How to Call Nigeria from the US
Calling Nigeria from the United States links a fast-growing Nigerian community across America with family and business contacts in Lagos, Abuja, and every state in between. This guide covers the +234 country code, the leading-zero rule, how Nigerian mobile numbers are built, the time difference, and the cheapest reliable way to call straight from your browser.
Nigeria's country code and the leading-zero rule
Nigeria's country calling code is +234. From a US phone you dial 011 + 234 + the Nigerian number. From a browser-based service like Phonecall you enter + 234 and the number, and the 011 exit code is handled for you, so one saved number works whether you are at home in the US, at work, or travelling.
The catch most callers hit is the leading 0. Nigerian numbers are written nationally with a 0 in front, a Lagos landline appears as 01 XXX XXXX and a mobile as 080X XXX XXXX. That 0 is a domestic trunk prefix and must be dropped when you call from abroad. After +234 you never dial the 0: 01 becomes +234 1, and the mobile 0803 123 4567 becomes +234 803 123 4567.
- Lagos landline: +234 1 XXX XXXX (drop the 0 from 01)
- Abuja landline: +234 9 XXX XXXX (drop the 0 from 09)
- Nigerian mobile: +234 80X XXX XXXX (drop the 0 from 080X)
- Nigerian mobile: +234 70X / 81X / 90X / 91X XXX XXXX
Calling Nigerian mobile numbers
For nearly every US caller, a Nigerian mobile is the destination. Landline use has shrunk so far that the short city codes, 1 for Lagos and 9 for Abuja, now matter mostly for offices and institutions. The vast majority of calls go to a mobile carried by a relative or a business contact.
After you drop the leading 0, a Nigerian mobile is 10 digits. Nationally it is written as 080X, 070X, 081X, 090X, or 091X, so 0803 becomes +234 803, 0706 becomes +234 706, and 0902 becomes +234 902. Those prefixes belong to different carriers, but you do not need to know which, once it is in +234 format, the number connects the same way regardless of network.
Time difference between the US and Nigeria
Nigeria runs on West Africa Time, UTC+1, and the whole country uses a single time zone. Nigeria does not observe daylight saving, so the gap to the US is steady in Nigeria's terms but shifts slightly when US clocks change. In practice Nigeria is about 6 hours ahead of US Eastern in winter and about 5 hours ahead in summer.
That makes scheduling easy. When it is 9 AM on the US East Coast, it is roughly 2 to 3 PM in Nigeria, mid-afternoon, a relaxed time to reach someone. Calling in the early US evening reaches Nigeria late at night, so for unhurried family conversations the US morning and the Nigerian afternoon line up best.
The cheapest way to call Nigeria from the US
US carriers treat Nigeria as an international destination, and without an add-on the per-minute charge to a Nigerian mobile mounts quickly, a long call home or a back-and-forth with a business contact gets expensive. A browser-based VoIP call routes over the internet directly to the Nigerian carrier, so you pay only the destination rate, shown before you dial.
Phonecall is pay-as-you-go: no subscription, no monthly fee, no minimum top-up, and credit that never expires, a natural fit for callers who prefer prepaid calling. Billing is per second rather than rounded up to the next minute, and your first 60-second call is free, so you can confirm a number works before spending anything. App-to-app calls such as WhatsApp are free too, but only reach someone with that app open on a smartphone with data, they cannot ring a Nigerian landline, a bank, or a basic phone.

How to call Nigeria from your browser, step by step
1. Open Phonecall
Go to phonecall.app in Chrome, Safari, Firefox, or Edge on any laptop, desktop, or phone. There is nothing to download and no SIM to swap.
2. Sign in and allow your microphone
Create an account with email or Google, then allow microphone access when the browser asks so the other side can hear you.
3. Enter the number as +234 with the 0 dropped
Type + 234, then the mobile prefix or city code without its leading 0, then the rest of the number. Spaces are fine, they are stripped automatically.
4. Check the rate and press call
The per-minute rate to that Nigerian number appears before the call connects. Press call; your contact answers on their normal phone with no app needed on their end.
Frequently asked questions
What is the country code for Nigeria?
Nigeria's country code is 234. From the US you dial 011 + 234 + the number on a regular phone, or simply + 234 and the number from a browser-based service like Phonecall.
Why do I drop the leading 0 when calling Nigeria?
The 0 at the start of a Nigerian number is a domestic trunk prefix used only for calls placed inside Nigeria. When you call from abroad with +234, you replace that 0, so a mobile 0803 becomes +234 803 and a Lagos landline 01 becomes +234 1. Leaving the 0 in is the most common reason an international call to Nigeria fails to connect.
How do I call a Nigerian mobile number?
Enter + 234, drop the leading 0, and dial the 10-digit mobile number. Nigerian mobiles are written nationally as 080X, 070X, 081X, 090X, or 091X, so 0803 becomes +234 803. The prefix identifies the carrier, but you do not need to know which network, the number connects the same way once it is in +234 format.
What is the time difference between the US and Nigeria?
Nigeria is on West Africa Time, UTC+1, with no daylight saving, roughly 5 to 6 hours ahead of US Eastern. Morning on the US East Coast lands in the Nigerian afternoon, which is usually the easiest window for a relaxed family or business call.
Calling Nigerian mobiles vs landlines
Almost every call from the US goes to a Nigerian mobile, and Phonecall shows the exact per-minute rate for the number you typed before the call connects. Whether you reach a mobile or a Lagos or Abuja landline, the dialing format is the same, +234, no leading 0, and the call runs over carrier-grade HD voice infrastructure for a clear connection.
