234 Country Code: Nigeria (+234)
Country code 234 (+234) belongs to Nigeria. Nigeria uses the international dialing code +234, assigned by the International Telecommunication Union (ITU) under the E.164 standard. The ISO 3166-1 alpha-2 code is NG.
You will see the same code written several ways depending on origin: +234 (universal + prefix, works from mobile), 00234 (from countries that use 00 as their international exit code — most of Europe, Asia, and Latin America), 011 234 (from the US and Canada), 0011 234 (from Australia), or the bare 234. All refer to the same Nigeria country code. Note: 234 is not a US area code — US area codes are also 3 digits but +234 is the international dialing code for Nigeria, not a domestic US destination.
Nigerian mobile numbers are 10 digits starting with 70, 80, 81, 90, or 91 — dialed as 0XX... domestically and +234 XX... internationally. Landline area codes are 1 digit for Lagos (01), Abuja (09), and Ibadan (02), and 2 digits for most other cities. Mobile dominates in Nigeria; landlines are rare.

Nigeria Telephone System Facts
Calling Nigeria Successfully: Common Mistakes & Best Practices
Most failed calls to Nigeria come from one of four mistakes, not from network problems. The most common is mishandling the leading 0: domestically, Nigeria numbers are written with 0 at the front (e.g. 08021234567), but that 0 is the domestic trunk prefix and must be removed when calling from outside Nigeria. Dial +234 followed directly by the local number without the 0.
The second is misreading the area code on landline numbers — Nigeria area codes are not uniform length (Lagos 1, Abuja 9, Port Harcourt 84), so confirm the city before dialing. The third is dialing during off-hours — Nigeria uses English business hours and consumer phones are usually answered between 8 AM and 9 PM local time. The fourth and most expensive mistake is assuming your US carrier's WiFi calling feature makes the call cheap. It does not — see WiFi calling vs VoIP for international calls for why.
For scam-call awareness: +234 is the legitimate Nigeria country code, and most unsolicited calls from +234 numbers are legitimate calls from Nigeria-based businesses, hospitals, family members, or call centers serving US customers. Caller-ID spoofing exists, so if a call from a +234 number claims to be from a US government agency, your bank, or the IRS, hang up and call the agency back on its published number. Real authorities never demand payment over the phone.
When you are ready to place a call, the cheapest reliable route is to dial +234 from your browser using Kinvo — no app, no carrier add-on, and the per-minute rate is shown before you connect so there are no bill surprises. The browser approach also works from any laptop, tablet, or phone you happen to have access to, which matters when you're traveling, using a work device, or borrowing someone else's computer.
