PHP Postal Formatter

Labrodev\PostalFormatter is a strict PHP 8.1+ utility library that provides robust formatting for European postal codes, following official formatting standards country-by-country.

Features

• Cleans and standardizes postal codes (removes spaces, symbols, lowercases)
• Supports most of the European countries (45+ ISO 3166-1 alpha-2 codes)
• Automatically formats codes to the standard of each country (e.g. 12345 → 123 45 for CZ, sw1a1aa → SW1A 1AA for GB)
• Ready-to-go static formatter
• Fully typed with strict mode (declare(strict_types=1))
• Includes PHPUnit and PHPStan support for testing and analysis

Installation

composer require labrodev/postal-formatter

Usage

echo PostalFormatter::format('sw1a1aa', 'GB'); // "SW1A 1AA"
