Area code 203 is a telephone area code in the North American Numbering Plan. It serves a specific geographic region, providing a unique identifier for phone numbers within that area. Area codes are essential for routing calls efficiently and are often required when dialing long-distance numbers. They help distinguish between different regions and ensure accurate call connections across the telecommunications network.
