Argentina +54

Argentina, officially the Argentine Republic, is the eighth-largest country in the world and the second-largest in South America. Its telecommunications infrastructure is among the most advanced in Latin America, with a high mobile penetration rate exceeding 90% and a robust fixed-line network that has undergone significant modernization and deregulation since the 1990s. For international callers, understanding Argentina's dialing procedures, numbering plan, and regional nuances is essential for seamless connectivity. This guide provides comprehensive information on how to reach Argentine landlines and mobile numbers, navigate the country's area codes, and manage calls within its borders.

How to Call Argentina from Abroad

Placing an international call to Argentina requires a precise sequence of numbers. The process varies slightly depending on whether you are calling a fixed line or a mobile phone. The general structure is: International Exit Code + 54 (Country Code) + Area Code (without the leading '0') + Subscriber Number. For mobile numbers, the format has evolved to include a '9' after the country code, followed by the mobile area code (without the leading '0') and the subscriber's 8-digit number.

• Calling a Landline: Dial your country's exit code (e.g., 011 from the US, 00 from most European countries), then 54, then the two-, three-, or four-digit area code (dropping the leading zero), followed by the 6- to 8-digit local number. For example, to call a landline in Buenos Aires with the local number 1234-5678, you would dial: Exit Code + 54 + 11 + 1234-5678.
• Calling a Mobile Number: Argentine mobile numbers have 10 digits after the country code: a '9' (mobile discriminator), a three-digit mobile area code (without the leading '0'), and a seven-digit subscriber number. To call a mobile in Buenos Aires, you would dial: Exit Code + 54 + 9 + 11 + 1234-567 (note: the final seven digits). This is a critical distinction from landline dialing.
• Alternative Mobile Dialing: Some operators and older guides may suggest dialing the area code with the leading '0' and then the subscriber number, but the official modern standard for international calls to Argentine mobiles is the '9' prefix after the country code. Always verify with your service provider if you encounter issues.

Understanding Argentine Area Codes

Argentina uses a geographic numbering plan where each city or region has a designated area code. The capital, Buenos Aires, uses the code 11 (which is a two-digit code, but when dialed internationally, it is treated as part of the 11-digit national significant number). Other major cities have three-digit codes (e.g., Córdoba: 351, Rosario: 341, Mendoza: 261). Rural and smaller localities may have four-digit codes. When dialing from within Argentina, you must include the leading '0' before the area code (e.g., 011 for Buenos Aires), but this zero is always omitted when dialing from abroad. The national significant number (NSN) for a fixed line consists of the area code plus the subscriber number, totaling 10 digits (excluding the country code). For mobile numbers, the NSN includes the '9' and totals 11 digits.

Special Rules and Numbering Reforms

Argentina has undergone significant changes to its numbering plan to accommodate the growth of mobile telephony. In 2010, the National Communications Entity (ENACOM) standardized mobile numbers by adding a '9' before the area code for international calls, ensuring that mobile numbers are always recognized as such. Additionally, local calls between fixed lines in the same area code do not require any prefix. However, calls from a fixed line to a mobile within the same city now require the prefix '15' followed by the mobile number (e.g., dial 15-1234-5678 for a mobile in Buenos Aires). This rule often confuses visitors, but it is essential for domestic calling. For international travelers, it is crucial to remember that when roaming, the local '15' prefix is not used; instead, the international format with '9' applies.

Practical Tips for Travelers and Businesses

• Check Your Exit Code: The exit code varies by country. From North America, it is '011'; from the UK, Australia, and many other countries, it is '00'. Japan uses '010', and Brazil uses '00' followed by a carrier code. Always confirm the correct exit code before dialing.
• Mobile-First Strategy: Since over 80% of Argentine adults own a smartphone, calling a mobile is often the most reliable way to reach someone. Use the '9' prefix format for international calls to mobiles.
• VoIP and Apps: For cost-effective communication, consider using VoIP services like WhatsApp, Skype, or Zoom, which are widely used in Argentina. If you need to call a landline, services like Google Voice or Skype Out can offer lower rates than traditional carriers.
• Business Hours: Argentina is in the UTC-3 time zone. When scheduling calls, note that Argentina observes daylight saving time in some provinces, but not the capital. Always confirm the local time to avoid early morning or late-night disruptions.
• Emergency Numbers: For emergencies, dial 101 for police, 107 for medical emergencies, and 100 for fire. These numbers are free from any phone.
