Dialing Codes Involved While Calling USA From Nigeria
Calling the United States from Nigeria requires using the correct dialing sequence, including the Nigerian exit code, the U.S. country code, area code and the subscriber number. It ensures your call connects accurately to the intended person or business.
1. Nigerian Exit Code
Any international calls from Nigeria begin with the 009. Without dialing this code, the network would treat your call as local, and it would not be routed internationally.
2. Country Code
The United States country code is 1, which identifies the call as being directed to the U.S. and ensures it enters the American telephone system. This code allows the network to recognize the US as the destination country before routing the call to the specific city or region.
3. Area Codes in the USA
After the country code, the 3-digit US area code is required to identify the specific city or region you are calling. For example, you’d dial 212 for New York or 310 for Los Angeles.
Here are some of the popular area codes of the United States:
City/Region | Area Codes |
| Los Angeles, California | 213, 323, 310, 818, 424 |

Alternative Methods to Call the US from Nigeria
Calling Cards
A calling card is a prepaid option to make international calls by purchasing minutes in advance. They are a good alternative when you do not have internet access. However, many cards come with expiry dates, connection fees, or hidden rate changes, so it’s important to check the terms before buying and using them.
Wi-Fi Calling
Wi-Fi calling is a built-in phone feature that lets your calls go through a Wi-Fi network instead of a mobile signal, with no extra app needed. However, availability depends on the device model and your carrier. Once enabled in phone settings, calls are placed from the regular dialer, using the same phone number.
Social Media Apps
Social media apps like WhatsApp, Messenger, and Signal let you make calls using Wi-Fi or mobile data instead of regular mobile networks. The call is made between the apps, meaning both parties must use the same app during the call. The call quality also depends on how stable and strong your internet connection is.
VoIP Services
Voice over Internet Protocol (VoIP) phone services also allow you to make calls over the internet using virtual phone numbers. But unlike social media apps, you can call regular landlines and mobile numbers. The calls are made through VoIP apps, available on smartphones, laptops, desktops, and tablets.
What’s the Best Time to Contact the US from Nigeria?
