Nigeria numbering plan & how to dial
Under country code +234, Nigeria numbers follow an open plan built from a 2-digit area or mobile prefix and a 7-digit subscriber line — 9 digits in all. A domestic "0" typically precedes the prefix, but that digit is dropped when dialing Nigeria internationally.
4 major networks cover Nigeria (MTN Nigeria, Airtel Nigeria, Glo, 9mobile), against 51% internet penetration. VoIP is permitted and regulated by NCC. Because English is the primary language and NGN the local currency, both should inform IVR scripts, SMS content, and support hours.
Across African markets, mobile-first numbering dominates and Tier-1 interconnects are the key to consistent call delivery and CLI presentation.
Skipping the exit code
Reaching Nigeria from the US requires the 011 exit code ahead of +234 — skip it and the call won't connect.
Keeping the national trunk "0"
That leading 0 on a Nigeria number is for domestic calls only; leave it out when dialing in after +234.
Ignoring the time difference
Nigeria runs on UTC+1. Check local hours before dialing so calls don't land outside business time.

FAQ
Calling Nigeria — frequently asked questions
Nigeria uses an open plan: a separate 2-digit area or mobile prefix followed by a 7-digit subscriber number. The prefix is what routes the call to the right region or network once it lands in the country.
The US exit code is 011 for any international call, including to Nigeria. It comes right before the +234 country code, and Twiching adds both automatically when you dial from the app, so you only need to enter the local number.
Calls from Nigeria to the US start at $0.018/min on Twiching, billed per second rather than rounded up to the minute. That rate applies regardless of which of the major local carriers the call originates on.
Calls from the US to Nigeria start at $0.018/min on Twiching, billed per second on Tier-1 routes. That's the same rate whether the call lands on a mobile or fixed-line number in the country.
The major networks in Nigeria are MTN Nigeria, Airtel Nigeria, Glo, 9mobile. Twiching interconnects with Tier-1 carriers for direct delivery to these networks, rather than routing through cheaper wholesale transit that can degrade call quality.
Yes — since Nigeria runs on UTC+1, calls can be routed to the right team based on local business hours there. That's especially useful for support or sales teams covering multiple countries across different time zones from one platform.
