Quick answer: A Nigerian phone number uses country code +234. Inside Nigeria, numbers start with a leading 0 (the trunk prefix); from abroad you drop the 0 and dial +234 instead. Mobile numbers are 11 digits domestically (
0 + 3-digit network code + 7-digit subscriber); the four major carriers are MTN, Airtel, Glo, and 9mobile. Landlines use city codes — many now updated by the NCC with a leading "20" (Lagos01→0201, Abuja09→0209). Nigeria runs on West Africa Time (UTC+1) with no daylight saving.
Nigeria Phone Number Format: A Clear +234 Guide with Examples
You've got a Nigerian contact to call, and the number looks unfamiliar — a leading zero, an extra digit, maybe a plus sign. Dial it wrong and the call dies before it rings.
Nigerian numbers follow a clean logic once you see the parts. This guide from My Country Mobile (MCM) walks through the structure, shows real examples, and clears up the leading-zero confusion that trips up most international callers.
The building blocks of a Nigeria phone number
Every Nigerian number is built from three parts. Knowing each one is the difference between a connected call and a dead line.
- Country code: +234 — always dialed when calling from abroad
- Network or area code: identifies the carrier or city
- Subscriber number: the unique line itself
The country code is +234
When dialing Nigeria from outside the country, the call always starts with +234. That tells your carrier the call is bound for Nigeria.
The leading zero rule
Inside Nigeria, numbers start with a 0 (the trunk prefix). When you call from another country, you drop that 0 and use +234 instead.
So a local number written as 0803 123 4567 becomes +234 803 123 4567 internationally. Never dial both the 0 and the +234 — that's the single most common mistake.
Nigerian mobile number format
Most calls to Nigeria go to mobiles. A Nigerian mobile number is 11 digits long when written nationally, including the leading zero.
The structure is: 0 + 3-digit network code + 7-digit subscriber number. Example: 0803 123 4567.
Dialing a mobile from abroad
Swap the leading 0 for +234. The same 0803 123 4567 becomes +234 803 123 4567 from overseas.
That's 13 digits including the country code. No area code is needed for mobile calls — the network code does that job.

Mobile network prefixes in Nigeria
The three-digit network code originally identified the carrier. Nigeria's four major networks are MTN, Airtel, Glo, and 9mobile.
| Network | Common prefixes |
|---|---|
| MTN | 0803, 0806, 0810, 0813, 0814, 0816, 0703, 0706, 0903, 0906 |
| Airtel | 0802, 0808, 0812, 0708, 0701, 0901, 0902, 0904, 0907 |
| Glo | 0805, 0807, 0811, 0815, 0705, 0905 |
| 9mobile | 0809, 0817, 0818, 0908, 0909 |
Why the prefix no longer proves the carrier
Here's a catch worth knowing. Nigeria launched Mobile Number Portability (MNP) in 2013, so people can keep their number when switching networks.
That means a 0803 number — historically MTN — might now run on Airtel or Glo.
The prefix shows the original carrier, not always the current one. If you need to know the current network (for SMS routing or carrier-specific pricing), a lookup is the only reliable way.
Nigerian landline number format
Landlines work differently. They use geographic area codes tied to a city or region, not a network.
A landline call from abroad follows: +234 + area code (no leading 0) + subscriber number.
The updated NCC landline format
Nigeria's regulator, the NCC, modernized fixed-line numbering. Many landlines now carry a "20" in front of the old city code.
Lagos shifted from 01 to 0201, Abuja from 09 to 0209, and Port Harcourt from 084 to 02084. You may still see older codes in circulation during the transition.
| City | Older code | Updated code |
|---|---|---|
| Lagos | 01 | 0201 |
| Abuja | 09 | 0209 |
| Ibadan | 02 | 0202 |
| Port Harcourt | 084 | 02084 |
| Kano | 064 | 02064 |

Real dialing examples
Examples make the rules stick. Here's how the same numbers look from inside and outside Nigeria.
| Number type | Within Nigeria | From the US / UK |
|---|---|---|
| Mobile (Lagos user) | 0803 123 4567 | +234 803 123 4567 |
| Lagos landline | 0201 234 5678 | +234 201 234 5678 |
| Abuja landline | 0209 876 5432 | +234 209 876 5432 |
Calling Nigeria step by step
From the US, dial 011, then 234, then the number without its leading 0. From the UK, replace 011 with 00.
So a US caller reaching that Lagos mobile dials: 011 234 803 123 4567.
Best time to call Nigeria
Nigeria runs on West Africa Time (WAT), which is UTC+1. The country does not observe daylight saving, so the offset is steady year-round.
Standard business hours are 8 a.m. to 5 p.m., Monday to Friday. For a US caller on Eastern Time, that means dialing in your morning hits the Nigerian afternoon — a comfortable window for both sides.

Frequently asked questions
What is the country code for Nigeria?
Nigeria's country code is +234. You dial it before any Nigerian number when calling from another country, in place of the local leading zero.
How many digits is a Nigerian mobile number?
A Nigerian mobile number is 11 digits when written nationally, including the leading 0. Internationally it's 13 digits, since +234 replaces that zero.
Do I drop the 0 when calling Nigeria from abroad?
Yes. The leading 0 is for domestic dialing only. From overseas, dial +234 and then the number without its 0.
Can I tell the network from a Nigerian number prefix?
Not reliably. Prefixes like 0803 (MTN) or 0805 (Glo) show the original carrier, but Mobile Number Portability since 2013 means the number may now be on a different network.
How do I dial a Nigerian landline from the US?
Dial 011, then 234, then the area code without its leading 0, then the subscriber number. A Lagos landline becomes 011 234 201 234 5678.
What time zone is Nigeria in?
Nigeria uses West Africa Time, UTC+1, with no daylight saving. It's one hour ahead of the UK in winter and the same as the UK in summer.

Yes. A virtual number from a provider like MCM gives you a local +234 line that forwards to your existing phone anywhere in the world.
