快速回答： Nigeria's country code is +234. To call a Nigerian number from abroad, dial your exit code (
011from the US,00from Europe, or just+from a mobile), then234, then the number without the leading 0. Within Nigeria, dial all 11 digits including the leading 0. Lagos's area code is 1, Abuja's is 9. Mobile prefixes are 3-digit: 803/806/810/813/814/816/903 = MTN, 802/808/812/901/902/904 = Airtel, 805/807/811/815 = Glo, 809/817/818/908/909 = 9mobile.
What is the +234 country code?
A number that starts with +234 is calling from Nigeria — Africa's most populous country (~220 million people) and biggest economy. The country code was assigned to Nigeria by the ITU under the Africa region's 2-zone (2XX) range.
Nigerian numbers run 10 digits total (after dropping the leading 0 used domestically), in the format +234 X XXX XXXX for landlines or +234 XXX XXX XXXX for mobiles.
This guide comes from My Country Mobile (MCM), a virtual phone provider that issues local numbers across the world.
The anatomy of a Nigerian phone number
A Nigerian phone number has three logical pieces plus the leading 0 trick:
Segment 1: +234 — the country code
Nigeria's ITU country code. Use + from mobiles, 00 from European landlines, 011 from US/Canadian landlines.
Segment 2: The next 1–3 digits
This is where it gets a little different from US numbers:
- For landlines: a single digit area code (
1for Lagos,9for Abuja,2for Ibadan). - For mobiles: a 3-digit prefix that identifies the carrier (
803= MTN,802= Airtel, etc.).
Segment 3: The subscriber number
The remaining 7 digits — the actual unique line.
The leading 0 — the catch
Within Nigeria, every number is written and dialed with a leading 0 (e.g. 0803 123 4567). When you call from abroad, you drop that 0 because +234 already plays the role of the trunk prefix.

| 9mobile | 809, 817, 818, 908, 909 | Formerly Etisalat Nigeria · smaller share |
When a Nigerian gives you a mobile number, the first 3 digits after the 0 tell you immediately which network carries the line.
