NCC *315# Not Verified: Fix It Fast

If you dialled *315# and your phone came back “not verified”, don’t panic yet. The message is the NCC Device Checker telling you that your handset’s IMEI was not found on the Central Equipment Identity Register (CEIR) — it is not a verdict that your SIM, your line or your number is invalid. In most cases the problem is fixable: a USSD glitch, a network issue, a mismatched IMEI after a repair, or a grey-market import that skipped NCC Type Approval. This guide walks you through what the code actually checks, why the “not verified” result appears, the quick checks to run in the first 24 hours, and what to do if the result is genuinely negative — including how to use the 30-day window before enforcement bites.

What *315# Actually Checks

The NCC Device Checker runs your phone’s IMEI (the 15-digit International Mobile Equipment Identity number unique to every handset) against the Central Equipment Identity Register. The CEIR is the database behind the NCC’s Device Management System, built to identify mobile devices on Nigerian networks and block unapproved or counterfeit handsets.

What the check confirms is Type Approval — whether that model of phone has been certified by the NCC as meeting the required technical standards for use in Nigeria. It does not confirm that your SIM is registered, that your line is active, or that your number is in good standing with MTN, Airtel, Glo or 9mobile. Those are separate matters handled by your service provider.

The two options on the menu

Option 1 checks the phone in your hand — the handset whose SIM you are dialling from.
Option 2 checks another handset by IMEI. This is the option that matters when you are buying a phone that is still sealed in its box, or checking a device for a family member.

You can also use the portal at ncc.gov.ng/DeviceChecker if the USSD code is not responding. Both routes query the same register, so the result should match.

Why Your Phone Shows “Not Verified”

There are four common reasons a genuine phone can fail the check. Work through them in order before you assume the worst.

1. A grey-market import that never went through Type Approval

This is the most common cause. A phone can be 100% genuine — sealed, brand new, working perfectly — and still fail because that particular model or variant was never submitted for NCC Type Approval. Grey-market imports arrive through informal channels rather than authorised distributors, so they never enter the approval process. The device is real; the paperwork is missing.

2. A cloned or duplicated IMEI

Refurbished handsets and “London used” phones are the usual suspects here. A technician may flash a new IMEI onto a device, or two phones may end up sharing one IMEI — a practice sometimes used to revive a handset whose original IMEI was blacklisted abroad. When the register sees a duplicated IMEI, it cannot confirm the device, and the check returns “not verified”.

3. IMEI mismatch after a board swap or repair

If your phone was repaired at an unauthorised technician and the logic board was replaced, the IMEI stored on the new board may not match the one on your box or receipt. The checker reads the IMEI from the device itself, so a mismatch will show up as a failed verification even though the phone is legitimate.

4. A network or USSD glitch

USSD sessions time out, networks drop requests, and the register occasionally returns an error that reads like a negative result. Before you conclude anything, retry the check. A single failed attempt is not evidence of anything.

First 24 Hours: Quick Checks To Run

Run these in order. Most people find the answer by step three.

Dial *315# again. Wait a few minutes, confirm you have network signal, and try once more. Then try the portal at ncc.gov.ng/DeviceChecker as a second route.
Compare the IMEIs. Dial *#06# to display the IMEI in your handset’s settings, then check it against the number printed on the box, under the battery (on older models) or on the receipt. If the three do not match, you have found your problem — and it is a repair or seller issue, not an NCC one.
Test the same IMEI on another SIM. Put an MTN, Airtel, Glo or 9mobile SIM in the phone and run the check again. If the result changes, the issue is with your network or that specific USSD session, not the device.
Try Option 2 with the IMEI typed manually. Sometimes the automatic read of the handset’s IMEI fails, but a manual entry returns the correct status.

If all four checks still return “not verified”, treat the result as genuine and move to the next section.

If The Result Is Genuinely Negative

A non-approved device is a consumer protection issue, and the NCC has framed it that way. According to the NCC’s Director of Technical Standards and Network Integrity, Edoyemi Ogoh, the initiative is first and foremost about protecting consumers from counterfeit and substandard handsets. That framing matters: you have rights here.

Go back to the seller first

Return to the seller with your receipt and the failed check result. A phone sold as NCC-approved that fails verification is a misrepresentation. At Computer Village in Lagos, Onitsha Main Market or any other open market, the receipt is your strongest card — which is exactly why you should insist on one that shows the IMEI. Without paperwork, your leverage drops sharply.

Report to the NCC

If the seller will not cooperate, report the matter through the NCC’s official consumer complaint channels, or call 315 for a step-by-step guide. MTN’s own guidance on the Device Checker directs customers to the NCC website, the Consumer Portal, or NCC consumer support for exactly this situation. Keep your receipt, the IMEI and a screenshot or note of the failed check.

Ask your service provider for guidance

Your network operator can tell you what the compliance restriction on your device means in practice and what options exist before the 30-day window closes. Do this early — do not wait until the final week.

Buying A Phone? Check Before You Pay

This is where the checker earns its keep. The NCC has explicitly instructed prospective buyers to dial *315# before paying for any device, and the check works even on a sealed box.

Dial *315# and choose Option 2 while the phone is still sealed. Type the IMEI printed on the box. If it fails, walk away — there are other phones.
Insist on a receipt showing the IMEI. This is non-negotiable at Computer Village, Onitsha Main Market and anywhere else. A receipt without the IMEI proves very little later.
Know the amnesty rule. Any phone already connected to a Nigerian network before 7 October 2026 was automatically verified — no action needed. Phones bought within Nigeria, brand new or second-hand, and phones passed down from family or friends fall into this category. The risk sits with devices entering the network after that date.

If a deal looks too cheap for the model, the missing Type Approval is usually where the discount came from.

What Happens If You Do Nothing

Devices confirmed not to meet applicable requirements — counterfeit handsets in particular — will be refused access to Nigerian mobile networks. Reporting on the scheme suggests a follow-up verification process and possible disconnection after 30 days for devices that fail.

Be clear about what that means: you keep the handset. It still switches on, still runs apps, still works on WiFi. What you lose is calls, SMS and mobile data on local SIMs. And there is no automatic refund — recovery depends entirely on your seller and your proof of purchase. That is why the receipt matters more than the phone.

How To Avoid This Next Time

Buy from NCC-approved dealers and look for the Type Approval label on the device or packaging.
Avoid “too cheap to be true” imports and unboxed deals with no paperwork, however convincing the seller is.
Write your IMEI down and re-check it after any major repair, especially a board swap.
Check before you pay, every time — even for a phone from a friend. Thirty seconds on *315# is cheaper than a dead line.

The Bottom Line

A “not verified” result from *315# is a prompt to investigate, not a death sentence for your phone. Retry the check, compare your IMEIs, test on another network, and if the result holds, go back to your seller with your receipt and escalate to the NCC on 315. If you are still shopping, check the IMEI before money changes hands. The 30-day window is generous enough to fix a genuine problem — but only if you start now.

Frequently Asked Questions

What does “not verified” mean when I dial *315#?

It means the NCC Device Checker could not match your handset’s IMEI to a Type Approved device on the Central Equipment Identity Register. It is a statement about the device’s approval status, not about your SIM, your line or your number.

Will my phone be disconnected if NCC *315# says not verified?

Possibly, but not immediately. Devices that fail follow-up verification can be refused access to Nigerian networks after a 30-day window. You keep the handset; what you risk losing is calls, SMS and data on local SIMs.

How do I verify my phone with NCC using IMEI?

Dial *315# and choose Option 2, then type the 15-digit IMEI printed on the box. You can also use the portal at ncc.gov.ng/DeviceChecker. Dial *#06# to display the IMEI stored in the handset itself.

Can a phone bought in Computer Village fail NCC verification?

Yes. A genuine handset can fail if it is a grey-market import that never went through Type Approval, or if its IMEI is cloned or mismatched after a repair. That is why you should run Option 2 on the sealed box before paying and insist on a receipt showing the IMEI.

How long do I have to fix a device that is not verified?

Reporting points to a 30-day window before a non-compliant device can be refused network access. Use that time to return to your seller, report to the NCC on 315, and ask your service provider for guidance — do not leave it to the final week.
