How to Call the USA from Norway: Dialing Codes, Steps, & Costs

When calling a US number from Norway, consider the exit code for Norway and the key elements of the US phone number format. These include the US country code, the area code, and the local subscriber number.

The exit code is the number you dial first when making an international call. This code routes your call internationally. For Norway, the exit code is 00. When calling abroad from Norway, you must begin the call with this prefix. Or else, your call will not connect to the international telephone network.

A USA phone number format has three key components: country code, area code, and local phone number. The country code for the United States is +1, which routes your call to the US. The area code identifies a specific geographic region within the country. Likewise, the local number identifies the specific phone line of an individual or business.

To call the US from Norway, enter Norway’s exit code (00), the USA country code (1), the area code of the city, and the local phone number.

• Step 2: Dial the United States country code, 1.
• Step 3: Next, enter the area code of the region you’re calling.
• Step 4: Finally, dial the 7-digit local phone number.

For example, if it’s 9:00 AM in New York (Eastern Standard Time), it will be 3:00 PM in Oslo, and if it’s 9:00 AM in Los Angeles (Pacific Standard Time), it will be 6:00 PM in Oslo.

For cost-effective alternatives to calling the US from Norway, use international calling cards, online calling apps, or a virtual phone number.

Calling cards remain a popular method for making international calls at discounted rates. To use them, buy these cards from stores or online, then dial the access number provided. After connecting, enter the card's PIN followed by the receiver’s phone number. While calling cards are cost-effective, be aware that additional fees, such as maintenance fees and activation fees, may apply.

Online calling apps like WhatsApp and Zoom offer a free or low-cost alternative for international calls. These apps use your internet connection (Wi-Fi or data) to place calls. However, both users must be on the same app for calls. And, you won’t be able to make calls to an ordinary landline. To start calling, simply open the app, find the contact, and start a call.

A virtual phone number is a reliable and cost-effective solution for making international calls. It uses VoIP technology to make calls over the internet, bypassing the high rates from the traditional carriers. Unlike the internet calling apps like Skype, Zoom, or WhatsApp, a virtual phone number also allows you to make and receive calls from landlines and regular mobile numbers. You just need to ensure a strong internet connection for your device.

Making calls from Norway to the US is simple once you know the right steps. Always start the call with the Norway exit code 00, followed by 1, the US country code 1, the appropriate area code, and the 7-digit local number.

Besides, you must also consider the time differences between the countries, and the calling cost to ensure your call reaches at the right time at the most affordable price.
