How to Call Mexico from Abroad: Step-by-Step

To successfully connect a call to a landline or mobile device in Mexico, you must follow the strict international dialing syntax. The format is structured as follows: Exit Code + Mexico Country Code (+52) + Area Code/Network Prefix + Subscriber Number.

• Step 1: The International Exit Code (IDD). Dial your local exit code. For USA, Canada, and Spain, this is typically 00 or 011. On mobile phones, simply hold the '0' key to input a '+' symbol, which acts as a universal exit code.
• Step 2: Input the Mexico Country Code. Once the exit code is entered, dial +52. This instructs the international gateway to route your call towards Mexico.
• Step 3: Drop the Trunk Code (0). Most local numbers within Mexico begin with a 'Trunk Code' (usually a leading '0'). When dialing internationally, you must drop the leading zero.
• Step 4: The Local Number. Finally, enter the unique subscriber number.
