You Won’t Believe What Happens When You Dial the Mysterious 403 Area Code Have you ever picked up your phone, dialed a number, and been met with a strange, haunting ring—like something out of a film noir? If you’ve heard whispers about the eerie 403 area code, you’re not alone. This unique 4-digit code, primarily covering portions of southwestern Pennsylvania, has sparked curiosity, urban legends, and even memes—so what’s really behind the mystery of dialing 403? ### What Is the 403 Area Code? The 403 area code was introduced in 1993 as a split from the broader 412 code, which serves Pittsburgh.
