Telephone numbers in Nigeria

Telephone numbers in Nigeria are administered by the Nigerian Communications Commission. Telephone numbers are composed of a combination of an area code and a local line or subscriber telephone number. Area code consist of one digit (Lagos, Ibadan and Abuja) or two digits. Local telephone numbers contain from five to seven digits, and may vary within the area code. Mobile telephone numbers start with 070, 080 or 081, 090 or 091, and are followed by eight digits. They altogether contain eleven digits and vary depending on network.

These examples use calls to Lagos as example:

• xxx xxxx – Calls within the same local area code (Lagos)
• 0201 xxx xxxx – Calls to Lagos from another Nigerian geographic area
• +234 201 xxx xxxx – Calls to Lagos from outside Nigeria
• 0xxx xxx xxxx – Calls to a Nigerian mobile number

The following prefixes are assigned to mobile telephone network operators.^[1] Nigeria implemented mobile number portability in 2013. Therefore, prefixes no longer reliably indicate the parent network of a number.^[2]

Tollfree numbers begin with “0800” (800 without the leading zero), while non-tollfree numbers start with “0700” or 700 without the leading zero. These numbers have 10 digits and are not mobile numbers.

The emergency number is 112.
