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.

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.

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.";
}

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.")

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.");
        }
    }
}

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.");
        }
    }
}

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

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.");
}

⚠️ 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.
