Nigerian phone numbers: networks and their number codes

Nigeria remains Africa's largest mobile market, with well over 160 million active connections across its network operators. Every Nigerian phone number carries a prefix that once pointed to a single network. With mobile number portability now over a decade old, identifying a number correctly takes a bit more than memorising a prefix list. Here is an up-to-date guide to Nigerian phone numbers, their network codes, and how the numbering system works.

Key takeaways

• Nigerian phone numbers use the country code +234, followed by a 10-digit national number (excluding 234), commonly written locally with a leading 0 for 11 digits in total.
• Prefix codes originally identified a number's network. For example, 0803 and 0906 for MTN, 0805 and 0905 for Glo, 0802 and 0902 for Airtel, and 0809 and 0909 for 9mobile (now rebranded T2).
• Older CDMA-era operators such as Starcomms, Multi-Links, Smile, and ZoomMobile are now defunct or inactive, though their old prefixes still appear on legacy numbers.
• Mobile Number Portability (MNP), active since 2013, means a number's original prefix no longer guarantees its current network, since subscribers can switch operators and keep their number.
• Virtual or free Nigerian phone numbers exist mainly for temporary SMS verification (including WhatsApp sign-up) rather than as a permanent phone line.

Nigerian phone numbers: all you should know

Every Nigerian phone number starts with the country code +234. Below is a look at all critical information you should know about your phone number.

Nigerian phone numbers and prefix codes

Below is an updated table of Nigeria's mobile network operators and the prefix codes originally assigned to each. Due to mobile number portability, a prefix shows a number's original network, not necessarily its current one.

List of MTN numbers in Nigeria

MTN Nigeria, launched in 2001, remains the country's largest network by subscriber count. Its original prefix, 0803, was later joined by 0703, 0706, 0806, 0810, 0813, 0814, 0816, 0903, 0906, 0913, and 0916 as demand for new lines grew.

MTN also absorbed the former Visafone network, which brings the prefixes 0704, 07025, and 07026 under the MTN umbrella.

Glo, Airtel, and T2 (formerly 9mobile) numbers

Glo (Globacom), founded in 2003, is known for its data plans and fibre network, and its numbers span the 0705, 0705, 0807, 0811, 0815, 0905, and 0915 prefixes.

Airtel Nigeria, part of Airtel Africa, launched the same year as MTN and covers the 0701, 0708, 0802, 0808, 0812, 0901, 0902, 0904, 0907, 0911, and 0912 prefixes.

9mobile, previously known as Etisalat Nigeria, rebranded again in August 2025 under the name T2. The rebrand changed the network's name and branding, not its number ranges. T2 still owns the 0809, 0817, 0818, 0908, and 0909 blocks.

Nigerian phone numbers for WhatsApp and free/virtual numbers

Nigerian phone numbers for WhatsApp generally fall into two categories:

• A regular MTN, Glo, Airtel Nigeria, or T2 SIM registered in your own name
• A temporary virtual number used purely to receive a one-time verification code

Free Nigerian phone numbers, sometimes advertised as a '100 Nigeria phone numbers', are typically virtual numbers offered by third-party SMS-receiving services for short-term verification use rather than an actual, dedicated phone line.

These numbers are usually shared publicly, expire quickly, and are not suitable for an account you intend to keep. A real, NIN-linked SIM is the more reliable option for anything long-term, including WhatsApp Business accounts.

How to check a phone number owner's name in Nigeria

Since 2020, the Nigerian Communications Commission (NCC) has required SIM cards to be linked to a National Identification Number (NIN), which ties every registered number to an identity on record with the network operator.

That said, telecom operators do not disclose a subscriber's personal details to the public as doing so would breach Nigeria's data protection rules. Therefore, there is no official public database where you can look up a name and phone number list by searching a number.

In practice, people trying to identify an unknown caller rely on caller-ID apps such as Truecaller, which cross-reference numbers saved in other users' contacts, or they report suspicious numbers directly to their network's customer care or the NCC.

Neither method guarantees a verified legal name, so they are best treated as a rough guide rather than a formal ownership check.

In Nigeria, the NCC continues to manage the National Numbering Plan and periodically issues new prefix blocks as operators need them, so this list may expand further later in 2026.

You can check the prefix. MTN numbers commonly start with 0703, 0706, 0803, 0806, 0810, 0813, 0814, 0816, 0903, 0906, 0913, or 0916, while Airtel numbers start with 0701, 0708, 0802, 0808, 0812, 0901, 0902, 0904, 0907, 0911, or 0912. It is necessary to keep in mind that a ported number may no longer be associated with its original network.

How do you identify a Nigerian network number?

All Nigerian phone numbers start with the prefix code +234. Conversely, each mobile network operator has specific prefixes assigned to them. By familiarising yourself with the prefixes discussed above, such as 0803, 0805, or 0901, you can determine which network a phone number belongs to.

Nigerian phone numbers follow a consistent structure. The country code is +234, followed by a network prefix, and a subscriber number. Today, mobile number portability means that the structure tells you a number's origin more reliably than its current network. Whether you're trying to identify an MTN, Glo, Airtel, or T2 number or to save a contact correctly, the prefixes and format covered here remain the fastest way to make sense of any Nigerian phone number in 2026.
