Mobile Number Format and Length

Mobile Number Structure

In Nigeria, mobile phone numbers adhere to a 10-digit format that is consistent across all mobile network operators. This format ensures simplicity in dialing and efficient management of phone numbers. The structure is as follows:

• National Trunk Prefix (0): The first digit is always ‘0’, used when dialing within Nigeria. This prefix is omitted when dialing from outside the country.
• Mobile Network Code (MNC): The next three digits identify the mobile network operator. For instance, ‘080’, ‘070’, ‘081’, ‘090’, etc., represent different operators.
• Subscriber Number: The remaining six digits are unique to each subscriber within the operator’s network.

When dialing from outside Nigeria, the Nigeria country code ‘234’ is used in place of the National Trunk Prefix. This is combined with the exit code and area code for international calls. For example, a typical Nigerian mobile number is written as: 0802 123 4567. Here, ‘0802’ is the MNC, and ‘123 4567’ is the unique subscriber number.

Mobile Number Length

The length of Nigerian mobile phone numbers is fixed at 10 digits. This standard length ensures uniformity and prevents confusion, making it easier for users to remember and dial numbers correctly.

Landline Number Format and Length

Landline Number Structure

Landline numbers in Nigeria differ slightly from mobile numbers and vary depending on the geographic region. The format typically includes:

• National Trunk Prefix (0): As with mobile numbers, the first digit is ‘0’ when dialing within Nigeria.
• Area Code: The next digit(s) represent the geographic area. Area codes can be one or two digits long. For example, Lagos has the area code ’01’, while Abuja uses ’09’.
• Subscriber Number: The remaining digits, which typically range from five to seven digits, make up the unique subscriber number.

To call Nigeria from abroad, you need to use the international dialing format, which includes the country code (+234), followed by the area code without the leading ‘0’, and then the subscriber number. For example, to call a Lagos landline number from abroad, you would dial +234 1 234 5678. For example, a Lagos landline number might be written as: 01 234 5678, where ’01’ is the area code, and ‘234 5678’ is the subscriber number.
