// Calling Etiquette
Nigeria Business Calling Etiquette
Cultural context for calling contacts in Nigeria — know what to expect before you dial.
Network & carriers
Nigeria's telecom market is regulated by the NCC (Nigerian Communications Commission), with MTN, Globacom, Airtel, and 9mobile as the major carriers.
Numbering format
Nigerian mobile numbers are 10 digits after the leading 0, which is dropped when dialing internationally — a domestic 080 number becomes +234 80 abroad.
Calling culture
Nigerian business culture values respectful greetings and a warm opening before getting to the point — jumping straight to business can come across as abrupt.
Good to know
Nigeria's mobile market grew from a small base in the early 2000s to become Africa's largest within roughly two decades, driven almost entirely by mobile rather than landline infrastructure.
