a German phone number:

import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class Main {
    public static void main(String[] args) {
        String pattern = "^\+49[1-9][0-9]{1,14}$";
        String phoneNumber = "+491234567890";

        Pattern r = Pattern.compile(pattern);
        Matcher m = r.matcher(phoneNumber);

        if (m.find()) {
            System.out.println("Valid German phone number.");
        } else {
            System.out.println("Invalid German phone number.");
        }
    }
}

Here's an example of how to validate a credit card number:

import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class Main {
    public static void main(String[] args) {
        String[][] patterns = {
            {"Visa", "^4[0-9]{12}(?:[0-9]{3})?$"},
            {"MasterCard", "^5[1-5][0-9]{14}$"},
            {"Amex", "^3[47][0-9]{13}$"},
            {"Discover", "^6(?:011|5[0-9]{2})[0-9]{12}$"},
            {"Diners", "^3(?:0[0-5]|[68][0-9])[0-9]{11}$"},
            {"JCB", "^(?:2131|1800|35\\d{3})\\d{11}$"},
            {"Maestro", "^(?:5[0678]\\d{2}|6\\d{3})\\d{8,15}$"},
            {"UnionPay", "^62[0-9]{14,17}$"}
        };

        String cardNumber = "4111111111111111";  // example Visa card number

        for (String[] pattern : patterns) {
            Pattern r = Pattern.compile(pattern[1]);
            Matcher m = r.matcher(cardNumber);
            if (m.find()) {
                System.out.println("Valid " + pattern[0] + " card number.");
                break;
            }
        }
    }
}

Ruby

Ruby has built-in support for regular expressions.

Here's an example of how to validate a German phone number:

pattern = /^\+49[1-9][0-9]{1,14}$/
phone_number = "+491234567890"

if phone_number.match(pattern)
  puts "Valid German phone number."
else
  puts "Invalid German phone number."
end

Here's an example of how to validate a credit card number:

patterns = {
  'visa' => /^4[0-9]{12}(?:[0-9]{3})?$/,
  'mastercard' => /^5[1-5][0-9]{14}$/,
  'amex' => /^3[47][0-9]{13}$/,
  'discover' => /^6(?:011|5[0-9]{2})[0-9]{12}$/,
  'diners' => /^3(?:0[0-5]|[68][0-9])[0-9]{11}$/,
  'jcb' => /^(?:2131|1800|35\d{3})\d{11}$/,
  'maestro' => /^(?:5[0678]\d{2}|6\d{3})\d{8,15}$/,
  'unionpay' => /^62[0-9]{14,17}$/
}

card_number = "4111111111111111" # example Visa card number

patterns.each do |type, pattern|
  if card_number.match(pattern)
    puts "Valid #{type} card number."
    break
  end
end

JavaScript

Here's an example of how to validate a German phone number:

const pattern = /^\+49[1-9][0-9]{1,14}$/;
const phoneNumber = '+491234567890';

if (pattern.test(phoneNumber)) {
    console.log("Valid German phone number.");
} else {
    console.log("Invalid German phone number.");
}

Here's an example of how to validate a credit card number:

const patterns = {
    visa: /^4[0-9]{12}(?:[0-9]{3})?$/,
    mastercard: /^5[1-5][0-9]{14}$/,
    amex: /^3[47][0-9]{13}$/,
    discover: /^6(?:011|5[0-9]{2})[0-9]{12}$/,
    diners: /^3(?:0[0-5]|[68][0-9])[0-9]{11}$/,
    jcb: /^(?:2131|1800|35\d{3})\d{11}$/,
    maestro: /^(?:5[0678]\d{2}|6\d{3})\d{8,15}$/,
    unionpay: /^62[0-9]{14,17}$/
};

const cardNumber = '4111111111111111';  // example Visa card number

for (let type in patterns) {
    if (patterns[type].test(cardNumber)) {
        console.log(`Valid ${type} card number.`);
        break;
    }
}

Go

Go has built-in support for regular expressions through the regexp package. Here's an example of how to validate a German phone number:

package main

import (
    "fmt"
    "regexp"
)

func main() {
    // Example: Validate a German phone number
    pattern := `^\+49[1-9][0-9]{1,14}$`
    phoneNumber := "+491234567890"

    re := regexp.MustCompile(pattern)
    match := re.MatchString(phoneNumber)

    if match {
        fmt.Println("Valid German phone number.")
    } else {
        fmt.Println("Invalid German phone number.")
    }
}

Swift

Swift uses the NSRegularExpression class for regex. Here’s an implementation guide:

import Foundation

func validatePhoneNumber(phoneNumber: String) {
    let pattern = "^\\+49[1-9][0-9]{1,14}$"
    
    do {
        let regex = try NSRegularExpression(pattern: pattern, options: [])
        let nsString = phoneNumber as NSString
        let results = regex.matches(in: phoneNumber, options: [], range: NSRange(location: 0, length: nsString.length))
        
        if results.count > 0 {
            print("Valid German phone number.")
        } else {
            print("Invalid German phone number.")
        }
    } catch let error {
        print("Invalid regex: \(error.localizedDescription)")
    }
}

validatePhoneNumber(phoneNumber: "+491234567890")

Perl

Perl is well-known for its native regex capabilities, making it straightforward to implement regex validations:

#!/usr/bin/perl
use strict;
use warnings;

my $pattern = '^\\+49[1-9][0-9]{1,14}$';
my $phone_number = '+491234567890';

if ($phone_number =~ /$pattern/) {
    print "Valid German phone number.\n";
} else {
    print "Invalid German phone number.\n";
}

⚠️ Important ⚠️

The regex patterns provided here are examples and may not cover all cases or nuances of phone number, postal code, VAT number and vehicle registration code formats. You would need to research and verify the patterns for each country.

Also, remember that phone number, postal code, VAT number and vehicle registration code formats can change, so it's good practice to periodically review and update these patterns.

Be sure to test thoroughly and adjust the patterns as necessary to fit your specific requirements.
