How to Call the USA from Iceland? A Step-by-Step Guide

Before you dial a US number from Iceland, it's important to understand the key components of US phone number formats, including the country code, area code, and subscriber number. Together with the Icelandic exit code, these US phone codes ensure your call reaches the intended destination accurately.

An exit code is a part of the international phone number format; you need it to begin every international call. The exit code for Iceland is 00. It informs your telephone network to route your call outside of the country.

US phone numbers have three main parts: the country code, the area code, and the subscriber number.

The country code for the United States is 1. This code directs your call to the US after you’ve dialed the exit code.

The area code comes next. It is a 3-digit number that tells the network which region or city the number belongs to. For example, 212 is the area code for New York City.

The final part is the subscriber number, which is the personal number of the person or business you are calling. The US subscriber number consists of 7 digits.

Calling cards, social media apps like Messenger, Viber, WhatsApp, and virtual phone numbers provide a cost-effective alternative to calling from Iceland to the United States. These services often offer low international calling rates compared to the traditional carriers.

Apps like WhatsApp, Facebook Messenger, and Viber allow you to make voice and video calls over the internet. These apps are free to use as long as both you and the person you’re calling have the app and an internet connection. They’re perfect for personal calls. But it only allows you to make app-to-app calls.

Calling cards are prepaid cards that let you make international calls at lower rates. You simply buy a card, dial a local access number, then enter the PIN and the number you want to call in the US. They are available in many stores and online, and are useful if you don’t have internet access.

A virtual phone number is a cloud-based number that also allows you to make phone calls over the internet. VoIP service providers offer such numbers, often at low cost for international calls. And unlike social media apps, it also allows you to call regular phone numbers. The calls are made through the respective VoIP apps.

The best time to call the US from Iceland is 9 AM to 5 PM local time in the US. These are official hours in the US, making it the best time, especially for business calls. For personal calls, late mornings or early evenings in the US work best.

However, it’s important to consider the time differences between the countries before making a call to ensure your call reaches at a convenient time for your receiver.

Also, Iceland follows a single time zone, Greenwich Mean Time (GMT/UTC+0), all year round, while the United States spans multiple time zones. This makes it even more difficult to identify the best time to call.
