Understanding Area Codes

What is an Area Code?

An area code (also called STD code or city code) is a numerical prefix used in telephone numbers to identify a specific geographic region. When making calls within the same country, you typically need to dial the area code before the local phone number.

How Area Codes Work

• Domestic Calls: Dial area code + local number (e.g., 010-12345678 in China)
• International Calls: Dial country code + area code + local number
• Local Calls: Within the same area code, you may not need to dial the area code
• Mobile Numbers: Mobile phones typically don't use area codes

Common Use Cases
