The Common Misconception: 011 as an International Dialing Prefix
First things first: In North America (specifically the United States and Canada), 011 is not an area code at all. Instead, it’s the international exit code or prefix used to initiate calls to other countries. When you dial 011 from a U.S. or Canadian phone, you’re signaling to your carrier that the following digits are for an international destination. This is followed by the country code, city or area code, and the local phone number.
For example:
- To call Mexico City from the U.S., you’d dial: 011 + 52 (Mexico’s country code) + 55 (Mexico City’s area code) + local number.
- Calling London, UK: 011 + 44 (UK country code) + 20 (London area code) + local number.
This prefix is part of the North American Numbering Plan (NANP) and has been in use for decades. It’s worth noting that not all countries use 011—many use 00 as their exit code (e.g., in Europe). If you’re receiving calls that appear to start with 011, it could be a spoofed international number or a legitimate call routed through North American systems.
Pro Tip: Always check your phone plan for international calling rates, as dialing 011 can incur extra charges. Apps like WhatsApp or Google Voice can be cost-effective alternatives for international communication.
