How to Call the USA from Iran?

Before placing an international call from Iran, it’s important to understand the key components of the US phone number format, including the US country code, area code, and subscriber number. It’s also crucial to know about Iran’s exit code, which routes your call internationally from the country.

The exit code signals to the carrier that you’re making an international call. Iran uses ‘00’ as its exit code. You must begin every international call from Iran with this code. However, if you’re calling from a mobile to the US, then you can replace the code with the ‘+’ symbol.

US phone numbers follow a standardized format, including country code, area code, and finally the subscriber number. Each of the codes helps the network route the call accurately to the desired recipient.

• US Country Code: The country code for the United States is 1. This code routes any call from overseas to the US telephone network.
• US Area Code: The area code is a three-digit number that identifies a specific geographic region or state in the US. Every US phone number, mobile or landline, includes an area code.
• Local Subscriber Number: The local subscriber number is the final part of the phone number. It connects the call to the exact person or business you’re trying to reach.

To make calls from Iran to the US, dial the Iranian exit code, the American country code, the area code, and the local number. The dialing process is the same for both landline and mobile numbers.

Here’s how to call the US from Iran:

• Step 1: Dial the Iran international access or exit code, 00 or +.
• Step 2: Enter the US country code, 1.
• Step 3: Enter the 3-digit area code to specify a US city or region.
• Step 4: Enter the 7-digit local subscriber’s number.

To call a US toll-free number from Iran, dial the Iran exit code, the US country code, the toll-free prefix, and the 7-digit subscriber’s number.
 

• Step 1: Dial the Iranian exit code, 00.
• Step 2: Enter the US country code, 1.
• Step 3: Add the toll-free prefix (800, 833, 844, etc.).
• Step 4: Dial the 7-digit subscriber phone number.

Note: Toll-free numbers may not work when calling from outside the United States, or they may incur charges. Always check with your provider first before dialing these special numbers.

The best time to contact the United States from Iran is during US business hours, which correspond to 5:30 PM – 4:30 AM in Iran, as it is about 7.5 to 11.5 hours ahead of the US. For personal calls, it’s best to call in the morning or early afternoon, which aligns with late afternoon to late evening in Iran.

There are notable time differences as both countries follow different time zones. Iran follows Iran Standard Time (UTC+3:30), while the US spans multiple time zones.

The cost of calling the US from Iran depends on the telecom operator you use and your calling plan. On average, prices range from around $0.39 to $0.52 per minute, with most carriers. Rates may vary depending on whether you go for a pay-as-you-go model or a bundle subscription plan.

Here’s the average pricing rate from popular telephone carriers in Iran:
 

You can use virtual phone numbers, calling cards, and social media apps to make calls to someone in the United States from Iran at much lower rates than the traditional carriers.

A virtual phone number lets you make and receive calls over the internet. Though you’ll use the virtual number provider’s Voice over Internet Protocol (VoIP) app for connection, you don’t need the other person to use the same app or another virtual number. You can make and receive calls to regular phone numbers, including landline numbers. VoIP service providers offer these numbers usually with lower international calling rates than traditional carriers.

Prepaid calling cards offer fixed minutes for international calling at lower rates. You’ll pay for the minutes in advance. They are widely available at convenience stores, grocery stores, and online platforms, too. To use a calling card, you’ll simply dial the provided access number, PIN number, followed by the phone number you want to reach.

Many social media platforms are fully or partially restricted in Iran. You can still use local messaging apps such as Soroush Plus to make free calls over the internet. You can also use WhatsApp since its restriction has been lifted as of late 2024/early 2025. However, both parties must be on the same app for the calls, connected via the internet.

Calling the USA from Iran is simple once you know the correct format. Simply dial Iran’s exit code, followed by the US country code and the local number. However, calls through traditional carriers can be costly, and callers may often face networking issues when calling internationally. Calling cards and internet-based options such as virtual phone numbers and messaging apps offer cost-effective alternatives.
