How to Call the US from Argentina? 4 Simple Steps

First, you must know the calling code from Argentina to the US​ and the latter’s phone number format before initiating a call.

The exit code of Argentina, like most of the other South American countries, is 00. This code notifies your network operator that you are making an international call. Moreover, if you’re calling using a cell phone, you can replace the exit code with the “+” symbol.

The US phone number format is the same for both its landline and mobile numbers, and they are 10 digits long. The first three digits are area codes, followed by a three-digit central office/exchange code, and the last remaining four digits are the subscriber’s number.

Additionally, since you are making an international call, do not forget to include the US country code, i.e., 1, before the 10-digit phone number.

To call the US from Argentina, first dial Argentina’s exit code, followed by the US country code and your intended recipient’s phone number.

• Step 1: Enter Argentina’s exit code 00 or the “+” symbol.
• Step 2: Dial the US country code 1.
• Step 3: Enter the 3-digit area code.
• Step 4: Dial the remaining phone number.

To call a toll-free number in the USA from Argentina, enter Argentina's exit code, the US country code, and the toll-free number.

The best time to call the US from Argentina is during standard US business hours, typically between 9:00 AM and 5:00 PM. However, since the US spans multiple time zones and there’s a noticeable time difference between the two countries, finding the right time can be tricky.

So, here’s a table showing the appropriate hours to contact the US based on its business hours:

Note: The actual time difference may vary by 1 to 2 hours due to Daylight Saving Time (DST) observed in most parts of the US. Always double-check with a world clock or online converter before calling.

Calling the US from Argentina using traditional mobile or landline networks can often lead to high charges, especially for frequent or long conversations. Luckily, there are several cheaper alternatives that help you stay connected without stretching your budget.

Calling cards are prepaid services that allow you to make international calls at lower rates. You simply dial a local access number, enter your PIN, and then dial the US number. They’re a good choice if you’re calling from a landline or don’t have access to mobile data. For international calls from Argentina to the US, some cards offer special discounted rates, making them more cost-effective than direct dialing through your network provider.

Apps like WhatsApp, Viber, and Facebook Messenger let you make voice or video calls using the internet. You just need a stable Wi-Fi or mobile data connection. However, both you and the person in the US must be registered users of the same app. While not ideal for contacting official phone numbers, these platforms are great for casual calls with friends or family.

VoIP (Voice over Internet Protocol) services use the internet to place calls, often at significantly reduced prices. These include virtual network operators that offer international calling services with extra features. Providers, such as Calilio, offer virtual phone numbers, low-cost international calling, and tools like call recording and call forwarding, making it suitable for both personal and business communication with the US.

Calling the United States from Argentina doesn’t have to be difficult or expensive. Whether you’re trying to reach friends, family, or business contacts, you have multiple options to stay connected. While traditional calling methods work, they cost more, especially for regular or long-distance conversations. That’s why many people are turning to alternative methods like calling cards, messaging apps, and especially VoIP services.

Among all the options, VoIP platforms like Calilio stand out for their affordability and convenience. After subscribing to any Calilio package, you even get a free US virtual phone number. This allows you to make calls to the United States from Argentina at cheaper rates. It’s suitable for anyone looking to maintain consistent communication across borders without worrying about high international fees.
