Things to Consider When Calling Argentina from the US
Before you dial an Argentine number from the US, it’s important to consider the US exit code and the Argentine phone number format. These key elements play a special role in connecting your call accurately.
The US Exit Code
The US exit code is 011. You must dial this number first when making a call from the United States to another country. It tells your phone carrier that you’re placing an international call and need to connect to a foreign network. However, if you’re calling from a mobile phone, you can simplify things by using the plus sign (+) instead of dialing 011.
The Argentina Phone Number Format
The international phone number format for Argentina includes the exit code, Argentina’s country code (54), an area code (which varies in length by city or region), and the subscriber number (the local number you’re trying to reach). In total, the number you dial can range from 10 to 13 digits. When making international calls, the mobile number includes an additional digit ‘9’ after the country code.

What is the Best Time for Calling Argentina from the US?

For personal calls, consider calling in the early evening, 6:00 PM to 9:00 PM. It's best to call on the weekends for personal calls as people are usually not busy with their day-to-day work on these days.

Affordable Ways to Call from the US to Argentina
Calling cards, virtual phone numbers, and social media apps are cost-effective ways to call Argentina from America. They’re often cheaper compared to traditional calling methods, and even in some cases.
Calling Cards
Calling cards are prepaid cards that let you make international calls at discounted rates. Instead of paying per-minute charges through your mobile plan, you buy credit in advance and use access numbers to place your call.

Social Media Apps
Apps like WhatsApp, Facebook Messenger, Telegram, and Viber allow you to call Argentina for free. But be mindful, both parties must use the same app and have a stable internet connection for calls.
These platforms use VoIP (Voice over Internet Protocol) technology to bypass traditional phone networks and their hefty prices. It’s one of the easiest and most budget-friendly options for international calls.
Virtual Phone Numbers
A virtual phone number allows you to make a call over the internet using a VoIP app or web platform, no SIM card or physical phone line needed. A VoIP service provider often offers these online numbers at a low rate for international calls.
Plus, you can use them on your mobile, laptops, computers, or tablets, whichever one feels handy for you. Just ensure you have a stable internet connection.

Once you get the sequence right, your call should go through without any trouble.
