Quick answer: 0812 is MTN.
If someone gives you a number starting with 0812, it’s MTN. Top it up with MTN airtime, buy MTN data for it, and treat it as an MTN line. Done.
But here’s why this matters beyond just knowing the right network to select.
Why This One Detail Saves You Real Money
Last week, Adaeze wanted to send her brother N1,000 in airtime for his birthday. She was almost certain he was on Glo. His number started with 0802, so she grabbed her phone, opened her VTU app, selected Glo, and sent it.
The transaction failed. She tried again. Failed again. After three attempts and twenty minutes of frustration, she finally texted her brother to ask. Turns out he was on Airtel, not Glo. The N1,000 was stuck in limbo.
This happens constantly in Nigeria, and it’s completely preventable.
The wrong network selection wastes your money on failed transactions. Calling someone on a different network costs more on many tariff plans. Trying to top up someone’s account on the wrong network and losing the credit – that’s not just annoying, it’s avoidable.
This guide gives you every Nigerian phone prefix in one place, so you never have to guess again.
Complete List of Nigerian Phone Number Prefixes
MTN Nigeria (0803, 0806, 0703, 0706, 0813, 0816, 0810, 0814, 0903, 0906, 0913, 0916, 0704, 0812)
MTN dominates Nigeria’s telecom market with over 70 million subscribers. That dominance shows in the number of prefixes they control.
If you’re in Nigeria, most of the numbers you interact with are probably MTN. The older prefixes like 0803 and 0806? Early 2000s allocations when MTN was still growing. The newer ones like 0906 and 0913? Added as their subscriber base kept climbing.
Why this matters for you: If you’re managing costs and most of your contacts are MTN, you can use on-net calling rates (cheaper calls within the same network) to lower your bill.
Glo Nigeria (0805, 0807, 0705, 0815, 0811, 0905, 0915)
Glo launched in 2003 and shook up the Nigerian telecom industry immediately. They pioneered per-second billing and undercut everyone on price. It worked. They’re now the second-largest network.
0805 and 0811 are everywhere. You’ll see them constantly across Lagos, Abuja, and most major cities.
Why this matters for you: Glo is known for aggressive data promos. If you know which of your contacts are on Glo, you can take advantage of their frequent data bundle deals.
Airtel Nigeria (0802, 0808, 0708, 0901, 0902, 0904, 0912, 0907)
Airtel’s been around under different names – Econet, Zain, then Airtel. The rebranding happened multiple times, but the network stayed strong.
0802 and 0808 numbers? Those belong to early subscribers who’ve been loyal for years. The 09XX prefixes (0901, 0902, 0904, 0907, 0912) are their newer allocations as they expanded.
Why this matters for you: Airtel’s pricing varies by region. In some areas, they’re competitive on data. In others, MTN and Glo own the market.
9mobile (0809, 0817, 0818, 0908, 0909)
9mobile was Etisalat until the 2017 rebrand. They’re the smallest of the four major networks, which explains fewer prefixes.
They’re concentrated in urban centers but still active, still offering competitive plans, and still in the game.
How to Identify Any Nigerian Number in 10 Seconds
Your Nigerian phone number is 11 digits long, starting with 0. The first four digits are the prefix. That prefix tells you everything you need to know about which network owns it.
The formula is simple:
1. Look at the first four digits
2. Match them to the list above
3. That’s your network
Examples:
– 0803-456-7890 → MTN
– 0805-123-4567 → Glo
– 0802-987-6543 → Airtel
– 0809-111-2222 → 9mobile
Three other ways to confirm (if you’re still unsure):
Call the number: Some networks announce the carrier name when you dial.
Ask them directly: If you’re planning to send airtime or data, this is always the safest move. Takes five seconds. Saves N1,000.
Use the NCC database: The Nigerian Communications Commission maintains the official prefix allocations at ncc.gov.ng. But honestly, the tables everything you need.
Why You Actually Need to Know This
Buying airtime or data for someone else (the most common scenario)
You’re on VTUKing or any VTU platform. You select the network first. If you pick wrong, the transaction fails. Some platforms won’t refund failed transactions immediately. You lose the money until you contact support.
Confirming the prefix takes five seconds. Prevents the entire problem.
On-net calls cost less (if your plan supports it)
MTN on MTN? Cheaper per minute on many plans.
Glo on Glo? Same deal.
Call across networks? Full price.
If you’re on a tight budget and most of your calls go to one network, this adds up. Knowing which of your frequent contacts are on your network means you can route calls strategically.
Data promos are often network-specific
“MTN customers get 10GB for N2,000 this weekend.”
“Glo exclusive: 5GB every Friday for N1,200.”
These deals only work when you buy from the right network. Prefix knowledge means you know exactly which of your contacts can claim which deals.
Gifting data or airtime (happens all the time)
You buy your mom credit. Your sister needs data. Your friend’s balance is low. Every transaction requires the right network selection first.
About Number Portability (The Rare Case)
Nigeria has a national number portability (NNP) system. This means someone can keep their 0812 number even if they switch from MTN to Glo. Technically possible.
Practically? It almost never happens. The vast majority of numbers match their original network assignment. But if someone tells you their 0812 number is now on a different network, it’s possible they ported. When in doubt, ask them directly.
MTN, Glo, Airtel, and 9mobile: The Full Breakdown
Why MTN Has So Many Prefixes
MTN Nigeria started operations in 2001. They’ve been adding prefixes continuously as their subscriber base grew. At 70+ million customers, they need the bandwidth. The 080X, 070X, and 090X prefixes are all MTN allocations spread across their growth timeline.
Newer subscribers? They might get 0906 or 0913. Long-term customers? Probably 0803 or 0806. But the prefix doesn’t tell you anything about their plan, how long they’ve been a customer, or what device they use.
Glo’s Strategy and Prefixes
Glo positioned itself as the disruptor from day one. Cheaper rates. Better bundling. Faster speeds (at the time). Their prefixes reflect steady growth, but not as aggressively as MTN. They still compete hard on price, which is why data-heavy users often have Glo numbers.
Airtel’s Rebrand History and Prefixes
Econet → Zain → Airtel. Two complete rebrandings. Through it all, they maintained their subscriber base and kept adding prefixes. 0802 and 0808 are legacy prefixes from the Econet days. The 09XX block came later as the network expanded under the Airtel brand.
9mobile’s Position
Smaller footprint, fewer prefixes. But still active, still available in most urban areas, and still offering plans. They’re the alternative choice for people who want something different from the big three, or who live in a region where 9mobile coverage works better.
