In our increasingly interconnected world, where communication is paramount and digital transactions are the norm, the humble phone number has evolved from a simple string of digits into a crucial identifier. Yet, behind the scenes, ensuring the accuracy, validity, and proper formatting of these numbers presents a complex and often overlooked challenge.
