Buying a used or fairly expensive phone in Nigeria can be a great way to save money, but it can also come with risks. A phone may look perfect on the outside and still have problems that are difficult to notice during a quick inspection.
One of the simplest checks you can make before paying for a phone is to find and verify its IMEI number.
IMEI stands for International Mobile Equipment Identity. It is a unique number used to identify a mobile device on cellular networks. Checking the IMEI can help you compare the phone with its packaging and other records, identify possible warning signs, and make a more informed buying decision.
This guide explains how to check a phone’s IMEI before buying in Nigeria, where to find the number, what to look for, and what other checks you should perform before handing over your money.
What Is an IMEI Number?
An IMEI is normally a 15-digit number associated with a mobile device. Think of it as an identification number for the phone itself.
The IMEI is different from your phone number. Your phone number identifies your mobile line, while the IMEI identifies the device.
A phone with two SIM slots may have two IMEI numbers, because each cellular connection can have its own device identifier. Therefore, when checking a dual-SIM phone, it is important to check all the IMEI numbers displayed by the device.
IMEI information is important because mobile network operators and regulators can use device identifiers when managing devices on telecommunications networks. The Nigerian Communications Commission (NCC) has explained that an IMEI-based Device Management System can help address illegal devices, duplicated or cloned IMEIs, stolen devices and consumer protection concerns.
However, an IMEI check should not be treated as a complete guarantee that a phone is safe to buy. It is one part of a wider inspection.
How to Check a Phone’s IMEI Number
There are several easy ways to find a phone’s IMEI.
1. Dial *#06#
One of the quickest methods is to open the phone application and dial:
*#06#
On many phones, the IMEI number will appear immediately on the screen.
Write down the number or compare it directly with the information shown elsewhere on the device.
If the phone displays more than one IMEI, record each number.
2. Check the Phone Settings
You can also find the IMEI through the phone’s settings.
On many Android phones, the option is located under something similar to:
Settings → About Phone → Status → IMEI Information
The exact menu can vary depending on the manufacturer and Android version.
On an iPhone, you can generally find it under:
Settings → General → About
Look for the IMEI field.
The important thing is not the exact menu name but whether the IMEI shown in the settings matches the number displayed using *#06# and the information supplied with the phone.
3. Check the Original Box
If the seller has the original phone box, look for the IMEI label.
The IMEI printed on the box should correspond with the device you are inspecting.
A mismatch does not automatically prove that the phone is stolen or fake. For example, the box may have been replaced, or a seller may have accidentally mixed up boxes. However, a mismatch is a reason to stop and investigate before making payment.
Do not allow a seller to pressure you into ignoring an unexplained difference.
Why Should You Check IMEI Before Buying a Phone in Nigeria?
Checking the IMEI can help you identify potential problems before you spend your money.
Here are some of the main reasons to perform an IMEI check.
To Identify Possible Stolen Devices
A phone may be offered at a price that appears too good to be true because there is a problem with its ownership history.
An IMEI can be useful when investigating whether a device has been reported or flagged. Nigeria’s telecommunications regulator has identified stolen phones and flagged IMEIs as an area where device-management systems can help protect consumers and discourage the use of stolen devices.
However, do not assume that every online IMEI checker has access to Nigerian carrier or law-enforcement databases.
To Detect Suspicious IMEI Information
Another warning sign is an IMEI that does not match across different parts of the phone.
For example, you may find:
- One IMEI in the phone settings
- A different IMEI when using *#06#
- Another number printed on the box
These inconsistencies deserve further investigation.
Duplicated or cloned IMEIs are also a recognised concern in mobile-device management. The NCC has specifically identified cloned or duplicated IMEI numbers as a problem associated with illegal devices.
To Confirm the Device You Are Actually Buying
An IMEI check should form part of your basic pre-purchase inspection.
If the seller gives you a particular phone but the packaging belongs to another device, you need to know why.
The goal is simple: make sure the physical phone, its software information and its documentation tell a consistent story.
Is There an Official IMEI Checker in Nigeria?
This is an important question because many websites claim to offer IMEI checks.
The NCC regulates telecommunications equipment and publishes type-approval regulations for communications equipment in Nigeria. Its regulatory framework includes Type Approval Regulations 2024 and related business rules.
However, consumers should be careful about assuming that any website advertising an “NCC IMEI checker” is an official Nigerian government service.
Before entering an IMEI number into a website, check who operates the service, what information it provides, and whether it clearly identifies its source of data.
A website that simply tells you a phone’s model based on an IMEI is not necessarily confirming that the phone is legally owned, has never been stolen, or will work on every Nigerian network.
For official regulatory information, use the NCC’s own website and consumer channels rather than relying solely on an unknown third-party IMEI website.
How to Check if an IMEI Matches the Phone
When buying a used phone, perform this simple comparison:
Step 1: Dial *#06# on the phone.
Step 2: Write down the IMEI number or numbers.
Step 3: Open the phone’s settings and locate the IMEI information.
Step 4: Compare the IMEI in the settings with the result from *#06#.
Step 5: If the original box is available, compare the IMEI printed on the box.
Step 6: If there are inconsistencies, ask the seller for an explanation before paying.
For dual-SIM devices, make sure you check all displayed IMEI numbers rather than checking only the first one.
What Does a Clean IMEI Mean?
People often use the phrase “clean IMEI” to describe an IMEI that does not appear on a particular blacklist or flagged-device database.
But the meaning of “clean” depends on the database being checked.
This is why you should be cautious when a seller says, “The IMEI is clean,” without showing you what was actually checked.
A clean result from one service does not necessarily prove everything about a phone’s history.
For example, an IMEI check may not tell you:
- Whether the seller legally owns the phone
- Whether the phone has been repaired
- Whether replacement parts are genuine
- Whether the phone has water damage
- Whether the battery has deteriorated
- Whether the phone is locked to another service
- Whether it has an outstanding financial obligation
- Whether all of its features work correctly
An IMEI check is useful, but it should never replace a complete physical and software inspection.
How to Check a Used iPhone Before Buying in Nigeria
If you are buying a used iPhone, start with the IMEI, but do not stop there.
Check the IMEI in the phone and compare it with the box where available.
Then inspect the device for signs of damage.
Check:
- Face ID or Touch ID
- Cameras
- Speakers
- Microphone
- Charging port
- Wi-Fi
- Bluetooth
- Mobile network connection
- Screen and touch response
- Battery health
- Buttons
- Flash
- SIM functionality
Most importantly, make sure the previous owner has properly removed their Apple account from the device.
A phone that is still protected by another person’s account can create serious problems for the next buyer.
Never assume that because the phone looks new, everything is fine.
How to Check a Used Android Phone Before Buying
The same principle applies to Samsung, Google Pixel, Tecno, Infinix, Xiaomi, Redmi and other Android phones.
First, find the IMEI and compare it across the device and available packaging.
Then test the important hardware.
Make a test call. Insert a SIM card if possible. Test mobile data, Wi-Fi, Bluetooth, cameras, speakers and charging.
Also check whether the phone has been reset properly and whether the previous owner’s account has been removed.
If the seller refuses to let you test basic functions, consider that a warning sign.
IMEI Check vs Phone Test: Which Is More Important?
You should not think of this as an either-or decision.
Do both.
The IMEI check answers questions about the device’s identification and can reveal inconsistencies.
The physical inspection tells you whether the phone actually works properly.
For example, an IMEI can appear normal while the phone has:
- A damaged screen
- A weak battery
- Faulty charging
- A broken camera
- Network problems
- Water damage
- Poor-quality replacement parts
Likewise, a phone can look perfect while having an IMEI-related problem.
The safest approach is therefore to combine the checks.
Warning Signs When Buying a Phone in Nigeria
Be especially careful if you notice several of these signs at the same time:
The Price Is Extremely Low
A cheap phone is not automatically a bad phone. Some sellers genuinely need to sell quickly.
But an unusually low price should make you ask more questions.
Compare the asking price with similar devices in the same condition and storage capacity.
The Seller Refuses an IMEI Check
There is little reason for a legitimate seller to object to you checking the device identification information before buying.
If someone becomes aggressive or insists that you should pay first, consider walking away.
The IMEI Numbers Do Not Match
An unexplained mismatch between the phone and box is a significant warning sign.
Ask questions and verify the situation before proceeding.
The Seller Cannot Explain the Phone’s History
For a used device, ask where the phone came from, whether it has been repaired and whether the seller is the original owner.
A genuine seller may not know every detail, but obvious contradictions should concern you.
You Are Being Rushed
Scammers often create urgency.
Statements such as “Pay now or someone else will buy it” should not force you to skip basic checks.
A few extra minutes of inspection can save you from an expensive mistake.
Other Checks to Perform Before Paying
IMEI verification should be part of a larger buying checklist.
Check the SIM and Network
Insert your SIM and confirm that the phone can connect to the network.
Test calls, SMS and mobile data.
A phone that cannot connect properly deserves further investigation.
Check the Serial Number
Where applicable, compare the serial number with the manufacturer’s information and documentation.
Check Activation or Account Locks
Make sure the previous owner’s accounts have been removed.
This is particularly important for Apple devices and Android phones with device-protection features.
Test the Battery
For used phones, battery condition can have a major effect on the value of the device.
A phone with a heavily degraded battery may require an additional replacement cost.
Inspect the Phone Carefully
Look around the charging port, screen, camera lenses, frame and back cover.
Deep scratches, gaps, unusual glue marks or signs that the phone has been opened may indicate previous repairs.
Can an IMEI Tell You if a Phone Is Original?
Not by itself.
An IMEI is an important device identifier, but simply having a valid-looking IMEI does not prove that every component inside a phone is original.
A phone can contain replacement parts and still display an IMEI.
This is why buyers should avoid statements such as “The IMEI is showing, so the phone is 100% original.”
Use the IMEI as one piece of evidence rather than a complete authenticity certificate.
Can You Check a Phone’s IMEI Without a SIM Card?
Yes.
You generally do not need a SIM card simply to find the IMEI using the phone’s settings or *#06#.
However, testing the phone with a working SIM can be useful when buying a used device because it allows you to test calls, mobile data and network connectivity.
So, while a SIM may not be required to find the IMEI, it can be useful during the wider phone inspection.
What to Do If the IMEI Looks Suspicious
Do not ignore an unexplained IMEI problem.
If the number differs between the phone and its packaging, ask the seller why.
If a reputable verification source indicates that the device may be blocked, blacklisted or otherwise problematic, do not rush to buy it.
Ask the seller for proof of purchase or other legitimate documentation where appropriate.
If the explanation does not make sense, the safest decision may be to walk away.
The money you save by avoiding a problematic phone is often worth much more than the discount offered by the seller.
The NCC provides consumer channels for telecommunications-related complaints and information, and consumers can use official NCC channels when they need regulatory assistance.
Frequently Asked Questions About IMEI Checks in Nigeria
What is the easiest way to check a phone’s IMEI?
Dial *#06# on many mobile phones. You can also find the IMEI in the device settings.
How many digits does an IMEI have?
A standard IMEI is normally 15 digits long.
Can a dual-SIM phone have two IMEI numbers?
Yes. Many dual-SIM phones have separate IMEI numbers for their different cellular interfaces.
Should the IMEI on the box match the phone?
Ideally, yes. If it does not match, ask the seller to explain the difference before buying.
Does an IMEI check guarantee that a used phone is safe?
No. An IMEI check is useful, but it does not replace checking ownership, account locks, hardware condition, battery health, network functionality and other aspects of the device.
Can I buy a phone with a suspicious IMEI?
It is better not to take the risk unless the issue has been properly explained and independently verified. An unusually cheap phone is not a bargain if it later becomes unusable.
Final Checklist Before Buying a Phone
Before paying for a used or new phone in Nigeria, take a few minutes to complete this checklist:
- Check the IMEI using *#06#.
- Check the IMEI in the phone’s settings.
- Compare the IMEI with the original box when available.
- Check all IMEIs on dual-SIM phones.
- Investigate unexplained differences.

Conclusion
Knowing how to check a phone’s IMEI before buying in Nigeria can help you make a smarter purchasing decision. The process is simple: find the IMEI, compare it across the phone and available documentation, investigate anything that does not match, and combine the IMEI check with a full inspection of the device.
Remember that an IMEI number is only one part of the story. A phone can have a matching IMEI and still have a damaged battery, faulty hardware, account lock, poor-quality repairs or other problems.
For that reason, never buy a used phone based on appearance alone.
Take your time, test the device, ask questions and verify important information before making payment. A few minutes of careful checking can help you avoid spending your money on a phone that causes problems later.
The Nigerian Communications Commission’s regulatory framework places emphasis on the authorization and management of communications equipment, while its device-management work highlights the importance of IMEI information in tackling illegal, duplicated and stolen devices.
In short, check the IMEI, test the phone, verify the seller and do not ignore warning signs. That simple approach can make buying a phone in Nigeria much safer and more informed.
